A Micro Job…

Well they had been some easy-going weeks, relatively, but with me back to work there is also the lack of time and energy (typical) to do some of the chores or projects I set to myself. But after winning a gold medal, I think I need to get some rest, yeah?
Well, my rest is not a real rest here though, with many other chores I need to do. First things first, I had to print my winning panorama as a gift for an old friend, whose uncle is actually the deceased Kuwaiti Icon, AbdulHusain AbdulRidha; for whom the whole thing was done after his death as a tribute.


The image here (without the external margins outside the black border) was about 175x79cm, and that's way greater than A0; The largest size in the A-series of ISO 216 standard (the typical standard of papers here). Thus, my typical go-to printing shop was not an option since they don't print larger than A0. I had to go to the main branch of that printing shop (and I was surprised that it's now owned by another company in fact). Anyway, it took them some time to print it (which triggered a headache for the lack of sleep). I tried my best to keep this file at its best of clarity and resolution, so no wonder the file size was a monster! An almost 1GB 16-bit TIFF at 300 DPI! Such a gigantic file caused their system to crash (according to one of the workers there) and they had to re-open it on some other system and try again. Makes me wonder, really, how come they can deal with this file as I do while their PCs or Macs or whatever were connected to those big large format printers (dedicated to posters and other types of prints)?
I've chosen canvas as my medium here. Their canvas material had a finer and smoother texture than the one I usually print on and in fact, in some sense to the touch, it does feel like if the canvas had been already glossed. I didn't bother to apply any varnish on the print with this relatively-new material to me; I was afraid that it would ruin the looks and it's really not a good time for this! Thus, I went along and just wrote my dedications on the margins (after shooting the video above).

The Other-Wise

On the other hand, I've not done even a little with my camera, but still doing experiments on and off with my microscope. My shaky, microscope. There is a great hope here. First of all, I'm not afraid to use the 40X objective anymore (unless the beauty of the details calls for a lesser magnification). Then, it seems that I've somehow managed to have even a better position when shooting the eyepiece with even greater magnification (all by coincidence), but further investigation is needed here since I'm still unsure of how to calculate the magnification in that position. I'm aiming on achieving something beyond 1000X magnification; And somewhat I think I've done it (if my calculations are correct).

Aspergillus
~ 1280X

I was blessed with a friend who works in the biological field and offered me to prepare a sample of a fungus. He also toured me through some of the microscopes where he works and I was really impressed (though my eyes was problematic to view some samples through the stereoscopic eyepieces). Now for the image above, the magnification should be around 1280X (40X objective, 10X eyepiece, 3.2X reversed 20mm lens on camera). The original sample was blue as, according to my friend, the sample has to be stained to be recognizable in a good way. However, after the merge of 4 to 6 shots, I've corrected the colors (using the 3-point correction on Curve in Photoshop). The image is also, in fact, a third trial after 2 failed attempts. In one of these attempts I was trying to shoot using my Sigma 12-24mm in reverse! With that lens at 12mm in reverse, I could have achieved around 3300X theoretically! However, the images were quite unclear and I definitely need a more stable environment with a brighter light source.
The second attempt, also a fail, was using the 20mm lens in reverse and, by coincidence, discovering that I do not need to get so close to the eye piece to take pictures of it (only if I want the image to dominate and remove the black border of the eyepiece). Somehow, the concept is like a projector and a screen: the further away you put the projector from the screen, the larger would the image be; Only thing left is to re-focus the image. The only thing, though, I wouldn't know exactly what the magnification power would be with a distance between the eyepiece and the camera! But sure thing it would be something greater than what would be calculated usually. What is left now is, to do some infrared work as well to see if there is anything special about it.
With the help of my friend, we've taken some shots using my smartphone at high resolution, and from both eyepieces of the microscopes in order to merge them later (hopefully) into an anaglyph if possible. These shots were taken at 400X and I might post them in the future. When I compared some shots from the mobile and the image I've done above, it is apparent that the shallow depth of field exists even in such good microscopes (the details of the granules were not clear) and it's not very different from my own very old microscope - and I thought such a problem would have been solved already - So, I guess, there is a call for photo stacking EVEN when using an advanced microscope!

