Official...

Surprises (or should I say Semi-Surprises) still have a plenty for me to show, and it is yet still the first month of the year.
It is official now. I've been diagnosed with Retinitis Pigmentosa by a specialist, after checking all the results of the tests I've done in the past 2 months: Field of View (FV), OCT, and ERG. I'm not sure how did he really read my results without a close-up inspection to my eyes, but he depended, as it seems, on the ERG test result which I've done last Thursday. I'm not sure what's the next step, but anyway the doctor said that he cannot make up for how severe it is. When he asked if I do suffer of anything, I simply replied what with what I feel and what I've seen: Nothing.
Anyway, more about that probably later. I'm somehow happy for this past week for a number of reasons which I'll be talking about below.

A World of Pajero

I've finally had a chance to do a panorama for my new car; Pajero 2014. The panorama wasn't any easier than the one done with my old car, Seat, despite the relatively wider space inside. This is mainly relative to the size of the tripod and the bulky nature of the panorama tools I need to use. This in fact sparked me to think seriously about finding some alternatives somehow.

Pajero 2014

Even though I've stated before that I'm not going to use the parking lot in my work place because I'm disgusted of that place, but anyway I've come up with a solution just to avoid suspicions. That day, however, I had to wash the car and make sure it's clean of dust and I had to remove all the plastic sheets covering the seats (as in any new car). After doing my fingerprint scanning to leave work, I've went to the back of the parking lot as if I was leaving but instead of leaving I just parked there in somewhat isolated spot. The total process (settling and shooting and packing at the end) took me around one hour and a half. During this time there were employees who did pass in front of me and I somehow managed to escape some of them, while HDR technique and merging did the rest of eliminating some of the moving objects that appeared out of control!
The panorama was mainly formed by 3 rows like in normal panoramas with one or two shots for the zenith (but didn't use it later). As for the nadir, it is already a hassle in a regular panorama so imagine shooting this inside a car! I did try, however, to dangle the tripod with the camera and the carrier from the back of the Pajero, but the shots taken were not to be considered "serious"!

A World of Pajero

However, even though it is not a full panorama, the set of images were enough to do some twisting in the projection style as can be seen in A World of Pajero. I think what really helped me here very well in accentuating the colors is using a proper white balance to start with, and this was achieved by using my new Vello white balance disc. From that point, changing colors and vibrancy of colors is, relatively, an easier task.
Even though Pajero 2014 was tone-mapped using Photomatix, yet I find that tone-mapping A World of Pajero using Photoshop CS5 did the job perfectly and with relatively more flexibility than in Photomatix. With the new controls that Adobe provided for tone-mapping HDR images, I think this is becoming a serious candidate and a powerful tool for tone-mapping HDR slides.
I've already printed the flat panorama and prepared it (and signed it) to give it as a gift to the sales person who managed my papers for this car in the nearest opportunity; probably when I go for the first service after 1,500km is passed. This is in a part, can be said to be a "self promoting" somehow, or let's say a free ad. Since I suck at socializing, probably such acts would do me a favor "socially." We'll see about that later...

Nächtlich

Now, there was an idea that I've been trying to do for several weeks but I would always lay lazy or exhausted, or simply the weather and timing wouldn't allow me to. This past week though I had to force myself to work despite some health issues. Seems that the coughing syrup worked on making me drowsy in the first night of the weekend, thus I couldn't do much at night, but the second night I had to push myself despite the persistent coughing. Even though I headed to the location late after midnight, I've encountered some annoying "youngsters" who were not of this country. I somehow got pissed off because at the only time I could be there I must bear with such people. Even though I tried to work silently without paying any attention, I've decided to go back to my car and watch the please until they leave - they seemed to be under drugs or high because of something!

Die Kuwaitische Mitternacht

Guess I've forgot to mention that the destination is the Soog Sharg pier (or dock?) which was a favorite location in the past weeks for long exposures with my Rokinon 8mm fisheye lens. This time, however, the measures are different; I'm doing  panorama and to ensure that the luminance is coherent for the HDR merging later, I have to take 3 bracketed shots, and to ensure that the total time for each shot does not exceed 30 seconds, there is no escape from raising the ISO. Even though it's not something new here but my previous record was to work with a panorama in ISO800. This time, however, it had to be ISO1000! This will have gruesome consequences later on...

