Anyway, there had been some good news around and some more experimenting with my camera as I'm feeling more free and out of my obligations. Yet, I'm trying to find the power and time to work on some projects.
One of the projects I've started to experiment with here is the usage of my idle pinhole camera cap from Rising, which I've used only twice previously before this time. Now, I'm trying to get used to it and trying to be more creative about it, specially with its fuzzy and blurred images.
|Rising Standard Pinhole|
According to the Specs mentioned for this pinhole (one of two types), it states that it is 0.22mm in size with f-number of f/222. However, I'm not sure how it was calculated since according to my own investigation here, this should be f/200, because the focal length or the distance from the mount to the sensor (a.k.a. flange distance) for EF and EF-S mounts is 44mm, and calculating the f-number using the relation: N=f/d yields 200, and not 222!

Away from calculations what is supposed to be or not to be, I've managed to try it out and I really like some aspects about using a pinhole, specially when it comes to the flare as seen in Visionem Infirmus. Lot of people think those are light bulbs, but they are candles actually (long and short ones). Because of the perfect circle of the aperture here, the flare is more pleasant it seems and provided such a halo effect; How I wish my regular lenses would do the same! While doing Visionem Infirmus, I didn't really know what I'm doing exactly, it was a random setup just to test this pinhole. There is a mystic feel to it after all (probably because of the talisman too).

Calculations-wise, there might be a hope to create something sharp, or at least sharper than usual, if I just find a way to nudge the pinhole cap for about 5mm forward (or to be precise even further, for 4.8mm). Taking images with my Canon EOS 7D with a manual lens (e.g. Rokinon 8mm f/3.5 fisheye) or like this pinhole, it rigesters the value of 50mm as the default focal length of the camera, which I have to consider as the real focal length. However, my previous work with macro photography and shooting into the microscope, made it clear that the flange distance (or distance from sensor to the mount) which is supposed to be the pinhole focal length is indeed 44mm (all my calculations for the magnification ratios were based on 44mm and shown correct in practice). Mirrorless cameras do have a shorter focal length by the very nature of their design, but they might be more appropriate for pinholes because of this shorter focal length under the light of the relation: d=2√(fλ); where "d" is the diameter of the pinhole, "f" is the focal length, and (λ) is the wavelength of the light (typically fixed at 550nm). With some algebra here and solving for (f), it seems the proper focal length for 0.22mm pinhole would be 22mm. As far as I know, Canon's mirrorless cameras have 18mm flange distance; close.
Meanwhile, I'm expanding my experiment with the pinhole further to my converted Canon EOS 7D, as I'm trying various filters with the pinhole (taping it on the top of the pinhole). Pinholes though, under the light of the formula mentioned above, can be quite sensitive to the wavelength under inspection. However, thinking about it, it seems this is my only hope to get a proper UV image; since most of the lenses I have are coated with Anti-UV protective layer and might not be blocking essential wavelengths in UV range. Thus, I'm set to try this out soon (and of course using a hot mirror to block IR over my UV B+W 403 filter). Pinholes, of course, do not have coatings and thus might be the only way for me right now to shoot decent UV despite the fuzzy image I'm going to get.
Dream Coming True
For about a month or so I've been going around and trying to find a way to get a permit to shoot some pictures inside a theater. Not any theater. It is a theater that bears a memorial for the Giant of Kuwaiti acting field, AbdulHussain AbdulRidha, who passed on August 11th, and we are still mourning him almost every day since then. A rare man who witnessed the rise of this country, as well as its changes from old to modern (and not to say I do like the modern). The significance of this work is that, I dreamed about it, and it came true indeed. I couldn't apply some ideas I had in my mind prior to the work but at least I've done a masterpiece panorama for this memorial.

The Smile Giver and Pride of My Homeland.
First of all, I paid a visit once I got a phone call that I can go into the place. This visit is to set some ideas straight and a get proper vision for the place. In fact, I once thought that there are two paintings: a mural and a portraiture painting. However, later I've discovered that it is actually one painting, and it is the mural that everyone was talking about. The mural or painting is a masterpiece painted by the artist Ahmad Muqeem. Not sure about its dimensions, but the height of the painting is surely somewhere beyond 2 meters (~ 6ft) and the width is around 2 meters as well. This changed some of my ideas as I was planning to pick my brother and make him read Quran in front of the mural, but since it is elevated off the ground, I think it won't be of much use here (or it might in fact but I didn't think that way back then). My main focus was the panorama.

Of course I wouldn't pass the chance of creating a VR out of this panorama. Moreover, I think I will adapt to the practice of uploading my panoramas to 360Cities and get an embed link for my blog here. This way I can avoid many plugins issues I guess and they provide further options to view the VR as well. Unless the VR is not significant, I might upload it the old way (spawning the file somewhere and embedding the link here).

A good thing here is that 360Cities provides the option for viewing the VR with VR goggles (on smart devices) which enables the viewer to roam the place by moving his head (or the device that is) around instead of being static and roaming the place by the controls.
If you are reading this and do enjoy VRs, I'm asking you to, please, Like it and share it with people you know. Unlike the rest of my panoramas, this is a work and a job I'm proud of, as a tribute to a personality that means so much to me, personally. Thank you.
Well, I feel like a bulk of load is removed off my shoulders. Some issues at work are finally done for good, and I've finished the panorama that I've always wished to do, I think now it is time to dream a bit again and think of something else to do. I do have some ideas to experiment with, like the pinhole and UV photography, beside some other ideas of "regular" photography. The problem though, as usual, time, and further more, the need for help (from my brother mainly who has other responsibilities). I think detaching myself a bit from the photo-club which I'm part of did give me further motivation and time to try out my camera. Probably I'm the type of photographers who cannot work in a team and rather establish himself alone. Anyway, time to post this, and go on dreaming, again…
