Aberration, Color Fringing

posted on 16th of august, 2011

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. This process results in a balanced, clear and sharp image on the resulting photo. However, when this process doesn’t occur, aberration distorts the color and clarity of the original image, ruining the resulting pictures. Often, the edges of the pictures are the most distorted areas....

That's a very informative article and link! Thank you for sharing that. Since DT seems to frown on chromatic aberration, I do my best to inspect and get rid of it if possible. Lightroom does a great job of this most of the time.

Panning, The Art Of Motion Photography!

posted on 17th of august, 2011

Panning is an interesting art of photography. It has been there since ages but it still excites many photographers. It gives the right feel of motion to your pictures. Panning works best for sports and motion photography or when you want to depict a motion or movement in your subject while keeping it sharp and focused.

Panning basically means you click the picture of a moving subject while you move your camera with the subject. You get the subject clear but the background is blurred. For this experiment with the following settings:

- Set your camera on a slow shutter speed like 1/40 or 1/30. You need the slow shutter speed as you need the blurred background.

- Stand on the side of the road (best place to practice with the moving traffic). Decide on a point...

just love the picture of the dog. the other one is photoshop all the way, no panning technic there! About the speed settings, no sure if you can set a speed as a tip, you are inducing others to error. The simple example of that, is that you shot the dog at 1/1000th with f7.1 and iso 800, so there are no rules for speed, just go with the light avaliable and the speed of your subject. a moving turtle will require a very different setting than a rocket missile!

About me

Photography was always my favorite hobby, but my romance with microstock photography really began when I joined Dreamstime. I felt like it was the right place to build a career out of my hobby and I was right. Dreamstime is more like a school rather than a microstock agency. If you're a newbie, then it is here where you'll learn all about microstock.