Trying to measure the width of the hypha (if this is what they call it), at about 2475X.


Shy Green

There is one poem which I've written few weeks back but I didn't post about on here. Since then, though, my mind got blocked with many events, chores, and responsibilities which I need to attend to. Words come and go, but I don't even have the time to push further. Anyway, I called this poem Shy Green after getting inspired by a photograph I've shot in Cahir, Co. Tipperary, back in 2010 - My second visit to Ireland.

Stormy seas, by the winding fear,
calmly standing in a shy green,
My heart in hope to set a clear,
gazing about a peaceful scene.
Miracles happen so it's seen,
but none to a beauty I know,
tranquil, alone, battling off the snow.

My sighs, that which all I could give,
a tear, a caress, or a thought,
But would my gentle one just forgive,
a wretch like me, happy in distraught?
By this grand asylum, I'm caught,
and the blooming shy abounds me,
when all that I dreamt of, not to be.

Charming in loneliness set,
what a rose had an ill such luck?
Take my palm and never get wet,
and thy green, may never get a pluck.
Thus, when the nightmares are struck,
my heart shall keep you by finesse
then on that headstone, chant me a bless.

Shy Green
In this poem, I've used a rhyming theme which I've never worked with before or heard of (probably challenging myself?) with the help of Verse Perfect. The form was called Rime Royal and goes: a,b,a,b,b,c,c. An odd number of lines is required, so it is kind of challenging to connect ideas that way, somehow. 
There had been many instances of inspiration in the past weeks, either from events or photographs which I've shot and edited myself, yet there was a lack of something that kept away from typing few words down. Not sure what it is, but maybe... motivation? praise? desire? I'm not sure really. Let's hope this blockade shutters off my mind soon. I need to write…

Finale


The past 2 weeks were quick and slow at the same time somehow. It's a weird feeling. Ramadhan is drawing near and I do feel the sleepless and tiresome nights already before its coming. I've signed for a leave already, but still I will attend to work for the first 10 days of Ramadhan. Traffic jams now are unbearable because of the stupid time management we have in this country where and when people all must go out of work at the same, making Ramadhan itself as worse in jams than regular days despite the shorter working hours during this month. I'm typing this with a sigh. Hopefully though, I will be able to work more with my camera and do something useful more than what I usually do in these regular days. Let's hope.
The whole story about the microscope and the works of the microscope made me think of seriously getting a more "advanced" one (since my friend been nagging on my head actually) but the idea was actually abandoned quickly; or was it? One thing for sure, I can't get this right now as I'm mingling with budget issues and other priorities. My friend's view was quite "profit-wise" as he looks chanced to get more money in any way possible. That's not me really. I still consider it a hobby and something that ignites that long lost childish curiosity in me. I did have my dreams about having a telescope and connect it to the camera as well, and this is such an old ambition which I'm not considering right now as well. 
As for the time being, as you can see, I'm still editing my old photos from time to time with some focus on weird crops and ratios to bring the attention of the viewer. Even lately, this activity has come to a perigee because of the other chores I need to do (including typing this blog which takes some time to do). On the other hand, I'm waiting for a new shipment of books and something that I think it is too good to be true but I can't judge till I see it with my own eyes (and test) - I'll talk about these books and "things" later in the future. Now... where did I put that pillow and blanket…

Dear Camera, See You Later...

ayħav húþ ğašar mí e-harrá yaw e-dum yi hú báy
lávin anná húþ baZú daynúr majŧún?
šá ąél kil mší yixwan gavvá liQiliváy?
mat hú zmén e-ranáħah, liZú ąayun?

