Checkmate…

Strange, weird times are coming through. As much as the time appears to be slow because of the idleness, yet it is kind of pacing fast simultaneously. I feel like I didn't have much time since I finished my last blog post in Arabic, and feels like it was not weeks since I took the following shots that I'm going to talk about here! And guess what? Ramadhan is here already.
I'm actually grateful that Ramadan this year comes by while we are home, supposedly, instead of having to go to work and maybe sign up for a leave during the month to take care of my hysterical sleeping habits that get confused greatly during Ramadan, every year. It's such a bless for me, really.

Marbhsháinn

Well, this is just checkmate in Irish. I've mentioned in my previous post (or posts) a glimpse about my work with the chess set. I got this set specifically for photo shoots; I'm not a chess fan! Anyway been some time since I did something with this set, and so I thought it is time to work a bit. The annoying part though, working with chess can be quite noisy and loud unlike working with the feathers! If you are going to try to do anything like what I do here I hope you don't risk bothering anyone with the noise.

Воздушная Битва (the air battle)

Just as a starter, all my plans were set ahead to make these photos in black and white. Why? Well, let's just say it gives strength to the sense of drama here and also because black and white are strongly attached to the game of chess (in my case, the pieces are made of wood, and reddish and milky in color). In these shots, I've used 6 speedlites: 5 to flash, and 1 master to trigger the rest without shooting. This leaves me with one extra speedlite, the old 420EX which I didn't use here because it is, well, cumbersome to work with. I've checked the manual for this one and seems the only way to control its parameters is to be connected directly to the camera, but I might be wrong here. I got this speedlite for cheap from a friend. Anyway, adding this last one would not add much since I have 430EXII and 580EXII on both sides of the set, and 430EXII on top; Thus things were symmetrical. Why so many speedlites? Well, it was a high-speed session!

The chess set before adding the rest of the speedlites on left and right.
The white boards on right and left are for bouncing the light from the speedlites.

Now, the first shot, Воздушная Битва or the air battle, got me into a tiny trouble, which I had to solve by merging shots instead of doing everything in a single shot as I was planning. Well, several problems in fact:
  • My hand shadow from the top speedlite did cover and obstruct the shadow of the falling knight piece. Specifically the black one because I was holding the remote with my left (I'm a leftie) and dropping the pieces with my right. The problem was minor with the white knight but was a major one with the black knight.
  • As you might have inferred from the first point, I could not drop the two knights together. Working with a timer is not as precise as triggering the remote with my own hand, and holding the two knights in one hand and dropping them made them so close together which is not what I wanted. I really needed them to face each other. Thus, the only solution for this was to drop each piece alone (several times to pick the best shot) and merge them later.
Luckily, I've taken a shot before I work as a reference and that one was the base upon which the knights were merged, so in total, 3 images put together, with some edit to the shadows of the knights. Well, beside the total edit for the whole shot of course. In Воздушная Битва specifically, I like the luster on the flying black knight and in fact I've toned the luminosity of the colors when I converted to black and white specifically to keep this luster on the flying knight piece.

Фантом Кони (Phantom Horses)

Over with a high-speed shot (or composition to be precise, I guess), I moved further to the Multi or the stroboscopic flash. It's funny how this type of flash was unthinkable to me when I work with my speedlites, but now it is a favorable option when I work with such experiments. Again, I tried to throw 2 knights or horses together in one hand while triggering the camera with the other hand, but the results were not fascinating, to say the least. Thus, I needed my brother's help here and voila! It was perfect from the first shot. I had though to use also another shot for the background to merge it because my brother's hands shadows from the top speedlite. I'm not sure how many strikes of flash were there but I'm guessing 5 from the number of "ghosts" in Фантом Кони, and surely the frequency was low, probably 50Hz. In fact, 5 strikes of flash when working with stroboscopic light is now my standard and my starting point. It seems to yield some reasonable results in most cases. One thing I regret though in this shot is that I didn't ask my brother to hold the horses opposing each other face to face, so as you can see they are falling here and both looking left.

