Hello, I am quite new to photography and new to this site too. I hope I can develop my photography skills through this site. I use Nikon D5000 (borrowed from my sister's friend) to capture some great moments and I'll get myself a DSLR camera soon after I graduate. And I have some issues about photo editing. Before I begin, I'll be honest here that actually I had a minor eyesight problem a few weeks ago but now it's getting better. so yesterday I took some pictures and it seemed quite fine when I looked at my camera display screen but when I display on my laptop most of it are either blurred or out of focus (probably due to my eyesight problem or maybe my photography skills turned rusty or maybe both, ugh). I use Gimp software but it doesn't seem to work (plus I also not familiar with it too). Can anyone help me out for this? Thanks a lot!