Some "Ayvaric" thoughts has been around, trying to change or edit the literature that I've been inventing for some time now. This time, it occurred to me that usually in English, the word "between" is used usually in combination of two objects, while "among" is for objects more than two. Thinking about it, there is the same thing almost in Arabic and Hebrew (I guess), but it's not a number-related. There is "bayn" [بين] and "ma bayna" [ما بين], but I'm not sure of their exact classical use. To me, I seem to say them fluently according to the speech but without knowing the grammatical reasons for this! In Ayvarith, there is a similar situation even though I've made up some explanations for this without really noticing them myself: (bayun) and (mabyun); clearly close to the Arabic version, but as far as I remember the Hebrew and Aramaic versions are not far from this either. I'm thinking of upgrading the meaning to make (bayun) used for two objects while (mabyun) for further numbers above two. Just a thought.
I've renewed my account on Writing.com for another year. Doing that sort of gave me the pinch to keep up with my other projects. A very bad habit of mine: starting things and never finish them up. I'm looking forward for more tiresome days specially during the summer and the heat here, with the expected renewal of my duties into field trips. Field trips, games, photos, daydreaming, a conlang and poetry (specially poetry. I didn't write in some long time now with all the gush in emotions in my mind). My life truly is a mess that went out of control. Trying hard to keep up and organize my time and even exercise to enhance my physical vitality to cope with my own requirements and my own projects, but even that require time, and to screw things completely, sometimes I'm ready to screw up the world and sleep. Just sleep, like I always wanted (but that never really happened).
I think I do need a vacation from my camera. I don't know why I feel the need to take pictures so often. It's becoming like an addiction, and every addiction is simply bad, be it drugs, drinks or even a hobby like photography. But what you know, once I'm dropping down the camera I'm going to head to that Ayvarith project and web page that I didn't work on for some months now.
I'm back now with my own research about myself, my brain, my skills, and how everything works together. Most of such research is done at work actually not back home, because simply back home I don't have time now to sleep, and if I did, I'm going to screw up the day and just do nothing at all (probably only play those games I want to). With this said, I'm back to some of those free tests online (yep, another addiction), and along with that a belief of some thread of ADHD in my (neurological) blood. While reading The Playful Brain, I'm paying more attention to my simple actions and notifications and trying to analyze them under the light of what I've understood lately. I've noticed what is said to be an "easy puzzle" can take me a longer time to solve more than what is supposed to be a "hard puzzle" of the same type or rank. Also, I've been fluctuating my attention from one object to another (looking at a book to pick it up, and an agenda lies in the way between me and the book, thus I remembered something suddenly for that agenda and picked it up totally forgetting what I wanted to do with the book). Looking at some videos on Youtube about ADHD cases makes me feel superior though. It's not like that with me and yes, I don't think I do have ADHD at all now, but why do I lose my focus that easily? Why I keep flipping channels in my mind? Is it the damned Maladaptive Daydreaming again? I know that I've not been the hard fighter lately against this habit, mainly because I'm exhausted and in fatigue.

Decision is made now. A break from the camera for some time.

I should add to that a break from chocolate and coffee as well. Speaking of my mental status as well, in fact, I don't care much anymore about what people think of it now, but I like to explore my mind little bit further. I'm doing some EIQ (Emotional IQ) tests but I don't count on such results as the questions tend to be highly relative to the culture I guess, but anyway, my score was low. Not surprised though. I'm a loner after all.
On the other hand, I'm back to my senseless sketches as the attacks of boredom do visit me at work from time to time and makes me unable to read the book at hand...

The Devil's Automobile
The idea was to create a head with some brain popping out of it, but with such epileptic art form, expect the unexpected.

Sensory Man
This sketch was done horizontally (90 degrees to the left or CCW), and my mind didn't make sense of it as usual except later when I changed the angle of view and rotated it 90 clock-wise to realize it looks like a man's face.


Now back to my camera before I leave it alone for some time. I did my experiment now for catching a flowing water with the help of ND filters, and hence I couldn't use my Tamron, but instead I've used my old Canon 55-200mm, because I do have an adapter ring for the diameter of this lens (Ø52mm). The result was not exactly what I wanted, specially when it comes to the angle of view, but it was some trial that I hope I've learned something from...