Кто Стоит Последним (who stands the last)

Next in order comes a simple shot, yet hard in the same time. At this point, and in order to shoot Кто Стоит Последним, I had to change the lens. In the previous shots I've used my Sigma 12-24mm and that's out of necessity a bit because the perspective needed to be adjusted a bit because of the tripod's stance. However, with Кто Стоит Последним, I had to change the lens and use Voigtländer 20mm lens so that I can use my polarizer. The Sigma lens is 82mm in diameter and I don't have a filter that fits, and converting rings (step-down) would be problematic. Thus, it was safer to just change the lens to Voigtländer 20mm which has a diameter of 52mm. The polarizer was needed here to emphasize the reflections of the pawns or pieces on the board.
The general idea for Кто Стоит Последним here does not involve any speedlites, but simply some dark atmosphere, dark enough to give me a long exposure. Meanwhile, as the exposure is on, I would be changing the placements of the pawns and keeping the kings in the middle without touching them. I was pretending to play a game of chess (don't know much about chess anyway!), so I kept knocking some pieces down and changing the placement of some others. All of this mess of course produced some ghosts, as needed. Good thing though that I didn't knock over the kings or move the board by mistake; With my Retinitis Pigmentosa in dark places thing could go... astray. Total exposure time was around 4m30s; And I guess this is exactly the time needed to defeat me in a game of chess, if not less!

Báisteach na Ridirí
(the knights' rain)

Then I had this idea, which was kind of "crazy" a bit, but I'm sure not as much crazy as other people I've known (nor my life). The trigger for this idea was that: since I've been editing or composing and merging my previous photos (except for the one using long exposure above), then why take a step further (just a bit!) and make a rain out of knights!?
I realized from the beginning that I'm going to need a lot of work done here, and as if it wasn't hard already, I had to struggle with batteries and power resources for my speedlites as I was preparing them to shoot high-speed. A LOT of high-speed shots.

Идет Дождь Коней
(It's raining knights)
My thought for working with this "project" was to divide the work on separate sessions, with each session being dedicated to shoot a specific portion of the image:
  • Shooting the 2 kings at the center of the board (and fixing the focus at that point).
  • Shooting the plain board.
  • Shooting the dropped white knight piece on various locations from the back to the front and sweeping left to right each time.
  • Doing as with the white knight but this time with the black one.
  • Doing as with the white and black knights but this time dropping them both together.
The last point here was actually eliminated later and I didn't touch it because of the crowded image that later became to be when I worked with the white and black sets separately. The plain board shot was kept as usual as a backup; I didn't really use it. All shots were done with the same light, same shutter speed, as much as possible. Because I was dropping the pieces on the board, there had been tiny movements that would be visible only on comparison but they didn't have a great impact on the merging process; Excellent!
I won't go into details here about the way I organized the files and merging them, but I'd just say I've followed a systematic way (and the file size was enormous). Not all images (more than 52 in total) were used; Some of them had to be canceled for various reasons. You might have noticed in the image above that there is a knight blocking the black king and I left it there intentionally to give depth and dimension to the image.

The white and the black sets separately when combined. Of course there is a number of them that were removed in the final image shown above. Merging them alone makes some nice shot it seems so I will try this later!

Unlike the previous high-speed shots, I've slowed down the shutter speed here to 1000-1s, down from 8000-1s (max for Canon EOS 7D). I was hoping to capture some motion blur for the falling pieces, which it did, but not to my desire. The view on the camera's LCD was not good enough to judge, but anyway, I continued working as it is. After finishing the merging of the white and black pieces layers, I've tried to do the same with the doublets (those shots I've made for dropping the white and the black knights together, using one hand) but the image looked crowded already and no need for more. I'm keeping this set though for some editing experiments!

The Falling
One of the "doublet" images that I decided to not include in the final image.
Using the polarizer really paid off.
I had some ideas also to do an experimental light painting on the set before I move on another idea in my work with the camera but I couldn't find a suitable method or idea to apply here, and probably I don't have proper tools to do such delicate painting for small pieces like that. Most of the time, as I've encountered so far, light painting is done on a larger scale a bit and not a delicate one like a pawn and a chessboard.

