I have noticed that in my Canon 500D, the depth-of-field preview in the optical viewfinder is inaccurate with large aperture settings. If I press the DoF preview button, there is very little ...
I just purchased a Sigma 10-20mm lens (Canon mount) and based on the reviews I was aware that many people receive copies of the lens that are soft or don't focus properly. I purchased from B&H, so ...
I was flicking through some photos on flickr and started thinking that I wanted to achieve a particular effect - after a bit research I found that what I was appreciating was Depth of Field. Subject ...
I have read about difficulties getting focusing right when using a large aperature (because of depth-of-field issues). If I am using a fast prime wide open (say F1.4 or F1.8) to shoot a target in ...
what is the mechanical explanations as to why some cameras can take good bokeh and not others. do lenses have a role too?
I don't know how it's achieved or what it's called, but occasionally in a movie I see an effect in which the perspective of the scene is modified in such a way that the objects that are further away ...

What are the best practices for DOF stacking? How do you get the frames with focus just right amount apart? How do you stack them in post processing?
I'd like a clear & easy-to-understand (especially for non-physics-types) explanation of what Hyperfocal Distance is, how it affects photographs, and what determines its value.
How does aperture affect my photographs? Why should I care about the aperture with which a photo was taken?
I'm curious about how my "area of acceptable focus" changes when the focal length of the lens I'm using changes as I zoom (or switch lenses). In particular, I'd like to know how the front & back ...
I have a compact digital camera, and in macro mode I can manage to achieve a blurred background, if the background is far enough away. Can this be done when taking non-macro pictures, and if not, is ...
I know that this effect occurs when there's a shallow depth of field. My question is, what are the various ways I can increase this effect in my photos when I'm taking them? Note that I'm not ...
