It always amazes me how you (and others) remember in what order things occur--looking for beetles when the black hollyhock blooms, indeed! I, too, have a problem with getting my point-and-shoot camera to focus at the correct distance. Manual focus is difficult for those of us with visual problems, but it beats auto-focus in some circumstances. It is even possible that some point-and-shoot cameras have a setting that allows one to focus; but, who ever really learns all of the camera capabilities?

Beautiful, beautiful flowers. We had over an inch of rain two or three days ago and it has rained, some, yesterday (morning) and this morning. I'm thinking sharing, even if it isn't being received up there.

A true "point and shoot" has a deep "depth-of-focus" and won't pinpoint a focul point. Most automatics "home" in on the "closest" object in the frame.
If your digital camera has a manual mode, use it and look at the LCD display to focus instead of the view-finder.
Works for me. Tri-foculs made me park my 35mm's years ago.

WD--Thank you for the input. Depth of field made the old fixed-focus Brownie box cameras work pretty well.

My hp camera has but one place for me to look at the scene that I'm shooting, so maybe I'm missing something; but, I can guarantee from looking at many out-of-focus photos that my camera does not focus on the nearest object. It tries to focus on what is central to the scene--tricky if I want to focus on a thin something. There is a means of tricking my camera--of showing it what I want it to focus on--and I can get it to work, sometimes. Most of the time, the light is bright enough that I cannot see the display well enough to pre-set the focus. Oh, well.

I haven't been able to use a manual focus for anything, so don't have a manual focus camera.

My camera has 3 focus lengths; Macro, Regular and Infinity. It does not always try for the closest object, but I have not figured out the magic formula for why it picks what it does (it does have a "face finder", but since I rarely take pics of people, that is not very helpful for this discussion.

Oh, I think I can also get it to focus on something the same distance as the object I am trying to photograph, then telling it to keep that distance. That would be great if I could tell relative distances, but I suck at that.

At least I can wipe out the pictures that don't come out the way I planned!

Bogie said it better in explaining how focus is achieved on my camera--not by showing it what to focus on, but by setting it to focus on something that is the same distance away. Since, most of my photos are taken out-of-doors when the light overwhelms the viewing window, the point is moot--I cannot see and just blindly "point and shoot".

on a slightly different note bogie, i think we had all your rain for july last week!

Bogie, may I ask what model of camera you have? Getting the autofocus to focus where you want instead of where it wants is possible on some cameras, but it depends heavily on the specific camera in question. Cheap cameras usually can't do it, but the higher up the performance scale you move, the more likely it is to have that ability. Some of the superzoom cameras, a.k.a. 'pseudo-SLRs,' have multiple focusing spots and multiple focusing modes, which would probably let you get that robin's nest and any similar subject.

Wolfwalker - I am using a fairly cheap camera: a cannon Powershot SD1000, so I am probably out of luck.
