I'm relatively new to photography as far as playing with apertures, exposures and settings goes. Although I'm comfortable with the theory, I seem to be constantly having trouble with my photos, particularly getting images.
I have a 40D with a EFS 17-55mm F2.8 USM IS , which I understand is a reasonable combination for someone of my limited experience.
I primarily kick around wetlands and lakes, and mostly take photos of plants, wide angle landscapes and the occasional animal.
I generally flick between the automatic settings and Av ( priority?) when taking photos, and normally leave the auto focus and IS on. In most cases, I can see why many of my dodgey photos have not worked, ie, too low F setting, incorrect selection etc.
One thing that has concerned me is that my photos seem to lack focal when I bring them up to 100% resolution on my computer. This is particularly the case for vegetation shots and landscapes.
I'm not sure whether I'm expecting too much from my camera combination, whether my camera settings are constantly wrong or whether my is dicky. When I use the flash, most of my closeup photos turn out reasonably , indicating that it is likely to be me that is the problem.
I've pasted a number of photos below to illustrate my problem. I've read a number of other posts which have mentioned calibrating the camera and , but I'm not whether this is the reason for my lack of . The photos taken using the flash tend to be reasonably focused which suggests that it must be something that I'm doing which is mucking up my photos.
F16 1/25 ISO200 - sunny conditions, lizard head not
F7.1 1/400 ISO400 - overcast but bright
F8 1/500 ISO400 - overcast
I would be very appreciative of any suggestions. I'll post a couple more photos later when I have a bit more time.
