Participating in a P52 or a P365 can be very rewarding; I did a 365 a few years ago. Shooting regularly, often with some parameters and themes in place, is a great way to really learn your camera and increase your skillset.
Just as important, in my opinion, is seeking out feedback about the work you are producing. Shooting volume doesn't achieve much if you don't know if it's any good. Find someone whose work you admire and ask them to critique your work:
- Are the colors accurate? (If there are people in your image, are they people colored, not blue or magenta or orange?)
- Have I chopped off anything important on the edges of the frame?
- Is my focus in the right spot and sharp?
- Is my exposure right for the subject?
- Do I have any areas that are blown (too bright) or clipped (too dark?)
- Have I successfully told an intentional story?
- Is my depth of field (aperture choice) the right one for this photo?
I would suggest you do this along side a P52 if you decide to do one. You don't need to pay for a formal mentor, and you don't need to get feedback on every image. But in order to grow, we have to know where to improve. So be sure to find someone you trust, and then listen with open ears when they tell you where you can make improvements. If you can develop a relationship like this, you will grow far faster than any other method, in my experience. And also be sure not to take whatever criticisms that you are given personally; we all started somewhere, and we all still have room to grow. I'm pretty sure we even have a CC thread in this forum pinned, although it hasn't been active in awhile.