Aqua Viridis (Green Water)

The whole problem is about doing the right exposure under the green flood light. One of the techniques that I've came up with is to use the (M)anual mode completely to achieve this. The (M)anual mode gives you the ability to change the shutter speed and the aperture (f-number) as desired and with a half-press to the shutter button the camera would give out an estimation of the light level in EVs. Everything was fine, except of 2 points that I was puzzled with:
  1. Where to focus? to the furthest edge or to the nearer one? Here, I tried to focus in between (I focused without the water flow in the beginning thus it was an approximation).
  2. What aperture size should I use? I used maximum f-number (narrowest aperture size) but probably I should have applied the principle of Hyperfocal distance? Though I think this concept is mainly used in landscape photography and not in close-up photography.
The main important thing is that I've fixed the shutter speed. Few seconds were enough to make the water flow in a blurry way like a dream effect (in fact it looks like milk to me!). After setting the shutter speed to 3 seconds, and the aperture to f/29, I did simple half-press, checked the EV and then put on some filters corresponding to the mount of EV I want to reduce. The EV reading without putting the filters on was close to +3, thus I've fixed three ND filters: ND2, ND4, ND8. They correspond to a reduction of -1, -2, and -3 EVs respectively, and thus totaling -6 EV putting the scale down from +3 to -3 (3+(-6)=-3, simple calculus). However, even though the picture was fine to some extent, I had to edit the RAW file as well and adjust some sliders and finally, with the help of adjustment layers in Photoshop, I've removed the green color from the background and kept the water and the mug in green only. I'm not satisfied with the sharpness of the water flow itself.

And still dwelling in the bathroom trying to catch up a panorama for this narrow place. I think it's around 2x2 meters (~ 6.6x6.6 ft). It is indeed a challenge to do a panorama in such space. The only panorama, probably, that I did in such a narrow place (and without the VR-head back then) was for the inside of the little tower back in Aughnanure castle in 2009...

The inside of the little tower in Aughnanure castle field, Co. Galway, Ireland.
But, this panorama, taken without the VR-head and definitely a narrower place than my bathroom, but after all I minimized it to 360 panorama (horizontal line only). The hardships of the bathroom were different, specially that I wanted to take the panorama from a level higher than my head, and this time I used my new tripod and not my monopod.
  1. With a tripod, the base was stable, but the tripod's head itself was shaky a bit making a small tilt for the VR-head on top of it.
  2. The narrow space of the bathroom made the lower angles, where the tripod's legs show usually, a serious issue.
  3. Tried shooting with flood lights and not my usual bathroom lights, but the ceiling's plugging point was narrow and the flood light could not be fixed there. In order to solve this problem I had to think of some way to lengthen or extend the plugging point further. Luckily, I got some converting heads (for light bulbs) in the family shop near by and connected two of them to extend the plugging point. I had to work on smoothing the edges a bit because they didn't fit in the first place so I had to widen one converter and narrow the other. I have to say I was working for more than one hour taking the panorama and afraid of this bulb to be falling down on my head at any moment!
  4. The usual problems with the stitch in PTGui, but this time accompanied with a glitch from Photomatix when merging all in HDR format. Seems that the new Photomatix has a glitch in batch processing bracketed images. Usually I see such errors and broken lines when different images are merged by mistake, but this time I double checked my images' sequences and there was no mistake. Simply, this one particular slide which showed a strong error had to be done again alone separately. Only then, the HDR slide for that angle appeared perfect.

The flood light with extension made of converting heads (or plugs). The arrow points to where drilling was used (with a special head to soften the area and not drill through it)

The right side of this HDR (tone-mapped here) slide became partially white with broken lines even though the bracketed sequence is correct! It wasn't the only slide, but it was the worst...