Finale

Crazy times, and I'm trying to use every minute I could to the max, with my camera. Well, maybe other things as well (gaming for example?) but I'm on the go and trying to try more and more with my camera, in hope of creating something unique still.
Meanwhile, thoughts of leaving my work and do something on my own still roll around my head, as I'm not sure how stable my current job would be still. yet, I'm grateful for the situation now, but nevertheless I cannot guarantee anything in such times. Not sure where I'm heading but I'm trying to take it one step at a time, and enjoy as much as I can. If only I can control the damn mood swings.
Being in lock-down and home quarantine might not be as a catastrophic for an introvert like me, as it would be for an extrovert. Yet, I do have my feelings towards it. In such times, my eagerness for traveling has increased ten-folds than before, even though I didn't know before this crisis whether I can travel or not and probably I wasn't ready for it, but now I really need it to just change the scenery and be away from people. As for me, I don't go out of home much already as it is in normal days so a quarantine or home-stay won't make much difference, but it s the general atmosphere and the people around that would just push your buttons up and down and screw up that peace that I've been trying to work on for quite some time. I need to travel probably to change the people, and not the scenery. It is in such times I just so wish that I have a home of my own, but in a place like this, how would this be possible at all…

3+3=4…

I wasn't sure that I was going to type something in this blog for this week, but I'll try to pass this as fast as I can. Ramadhan is here already and my time is consumed greatly. By consumed, I don't necessarily mean "work" or anything else; but it could simply mean being tired and unable to do much.
After breaking the fast, I spend my time doing some usual chores and if I can get some time I would be working with my camera somewhat (if any idea was available). I'm observing this for the upcoming weekend, though I'm not optimistic about it with such family gatherings in weekends. I decided to fight sleeplessness and the upheaval in my sleeping pattern by reducing the amount of food I eat after breaking the fast, and I must take it at specific times. No fatty dishes, just dates and some bananas with milk (sour milk).

Meanwhile I was able to do some experimentation with some idea that I've been thinking about for a long time now and I'm finally on the move to do it. The idea is creating a so-called 4D image.
The problem here lies in the fact that I don't really have any imagination or any expectation for the outcome. I'm merely working by the concept and the theory of 4D space. That is, merging 3D shapes with each others would raise the dimension space further, to 4D.

4D Hexagon
an old experiment done by merging 2D hexagons with each other to form 3D Hexagon, then merging two 3D hexagons to form 4D hexagon, supposedly.
Probably this concept is best illustrated by the tesseract, or 4D-Cube. Anyhow, from this point and concept, comes the idea: what would happen if I could merge two 3D images? What I'm going to see, and what I'm expecting? Up till this moment, I don't really have any answer for this, and the main factor that keeps my mind busy is how to shoot, and how to merge?
As a principle, I've realized that I would need at least 4 shots. In the beginning I used my 100mm macro lens with a chess set, and using a shallow depth of field, but then I've realized that a shallow depth of field is not even a good thing to create a good anaglyph or 3D image. Thus, I've changed to 50mm and using f/8 (or around that). I've taken several lateral shots (sliding the camera to the side 1cm between each shot), and once again four other shots rolling the camera back to front. However, I ended up using the lateral shots alone. My idea was adding some depth somehow using back-to-front images, but it was puzzle that never worked out.

End Result

There were many trials and merging several layers by combining these 4 lateral shots. I won't go into details, but the major problem was how to merge or blend two 3D images? Not to say, upon which point (or focusing point) should I base the alignment of the two 3D images? I ended up using the front knight as you can see above, while blending the two layers by trial and error (ending with using the Darker blend).
For comparison, I've put the End Result above, which has a comparison between the regular 3D and the supposedly 4D, or the merge of two 3D. The two must be, supposedly, viewed using anaglyph glasses (red-cyan). I need some feed back on this, so if you can do this in the comments section I would appreciate it. I cannot rely on my own judgement alone on how this 4D looks or feels. As a beginning, it seems that the chess pieces were broadened and became thicker than the original, and as for the background it looks shaky. At some point in my experimentation before reaching this result, I've indeed made a version where the knight piece in the foreground was stable, while the other pieces looked shaky and blurred.