Planeta Mitternacht

One of the gruesome consequences of such panorama under such ISO is, naturally, the hardships with the cleaning process and, with highly distorted projections like in Planeta Mitternacht, the noise level becomes even uglier. To clean the image, then, means you must lose details. Thus, so far, these images are for display only and printing them is not something to think of in the current time - unless I find some other workflow to work with these images.

Gravitation

Obviously, the noise level is harsh in shadow areas. There is a noise layer as well in bright areas like the blue sky for example, but they are not as harsh and "ugly" as those in the shadow areas. Probably, I needed even more time for such exposures to expose the shadows properly! But to do this, I would have, properly, spent 2 hours if not more, shooting this panorama.

Schrein Am Meer
The worst to suffer from the noise.

Working at the pier in fact was not even any easier physically than my previous panoramas done back in 2012 on the seashore. Because of the bulky planks and the gaps in between them, clumsiness in movement which I've been known for was NOT allowed! Any loose clutch or grip on any of the tools I've been using (to screw, unscrew...etc) is definitely not an option, and walking must be done carefully in such darkness because my feet can easily trip in between the planks.

Working with these panoramas now did in fact spark some desire within me to work with older panoramas, specially those from Ireland of 2010, from Co. Tipperary. Under the light of the new vision and the new techniques I've learned so far, probably I could make out something different from these old pieces!

I've finally received my shipment here and I had the chance to do a simple test for my new lens, the Rokinon 800mm f/8 Mirror Lens (a.k.a. reflex lens). To use it, I have to connect it to a t-mount adapter specified for EOS system. I was lucky that Vello's T-Mount Adapter comes with a small booklet that gives some idea about connecting the camera to a telescope and other optical devices which gives me some simple guidance of what to expect in the future if I need to do more with my camera.
Source: B&H
I've ordered also a Cokin ring adapter to fix my welding glass in front of the lens (which has a diameter of 105mm), but for some reason the ring came a little! Hence, it is hard to completely fit it into the lens but it did some job after all - even though the situation might be shaky. The other hardship here is the fact that I'm not using a zoom lens, but a "prime" lens. Previously, I used to zoom out to find the object and then zoom into the object (be it the sun or the moon or anything else). Here, though, I have to find my way the hard way, and with this shaky tripod system. Things get even harder with adding teleconverters and raising the focal length up to 3200mm! Anyway, I was able to give it a try.

Sonntag
Rokinon 800mm Mirror lens, f/8, 800-1sec, ISO100.

To add to my "good" luck (and please note the sarcasm), since I got the new lens, I didn't have a good chance to shoot the sun nor the moon because of the clouds and few rains. I did have a single opportunity to shoot at the sun with welding glass, but it seems that the nature (and thickness) of the welding glass is a main reason for defocusing. The shaky system probably makes it harder for me to concentrate my eyes and focus properly (and everything is done manually) but it apparent that focusing with the welding glass is harder. As I'm typing this, I'm waiting for my chance to shoot, this time trying my ND filters (and I do need to use a stack of them). Not sure though if they will fit and cover the diameter of the lens. Another option would be to use the gel filters sheet which I still have, and let them down in front of the lens with the help of the Cokin ring. Just some ideas that I need time to test further. These issues, however, are nothing compared to be having a good and dependable tripod right now which made me think seriously of getting a new one from here.

Finale

Now it is probably the time to slow down and do as much as possible in the same time. Despite the fact that I'm officially diagnosed for retinitis pigmentosa (RP) right now, I'm just trying to chill and cool down my nerves and go on with my life without putting much weight on my own notifications about my own sight.
I had some ideas before in fact about what if I was a sculptor; probably I can make a monument somehow to commemorate RP and its patients.But since I'm a photographer (or let's say trying to be still), maybe then I can show and do something on the same line? What can I do as a memorabilia for this?