The whole point of using flood lights here and not the regular light bulbs that were already there is that I wanted to avoid the WB (White Balance) problems that I had before in my first experiment in this bathroom. If you read my post last week you'll find an explanation of the problem and how it was hard, somehow, to choose a particular WB with such lights. Here, after fixing the flood lights, I've simply shot the panorama with Daylight WB.
As for the glitch in Photomatix, I thought it might be because I was setting the options for reducing the "ghosting" artifacts to "high" while the camera didn't shake so much and there were no moving objects to eliminate, thus I processed the package again in a batch process but turning of the "ghosting" correction off. Yet, the weird artifacts kept on coming.
It is always hard to set control points for the make of a HDR panorama, probably because of the exposure data embedded in such files that makes PTGui unable to set the control points properly. However, I've tried the old trick which seems to be working fine for now (but that didn't spare me the troubles): tone-map the HDR slides under certain settings, then stitch them and save the file as a model. Then, open the HDR panorama file and apply that model. That way, all the control points that were applied perfectly for the tone-mapped images will be applied to the HDR panorama in the same systematic way (providing the control points are perfectly situated in the tone-mapped model). I've stitched the HDR panorama then without even optimizing. All the errors that occurred while trying to align the HDR images disappeared simply depending on the tone-mapped counterpart. Why not simply tone-map and then stitch? Here you go:
  • HDR panorama will have exposure information rather than a tone-mapped version (even in 16-bit TIFF). This option gives you more control over the light effects.
  • There are occasions when you think it is better to manually edited the HDR file for some reason (changing hue before tone-mapping, changing exposure of certain areas only before tone-mapping, ...etc).
  • If you are thinking of making a QTVR (QuickTime Virtual Reality) file, it is important to match the exposure of the left and right sides of your panorama, otherwise in the QTVR file you will notice a strange straight line while rotating your QTVR. This option, to match the two sides in exposure, is available when you tone-map in Photomatix (and other programs), while stitching already tone-mapped images won't give you such an option and you might have to find other ways to solve the problem.
  • PTGui got an option to fix the exposures for the whole HDR panorama before stitching. Useful sometimes to make an average of all the slides' exposures.
After stitching the HDR panorama, there was a heavy load of work with Photoshop to clone out lot of the undesired objects to make the panorama normal as much as possible. Parts of the VR-head did appear so much in this panorama specifically, and it is hard to simply remove by cropping; I have to clone out instead. I think it is time to re-consider the way I work with vertical angles, as it seems a 45 degrees up and down is causing me problems! Beside these parts, some weird artifacts in red appeared as well, and still I can't explain what are these as there is simply no reason for them to occur!

Lavatrinum
My bathroom, and still you can see some red artifacts in a larger view. I had to cut out the roof because the green light was subjected to "poster" effect, or banding artifacts.

And one of  my biggest mistakes, again, is using a large f-number (narrow aperture) causing a lot of sparkles caused by the lights. If I remember correctly, it was f/20.
After this panorama, I think I will get back to the sweet old Photomatix instead of the new one because there are many issues now that I've noticed that are caused for no specific reasons. Such glitches didn't appear in the old Photomatix (version 3). The only problem with the old Photomatix was the weird squares that appear on the viewing window (I think related to the insufficient memory as my PC runs for long times). So just to be systematic:
  • The new Photomatic (version 4), has a problem in tone-mapping window. As you work according to what you see while you tone-map, once you hit the "Process" button, the final image would come different to what you have seen in the tone-mapping window.
  • The new Photomatix has a problem with batch processing RAW files. As it turned out, some HDR slides were merged with strange white bands or broken lines (like what happens when two different or so much shaky images are merged), while when these specific slides done as a single process, this problem doesn't occur. Talk about time-consuming!
  • Related to the problem mentioned in the beginning, some weird artifacts, in form of colors or shapes, appear after tone-mapping (e.g. in my example above, red areas appeared and had to be cloned out, and banding of some colors making gradual change appear as blocks of pixels).
I don't think, however, I'm going to do it all over again with the old Photomatix, but I learned my lesson I'd say. I have to check further with my VR-head and the best way to deal with low angles to avoid including the body of the VR-head itself into my panorama. It's not completely evadable, but at least the effect can be reduced somehow.

Finally, my order(s) had been processed and I'm waiting for their arrivals. I'm doing it slowly so that I'd have more time reading The Playful Brain. Three photography books, one teleconverter, and a sound trigger. Did I say I need a break from my camera? hmmm......