Finale

This is all I could put on for this week, and I'm not sure I will be posting for the rest of Ramadhan, but I would if I have any new ventures and experiments. Probably I should neglect photography a bit during this month and work more with my Geltani? Maybe.
Anyway, if you are reading this, and have the possibility to view the End Result above with red-cyan glasses, please leave your impressions in the comments. It would be a great help to understand how other people perceive this "trick"!
Time to manage my sleep now, again…

Checkmate!

Still going on with the chess board experiment after borrowing the board for a second time from my friend. This comes after a sorting session which we had a week ago. The leader liked the concept but suggested that the knight should be larger and, in other words, the board be turned into a landscape-like setting by the usage of wide angle lenses. Unfortunately, things didn't go as I hoped.
I didn't have much options in my hands, but to use my Canon EF 15mm fisheye lens, for a number of reasons:
  1. On my cropped-frame camera, this provides a suitable wide angle without going extreme, like the Rokinon 8mm fisheye lens.
  2. Using flashes might produce some artifacts on Rokinon's 8mm fisheye lens. 
  3. Minimum focusing distance is 20cm (7.87in) for the 15mm lens, but it's 30cm or more for Rokinon's 8mm fisheye lens.
  4. Seeking clarity, the old kit lens 18-55mm is automatically dropped out of consideration, adding to that it has no scale for focusing.

Anyway, after all these points, the common problem was and will ever be, getting closer and creating the optical illusion I was seeking. Extension tubes, with a minimum of 12mm, was quite problematic and I had to keep the knight almost touching the front of the lens (literally). After all, I've cancelled the idea of extension tubes and decided to work with the lens solely. However, another problem arose here: too much unwanted details in the scene because of the wide field of view. Solution: crop. Then another problem arose: the final image size won't make it even to stock images websites. Solution? Well, Super-resolution (SR).

Last One Standing II
Canon EF 15mm fisheye, f/6.3, 1000-1sec, ISO100.


The technique of "SR" is something I've read about long time ago and I didn't apply it much to my work, simply to the fact that I do work with panoramas most of the time; images are already super in resolution! Anyway, it was a good chance here to apply the concept again since I'm going to crop the final image. I won't go into details here, but the process is simply done using some software and a number of shots for the same scene. Shots are merged then and a higher resolution is produced. The final output can be 3 times the original resolution of the image out of the camera. Anyway, despite the final output here, the composition itself wasn't to my liking after all.
Still trying to figure out a specific trick, I even tried to do a "macro panorama," if I can call it so. In other words, I tried to do a panorama for the set using a macro lens (Canon EF 100mm f/2.8 macro). However, this method proved to be a failure because of the parallax error, beside the fact it didn't really achieve the perspective needed. After all, I had to just abandon the idea for the time being as I realized the fact that it cannot be done with the collection of lenses I have right now. Instead, I made another idea, which I've entitled: Nobles.

Nobles
Canon EF 15mm fisheye, f/22, 250-1sec, ISO100.


The idea of this setting is, supposedly, a revelation of how a community works: nobles standing, and the rest of the pawns falling. Well, I'm not quite sure how would a chess game work, but I think it depends highly on the same concept of sacrificing the low rank to save the high one. I tried to keep the setting random and not organized, but unfortunately, it seems I was mistaken with this decision; as the board looks clogged and probably featureless. To snap this shot, I've used the 15mm fisheye lens again and raised it (with a downward tilt) behind the black pawns. The aperture had to be maximum here to ensure the sharpness of the whole set (and this is how the concept of landscapes work); yet despite all of that, the far pawns came out out of focus a bit. I think the focusing point was a mistake too. After doing the SR technique, again, I've worked on some aspects as well, like applying"fake HDR" technique to make the scene more vibrant. Ah well, something to be over with, as I have more projects to look after. I will come to those later.

Toys

After the recent workshop I had about high-speed photography, I've decided to go further with my flashguns and I got myself a power source: Nissin PS-8. Probably I did mention this fact in a previous post? Or was it my Arabic blog? Anyway…

Source: B&H
As can be seen, this power supply can feed 2 flashguns at a time which is beneficial since I had 2 flashguns: 580EX II and 430EX II. Unfortunately, it comes with only one power cable and I had to find a second one. After roaming all around the known shops for such accessories, I couldn't find it. Thus, I've decided to place an order this time and order some "toys!" Along with this cable I need, I've ordered extra cables for a friend who has a different model of Nissin power pack. I got to say, those are not cheap!
Since I'm placing an order, I had to add more items to make it worthy the shipping price I'm paying here. It's like hell now too with oil prices going down (ironic eh?).

