    I think Brian Peterson in his book "Understanding Exposure" says it well. To paraphrase: Sometimes the photographer wants to tell a story with a beginning, a middle and an end. That calls for narrow apertures and large depth of field. Other times the photographer is looking for a singular theme and uses wide open lenses and very narrow DOF to block distractions. Finally there are times when the photographer doesn't care -- the "f/8 and be there" mantra of old news photographers.

    All three methods have their place.

    There is no rule that says you have to like what the photographer produces.

    That's true enough. So is it just me, or are F/22 apertures unavailable on digital cameras?

    Tom, given the very short focal length of these lenses, the small size of an f/22 aperture would probably cause severe diffraction problems. Plus, with lenses of those focal lengths, you don't need f/22 for great depth of field. You get it with f/8.

    I'm not getting it with f/8. That's the problem.

    Depends upon the camera, or more properly, the lens and sensor size. A P&S with a 1/3 sensor and a lens focal length of 6 mm will have the same view and DOF as a 35 mm full frame with a 43 mm lens at an aperture of f/29. Those numbers are from the calculator about half way down on this page [cambridgeincolour.com].

    f/22 is available on the lens I usually have attached to my Canon digital SLR. However, on that camera an f/16 is the rough equivalent to a 35mm full frame f/22.

    What size sensor? EF or EF-S lens?

    I s'pose this topic should be in it's own thread... I'll start a new thread later.

    Sure. In the mean while... Canon 7D (replaced a Rebel Xt) with a 1.6 sensor.

    EF-S 10-22 f/3.5-4.5 USM goes to f/22, f/29 at the narrow end.
    EF-s 17-85 f/4-5.6 IS USM goes to f/22, f/32 at the narrow end.
    EF 24-70 f/2.8L USM goes to f/22
    EF 70-200 f/4L IS USM goes to f/32

    The 17-85 and Rebel Xt are on the shelf, waiting for my wife to make up her mind if she wants to use a big, heavy SLR or stick to her P&S.

    Where is everybody?

    The last post has been up since about this time on 3/3, two days?

    I have been posting since this started and I don't think it has gone two days for a long time. Lets' go!

    Why yes I do

    I think I was having PDD (posting disorder disease). Sorry.

    No need to apologize. Your request for action made me take the time to actually look for something appropriate that I'd not posted before. If nothing else it was a good excuse to peruse some of those dark corners in the photo library where I don't go much, any more. Thanks!

    Gail. Your post #5206 is very interesting! Where was it taken and what is the story behind the building? Thanks.

    Thanks! It's been an adventure.
    When I saw Gail's image it made think "That's how I see mine"

    That porch landing support on the right isn't attached.
    I was looking at some options and it's just a stray 4 x 4 leaning against the wall.