I do have some ideas in my pocket right now, but to do them, some effort is needed, specially if I'm working alone and trying to take shots on my own for my own self. I do have some other ideas not related to RP as well and all is scribbled down on sticky notes. Just need the proper "timing" to work with them.

Maybe I can imagine RP to be an inflicted photography style somehow. I'm not sure how this is possible but probably with some thought and philosophy and meditation, I would be able to reach a solution for how to work around RP, and show it in my work.

I'm not sure what I'm awaiting in this life for the time being. My exhausted mind and body are really urging for a vacation somehow but it's unclear how or when. The only thing that I can do for the time being, is just look for some time to sleep, as much as I can...

Es Ist Winter...

What am I? A question that persisted all this week. I'm not sure how to answer it, but to answer this, I have to do some photography. Some more photography, as much as possible. It's winter, with fresh air that would help me clear my mind.
I've been running some errands and will schedule for ERG (Electroretinography) examination. It makes me awry and worrisome. I've read a bit about the test and how it is done and I do feel scared a bit of the way it is done, and annoyed. However, it is something that must be done in addition to the previously-done OCT and Visual Field tests.
I've gave up hope about my (old) car and seems it won't be fixed any time soon. After fixing the computer or chip was fixed, the mechanic said that the car would turn on, but can't be moved as the car doesn't response to the accelertion paddle. I've decided now to get a new car and even if my car gets fixed, probably I would give it up. It will be another drop of money and budget but for something very critical. I didn't decide yet what make of car yet, but it's not a big deal for now.
The nights of winter are lovely and chilling. Fresh air, quiet atmosphere, and sparkles of light. It's a shame though that I can't go out to do some photography every night (and this is one more reason to think of a vacation in winter only), but there is a beginning for everything...

Linien des Lichts
I've talked last week about my desire to go out and shoot, specially at night. This is a must for me in winter time. Winter, is the best season to shoot for many reasons, and for me, it's enough to talk about the temperature. Being cold and out alone in solitude is far better for me than being boiled at night when the soil gives the heat back after a hellish day, like those in summer!

My first trials here were not good but they are a start and I did spend some time reflecting on the results. I was wishing for a cloudy night to do some clouds' movement with long exposures. The target was the dock at Soog Sharg.

Nox Infinita
Rokinon 8mm fisheye, f/8, 4m20s, ISO100.

At the moment I've stepped out of home, I've realized that there are no clouds in the sky to help me. However, it happens that clouds can accumulate on the shores, or specific shores rather than others. I had to try after all. When I reached the place (and it was after 3 A.M.), I've found it busy with some fishermen or just "picnic" takers. I hesitated because I was (and always am) not ready for interference and annoyances, specially from security guys. Thank God, none of that happened. Back to the image now.
I've realized later that the location wasn't good. The fisheye lens did a good job in eliminating the presence of people far from my location, but the light sources made a harsh flare. Such flare might even be hard or impossible to avoid because the sources lie in front of the camera directly I suppose. The f/8 made the effect drastic as well. That, however, didn't stop me from making some few adjustments to Nox Infinita later on, at least to make the color blend nicely with some good contrast. One thing though I wish I've done back then; is to raise the level of the camera which was less than one meter high above the ground (< 3ft).

Unendlicher Nacht
Rokinon 8mm fisheye, f/8, 4m20s, ISO100.

While working with Nox Infinita back home after that night, I suddenly got the urge to transfer the image to B&W. I had some feelings that it would be a nice and a mysterious scene when in B&W (and probably more communicative than the color version); and thus, Unendlicher Nacht was born.
The work with Unendlicher Nacht was harder than I thought in fact. The matter was not a simple matter of adding Black and White layer in Photoshop, or simply changing to Grayscale. Not even as simple as desaturating the image. I had to spend some time changing the tones to reach my own satisfaction with this image. Amazingly, the lines of the stars (or planets) in the sky in the B&W version are clearer and more visible than they are in the colored version. These lines I will talk about later.

Back to the location, I've thought that since there are no clouds to record, the situation and the image was boring already. Since I've brought my LED light with me, I've decided to try and do an experiment with light painting.