Source: B&H
 My most previous toy in this package is something I really need in a long time now. A wide angle lens (but not a fisheye type), and preferable with some good quality! And I decided to go for it right now with Voigtlander Color-Skopar 20mm f/3.5 SL II N Aspherical Lens. The brand, Voigtländer, has a long history in optics and probably it comes second behind the well known Zeiss. I needed this lens specially with the absence of a proper focal length among my lenses in that range, while the old kit lens is no good anymore for a serious work! Would it be suitable to do a panorama? Who knows! The lens is manual in design but with autofocus capabilities which I didn't quite understand in the specs - but probably it is meant that when pressing the shutter button half way, the camera, and through the lens, would give a beep if the image is focused properly. I would love to try this lens with extension tubes as well, specially that according to the specs, the design of this lens is made compact. My hand is already itchy to use it!

Source: B&H
Along with the Voigländer lens, I've decided to cover myself and ordered a step-up ring with it, i.e. a ring that enables a larger filters to fit a lens with smaller thread (smaller front that is). Voigtländer 20mm lens here has a thread of 52mm and most of my filters are in 58mm format. Not ready to buy all the filters all over again and just for a single lens! Well, I'm planning to increase the arsenal of prime lenses in the future but not yet in urgent need for that.

Source: B&H
My last toy was actually from a local store and not ordered from outside. Not only it is discontinued, but I'm also in a hurry to get it to do some of my experiments with my camera. It is Canon's Speedlite 580EX II. For some time I was thinking seriously of getting something cheap like a Yongnuo flash, which many professionals use as well (the important thing is how to use the light). However, from a quick overlook, I've realized that most of those do work by radio wave in wireless format and not optically. Canon's latest addition, the 600 EX-RT, is a powerful tool and addition, yet unfortunately it could deem the usage of my two other flash units dormant and useless. In a lucky gesture, a local Canon store found the last piece in stores of this flash unit (but unfortunately, no discounts since they realized how much I need it!). Nevertheless, I'm happy with the new addition (and the new power at hand). However, this is not the end after all, and more light sources can be good as well!
There had been some other orders from Amazon, like a set of 100 pair of anaglyph glasses and a new book, but I guess I'll keep it for later.

Projects

As for my on-going projects (that is those related with my camera and not my poor conlang Geltani), I do have a list of things to do and I'm trying my best to concentrate on some of the themes listed in the upcoming Trierenberg Super Circuit; mainly the themes of Selfie and Red. I have some problems concerning the two themes. As for the selfie theme, I'm planning to do a high-key (and I have to learn it the hard way) and it must be done in front of a mirror. The problem arises when it comes to a proper location and a proper mirror. With three flashguns now, probably lighting for a high-key won't be a problem (if the room is small enough). The other theme, Red, is mysterious to me as I'm not sure what to do here. Probably the whole thing would end up with a gel filter on one of the flashes and THAT is something I'm trying to avoid, simply because it is just a cliché and not innovative much. Anyway, probably I have to sort myself to this idea at the end if I couldn't come up with something. I do have some old images that might fit such a theme, but I'm trying my best to create something new.

Finale

I'll be busy this coming week as I've started a workshop for Abstract photography, and directly after that another workshop will kick in: Philosophy of Colors. Meanwhile, I'm trying to do my own projects with my camera and even though I'm not working on my Geltani conlang but the thoughts are visiting now and then without being penned down. Add to that some obligations (mainly to my group) and you will have at the end a mesh grid of a mind. With all this mess and fuss, I'm still not finding this is enough to stop looking back or remember my pains; they just keep getting in whether I like it or not, whether I'm busy or not. They do have some way deep inside within me.
My health is getting better now after the latest visit to the doctors and doing allergy tests and all. Thank God! Finally, something good to contemplate over. I'm going to post this, and get ready for my busy weekend to come… let's just hope by next week I'll be having some good results…
