    Working With ADEP Setting



    I'm still struggling with, but enjoying, learning DOF calculations. My end results have yet to be satisfactory but, for me, at least, learning is as much fun as doing.


    Recently I started experimenting with the ADEP setting on my 30D and have been fairly pleased with the results.


    Any comments or suggestions regarding this?

    Re: Working With ADEP Setting



    my only advice is to not use ADEP. I've used it a few times and always found it easier to use Av mode and aperture narrow when I know I need wide DOF and use a wide aperture when I know I need a fast shutter speed.


    I suppose that I'm just an anti-automatic mode kind of guy. I use exclusivly Aperture Priority and Manual modes. At least then when it doesn't come out like I want i know how to change it, rather than hopeing ADEP gets it right next time.

    I've shied away from
    the A-DEP mode ever since doing a science project on depth-of-field for school.
    The basis for measuring depth-of-field is known as the Circle of Confusion
    (CoC). In Canon's EF Lens Work II, they state that they used a 0.035mm
    CoC for EF lenses. That's fine, until you print larger than 5x7, since they
    assume that the average photo will only be enlarged 5x over the size of the
    negative/sensor (35mm/full-frame). Thus, I assumed that they used the same math
    for A-DEP, so I've left the mode alone, although it will do a fine job with
    fairly small prints.



    There are some handy depth-of-field calculators online that
    allow you to set your own CoC*.