My trials are awkward of course because light painting requires special arrangements first. I should have wore black clothes to avoid reflecting light back to the camera. I didn't flip the images when post-processing because they are not serious shooting trials. Another lesson I've learned in these trials, is the importance to time the writing with switching off the light. As you can see from the two examples above, the writing looks more like doodling because the LED was not switched off in between letters.
Back now to the lines in the sky formed by the stars or planets at that location. I have to say it was all discovered by a coincidence, because in fact, I've never thought that such place with relative abundance of light resources would allow the camera to capture any glimpse of the skylines. Let's take a closer look...

Click to Enlarge
Original image: Rokinon 8mm fisheye, f/8, 80sec, ISO400.

In the previous shot I've increased the ISO just to reduce the time to around 80sec, but in comparison, the histogram between those taken at ISO100 and those taken at ISO400 are almost the same; probably the only difference in this case is the length of the lines formed at ISO100 (because it takes 4 minutes and 20 seconds to perform the exposure then). At this point, I do see some hope in this location despite the (usually) inadequate conditions like those light sources and the fear of flare in the image. Add to that, of course, the movement of the active people in this place at 3 A.M.! This tiny discovery about this location, and finding out that B&W rendering do somehow help on accentuating the lines in the sky, makes me eager to do some experiments in the coming days if possible - but this time deeper inside.

Scattered Mind

We had the annual book fair last week and I barely had a chance to go there and get some books. I didn't roam the place and barely visited three corridors of the fair with composed (I guess) most of the Lebanese sector. Most the books I bought this year were from Lebanese publishers. However, I was somehow disappointed because not much innovation is involved. The books are mostly in Arabic, but most of them are translations from foreign books. One would say this is good for people who are not good in English (or French, or even Russian for example) but with me, it doesn't matter. One of the books I'm reading now is How to Think like Leonardo Da Vinci in Arabic (originally by Michael Gelb). However, it is important to read with some critical thinking present. I have to say a lot of the methods and notes written in this book are already done by me naturally (and some of them for unknown reason); Just consider this blog for example where I jot down my thoughts about some stuff in my life (but not much about my emotions like the book states). Moreover, the book seems to give a sense that the western methodology and culture is the base for the rising of a community and its "wake". This is some point that I critically don't agree with, not because I'm from the opposite side of the world, but because I follow up with history and many arousals did exist before the European renaissance. In fact, the European renaissance is the last in the chain so far (and to seal this arousal in culture and science, we had the two world wars with all their push to technology and industrialization) and as life progresses, we are surely to see another link to its chain (as the Chinese are already on the rise). This fact makes me consider Leonardo as a tool rather than an example. Yes, there are many things to be learned in his methodology, but not everything in his methodology should be learned, specially that Leonardo did work under the framework of the European culture back then with all its consequences and shadows over many fields like architecture and music. It seems, to me, the book is mainly dedicated to European audience more than to a universal audience, and this is one negative point in the translation movement. Arab translators seem to be translating without really knowing or understanding the contents of the context in between their hands - it is merely a process to milk money in any possible way. I did even find out many orthographical mistakes in the Arabic context and I didn't reach half of the book yet!

Source: B&H
Anyway, away with Leonardo for now and let's bring more toys into play. In fact, I was hesitating and asking myself if I should do this order now or not. After all, I guess we all have our crazy "momentos". Thus, I had to place a new order at B&H for some stuff that I'm going to list here. The first, and the most important item too, is the Sigma lens of 70-300mm which should replace my broken Tamron. It costs a bit more than the cheap Tamron, but it has an OS system, or Image Stabilizer (IS). It has some good reviews so let's see how it will act. Let's hope I fight the urge to do extreme macro tricks with this one! Good thing that the filter thread is like Tamron's; Ø=62mm. Meaning I can use Cokin's adapter ring already with it for filters. Unlike Tamron though, this telephoto lens, doesn't have a macro mode, which I deem not necessary by now actually.

Source: B&H
Then, I've decided to add a macro rail after the many failures I had while doing extreme macro shots lately and I though this item is a must by now. Compared to other items of the same category, this one rail from Manfrotto is considered cheap! It says that it can be up to 8kg (17.7lb)! Quite good! Ironically though, I should get a new tripod to my collection as well since I do feel my old-by-now heavy tripod is getting chipped and awkward to control by time. However, a tripod can be probably taken from shops around here instead of ordering from outside with the rest even though I'm sure the quality won't be a match.

