What are best photo editing techniques for a iPhone user?

Best techniques is to be very conservative with your editing. By far, the biggest mistake is applying too many filters or too strong of an effect. Limit yourself to just the basics: brightness, contrast and color correction.

Always keep an unedited version of your photos. What you do today to your photos may not be something that you like tomorrow. I've got a bunch of images taken several years ago that I just cringe when I look at just how bad of an editing job that I had done. Thankfully, I have backups of all of my images so that I can go back and redo things as my tastes and skills improve.
