I just read a lot of online tutorials for photography and photoshop and spend a lot of time looking at other photographers work and learn from that. Now that I'm working out the technical aspects of photography I have found that the quality of my work has improved. I'm also able to look at a photo and work out what sort of apeture was used, how it was lit (eg: natural, flash or other lighting), I look not only at the subject but everything around the subject. I take particular note of what the first thing to grab me when I see a photo is and then work out why it grabbed me.
