Competitions are good in camera clubs up to a point. They do help you to iron out common faults found as a beginner. The presentation of you work can be improved by seeing other peoples work. You can also learn B&W film development and use the club's darkroom until you can set up your own. These are just some of the positives in belonging to a club. I do know that there are a lot of faults to be found there also. But then nothing is perfect.
