That was very good Whiskers. When I take a picture I try to follow some of these rules. In my mind I draw a tic tac toe on the picture I'm taking. When the lines intersect that;s where the subject of the picture should be. If it's a person they should be looking into the bigger part of the picture and not looking off the picture. Then there are some pictures you just want to document what you see. Also you can go into PB and recrop the picture to correct it. Here's my example. The hummingbird is in the upper right and looking to the left and into the the picture. Also note the nectar is in the opposite cross hair.
I belonged to a couple camera clubs and we had slide competitions. When they were judged by a third party they would critique the pictures, good or bad. So you would learn from other peoples pictures too. One was a small club and one was a large club. The competitions weren't easy. But because there were so many people in the club you only competed with the people at the lower level. the pictures were either accepted or not accepted. The more you got accepted you would move up to the next level. You could only enter 4 slides in each competition. But they had three categories, pictorial, nature and photo journalism. Pictorial could be anything in the world. Nature was tough because it couldn't be just any flower. It couldn't be one that you raised in the garden, that isn't nature. A picture of fungi on a stump...no good if you could see the tree was cut down. But you learned a lot as you went along. It was fun and educational. If you asked anyone how they took a picture they would tell you every detail. My goal was to break a rule and still get a picture acceped.
There is one type picture that I will never understand. People will take a picture of another person. They put there head right in the middle so there is a lot of empty space about them and then cut off their feet. I never liked that even when I knew nothing about photography. I see a lot of older pictures like that.
I've just started doing a fortnightly U3A digital photography course. The chap doing it is a very experienced photographer,but so far all he's done is talk us through an online course on the technical aspects. Most of it's gone right over my head.
Next time though,we've all got to bring in half a dozen photos and comment on each other's. I am so not looking forward to it !
