- Find an interesting subject - and the lens and the camera and the grain and the noise just don't matter, is the photo fun to look at? The only thing that can get annoying is bad focus and camera shake.
- All subjects are interesting - when looked at in your unique way. Find what you like and bring that into all the photos. It will take all your life and will change as you change, which is why art is such a good hobby.
- You can always crop more - people have fleeting expressions, you need to shoot NOW. Don't worry about exact framing, just make sure you get all you want in the frame, crop out the bad parts later.
- Someone somewhere has taken a better photograph of that - just look through flickr. Concentrate on having fun. And make sure you experiment and come up with your own way of looking at things.
Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or...