Source: B&H
Next on the list is another kit for light modifiers. The Impact Syl Arena Strobros On-Camera Flash Light-Modifier Kit is named after one of my favorite authors about Speedlites, Syl Arena. I'm not sure what's the difference between this Impact kit and the other "original" kit, but bearing the name of Syl Arena sounded like it is a recommendation from the author himself! Anyway, I've been struggling for some time with a single set of modifiers and I've realized that I need more modifiers when I work with 2 speedlites. My Rogue kit which I already have, bear a single entity of each modifiers. Thus, in case I decided to use 2 snoots on the two speedlites, for example, then that would be a problem and I have to work around it. Now, it should be no problem I guess!

Source: B&H
One of the ironic thing here is that I've ordered a new camera mount to replace the (crap) Delkin camera vice mount which became dismantled piece by piece with the first or second use. The ironic thing is, once I've placed this order, my brother managed to fix the Delkin vice. Anyway, I'm not sure how good the Delkin vice mount would be after the fixes, so two mounts are better than one. I didn't try the Delkin after the repair until now as I'm typing these words. The Pedco Ultra Clamp Assembly with 1/4"-20 Screw here has a high rating from users on B&H, but I came not to consider much of that. Delkin has a high profile as well and I AM the only one who wrote a negative review about it! Let's wait for its arrival and see how it will manage heavy weights.

 I've always thought of doing shots in strange weather conditions. Well, not strange, but I mean under conditions that usually people try to avoid. For this reason I've longed for having one of those coats for camera systems. The LensCoat RainCoat RS (Rain Sleeve) (Medium, Green) would help me with this from now on, hopefully. I remember one time I had to spend few minutes in the rain waiting for my long exposure to finish. Ordering this sleeve, though, doesn't mean I'm looking for troubles specifically! But it is just something useful and good to have with you in winter specifically.


Source: B&H
Finally on the list, I've placed an order for Vello Universal White Balance Handheld Disc. I've felt that I need such a tool specifically when working at night time in locations that bear lot of lights of different types. It does indeed make a difference when trying to fix all that in post-processing. The disc here is handheld and I think it is what I need - it doesn't screw to the lens like other WB tools available and it is up to 95mm in diameter. Thus, I can use it with many lenses now and in the future without worrying about the filter thread on the lens itself. The thing I'm not sure of yet though is whether I should take a shot of the disc with the same ISO as my original exposure or not. In my camera (EOS 7D) all I need is to take a shot of the body that I want it to be a reference for the WB, and then use it by Custom WB function. Does the ISO make a difference? Theoretically, it should not. We'll see!

Finale
Books, tools, camera, lenses and even artificial languages... where am I and what I'm doing? It's a weird feeling inside me; it's like hope and despair entwined together. There are lot of things I want to do, yet, something is stopping me. Well, beside the physical condition that is. At work now, more issues are awaiting and I must tend to them, beside doing my own business with the eye-checkups and Mom dialysis schedule. As much as I want to keep feeling strong, yet I can't neglect that feeling inside me; a feeling of betrayal somehow. Like someone had been left all alone by life, despite all the good things that I've been trying to achieve to others. I wonder if this is what they call midlife crisis.

Now, with my ideas for getting new toys, and new car as well, I do hope that my mind is taken off a bit from such melancholic thoughts for some time and get busy with other creative projects. With my new car (if I get to purchase it any time soon), I would be free to go to Failaka island some time, at least for few hours if possible. On the other hand, and because of the retinitis pigmentosa possibilities, I've decided to dig out for solutions for my brother, sister and me personally. I'm so sick of life right now in fact that I'm challenging it not because I like living it - there is nothing much for me here, but merely because I hate it, and if it was a man I would have strangled it to death. Thus, I want to do everything I can and RP won't stop me right now. I want to keep looking and doing everything I can do and reach with my ideas. One step at a time... and all alone.
