Welcome to CS
You have a nice cat there. This is a good start.
1 important thing is, try not to use direct flash on them. Also try not to take random shots, plan your shots.
The 2nd photo is slightly under.
Well, remember to read your camera's manual, keep shooting & continue to post your cat shots here. If you have questions on how to take better cat pictures, just ask. I'm sure many CS'sers here are willing to share.
Oh, one more thing, leave space between your photos please number your photos
Yes, slight underexposedwhat do you mean by under? under expose is it?
noted. this is a new picture that i took not long ago.Yes, slight underexposed
Don't worry about the resolution.i think my image resolution is too big. anyway i can reduce to enhance the viewers experience in the forum?
ok. means i should just let auto-focus do its job? or use live-view?Don't worry about the resolution.
Most of the shots on this set is not well focused & #7 is under.
Concentrate on your composition, focusing & exposure. You have a cat at home, you can take all the time you can to get some good shots, unlike us we have to chase & stalk cats on the streets.
Take your time to shoot & don't shoot just for the sake of shooting
Auto-focus or manual focus is up to you. Whichever one you use, make sure your shots are in focus. Same for live-view. My personal preference is view finderok. means i should just let auto-focus do its job? or use live-view?
Once you've shot eenough and understood how iso aperature and shutter speed affect exposure and how aperature and focal length affect the DOF, you should look into gettting a cheap fast prime like a 50/1.8 for the fast aperature and shalow dof for subject isoaltion.
