I just wanted to share this video from Photographer & Author Harold Davis on how he shoots and processes his beautiful translucent flower photos: Creative Floral Photography with Harold Davis .

It is quite an old technique, before digital it meant capturing two exposures on a single frame of film. But with today's modern cameras and software, creating a good double exposure image is much easier.
The Droste effect is the name given to the effect when a picture appears within a picture of itself.
It is named after a brand of Dutch Cocoa powder, whose box featured an image of a woman holding a tray with a cup of cocoa and the same box with the same image on it.
The infinite recursion of the Droste effect is an unusual technique, but can produce some great images. In this article I'll look at how to create two different versions of the effect - the frame within a frame technique, and the spiral technique.
Chromatic Aberration can be seen as color fringes, most noticeable near the edge of an image. This is caused by different wavelengths (colors) of light being focused at different points.
In the image above you can see chromatic aberration - a green fringe on the left of the leaves, and a magenta fringe on the right.
This happens because lenses have a different refractive index for different wavelengths of light. So as the light passes through the lens, it can become split, like it does through a prism. The problem is only relatively small, but it can show up in images, particularly if you view them at large sizes.
