Distortion, distortion, lens distortion

I nerve thought that this kind of effect impacts my picture. I thought that the image distortion exists only for the very fist digital camera like Olympia Camedia 800L that I bought more that 15 years ago.It is still exists. Not so obvious but It can be notice when you come to the landscape or cityscape photographies. It can be seen with the lines, parallels. It make your picture having something weird or not real. For exemple: your horizon is not flat. your buildings are bulky. your cube are... continue reading

Aberration, Color Fringing

Aberration, also known as “color fringing,” refers to the effect in which light passing through a lens becomes blurred and produces a fuzzy image on the film. If the camera lens is unable to focus light of different wavelengths or if the lens is scratched or otherwise damaged, chromatic aberration of the final image will occur.In a normal lens where aberration doesn’t occur, the lens directs light of different wavelengths to specific areas of the film, depending on the particular wavelength.... continue reading

Relational Distortion

Lately I have been reading a lot of music recording, arranging and mastering stuff apart, from the regular photography and editing. There is an exceptional relativity that I found in between not just in the technicalities of these two arts, but also in real life.Everyone who is aware of digital photographs generally is aware that when we zoom the pictures we reach a level where we start seeing pixels (squares) in the image. This distortion happens due to excess dissection of the image beyond... continue reading

Pro-optic 8mm f/3.5 fisheye

Here is my first image approved with a new lens, the Pro-optic 8mm f/3.5 fisheye.It is a remarkable lens in a few regards:1. Price.At $250 this lens is almost as cheap as the nifty fifty, yet adds a view to your kit that is impossible to achieve otherwise.2. Solid build.Surprisingly, it is well built.Nothing wobbles.3. Manual controls.At first this seems a shame, but with a fisheye you really can't focus by eye anyways - just a quick glance at the distance scale and you are in business.... continue reading

Scans from Dia

Recently I gave some of my old dias (24x36mm and 6x9cm) to a professional scanning service that has good references. The scans were made with an up-to-date Nikon scanner at 4000 dpi and saved in maximum quality JPG (12).DT refused most of these scans and told me, that there were distorted pixels. As I looked more closely at the images I found that DT was right and the question emerged what to do against this loss of quality. Do you have some tips for me?Best regardscristalloidPS: I do... continue reading

Time is Relative

Yeah! I finally got an image accepted for Assignment!This image was created via layering multiple exposures of a clock ticking, with each shot taken 1 sec apart, coinciding exactly with the second hand arriving at the mark.These multiple images were then layered in Photoshop with each succeeding layer's opacity a constant fraction less than the previous one. In this case I think I used 75%.But such layering would not work if not for Photoshop CS3 new Auto Align Layers by Content, which... continue reading
