Criticism is OPINION. Some criticism is of more value than other. A critique of photographic work from a novice, is less valuable that criticism from a source of great experience and education. Criticism from experts can be very valuable, and thought provoking. Criticisms are opinions, and like that perticular body orifice..."everybodys got one". If you can't stand criticism then don't show your work or ask for opinions. If hungry for growth...show your work to somone with experience and talent...and get constructive feed back. Any critic worth his/her salt, will give an opinion in a positive and constructive way, to help the artist improve with out destroying the artists ego and self esteem. Remember that self esteem comes from 'self'. It it comes from critics or others, it would be caller "other esteem"! A critiqe of ones' work from a respected artist, can be a learning, positive and growth experience. For those with thin skins.....and fragile egos,...don't bother. Just shoot for yourself, and be happy in your work. No sin in that.
