Here are a few tips:
If using a zoom or if your a bit shakey as I am use a tripod. There are some very small table top type tripods that can be used that dont take up a lot of room in your blind bag.
When shooting pictures of your days take dont do it in your driveway or the concrete of the launch. try and find a nice background such as some nice grass by the launch or trees in the background. Take a few seconds to wipe the blood from your kill or pose it so that the minimal amount of blood is visible. Push the tongue back into that dead deers mouth. You get the idea. Taking these extra steps will make the picture that much more appealing and one that you can share with others. Nothing will put off non-hunters than to see blood and guts all over the picture.
For cameras that require adjustments to the aperature or speed like the older SLR's or the newer high end digitals. Try bracketing your shots, take a picture one f stop higher and one lower than what the cameras meter tells you. This will allow a difference in the depth of field and the result maybe a picture that shows a little more detail or is just more appealing. You cant tell much from a 1.2" LCD display on the back of a digital camera so you should try some different settings once in awhile you'll be surprised at the results.
Dont forget that even the point and shoot digitals have the capability of zoom. Try zooming in a little doing this takes away some of the background and makes the shot more interesting at times.
Remember in outdoor photography you want the viewers eye to be drawn to the subject. sometimes a branch in the foreground will draw the eye to the subject your photographing.
Most importantly read your manual if you have one! If your serious about taking quality pictures do some research, read about it, browse the magazines. Look at photgraphs by others and get ideas from them. Their are a few very good photographers here on the site look at how they compose their shots. Steve for one has a very good eye and composes his shots well.
Take lots of pictures! Professional photographers will take hundreds of shots just to get that one special one.
