Ok I'm back!
As Fran says cropping is a good way of just framing the part of the photo you want, it really acts and enlarger. When you crop do NOT reduce the size of the pic first, crop it straight from the camera, when you crop you lose resolution, so the picture will become poorer quality. I try to fill the frame with just the subject (in animal cases) that then will make it better for printing, same as before, higher resolution without the need for cropping.
For action type shots, use the "sports" setting on your camera, I tend to use manual settings, but on compacts and some DSLR's you do have a sports setting so use this for everything moving, it increases the shutter speed and "freezes" the action. Here are a couple of examples of dogs taken on the sports setting.
If I had used a normal setting or one with a slower shutter speed, such as "scenery" the dogs would of been very blurred.
I take portrait pics for clients dogs, with these I always try to fill the frame, because I print them for the owners. I do head studies as a rule, but have done body shots aswell. I use the "portrait" setting, it gives the background a blurred look and therefore keeps the focus and attention of the camera on the subject alone. For indoor shots and flashes you do get problems, using a red eye reducer can help, but it usually releases a series of flashes which is supposed to make the pupils contract, yes it does, but by that time the Cat has its eyes shut! Try the auto setting, or if you can turn off the flash use that, or even try putting something over the flash AFTER you have focused, keeping your finger on the button, sometimes this does work. One other thing is you could try not getting the Cat to look directly into the camera. These are a few pics I have done of clients dogs, taken on the portrait setting.
I also try to have an uncluttered background, again keeps the focus on the subject. The pic of the pup was taken in someones arms, note the red jumper!
I hope that may help a bit, please ask if you want to know anything else, I am not by any stretch of the imagination an expert, but I'll help if I can.
FRAN.
I will install the software I got with the camera later today and see if I can see how to reduce pic size for you using it.
