Blimey... what a big word-count, just to create the ground-rules for a critique!
The first time I showed my photos to a 'proper' photographer (Martin Parr), he said they were "snapshots". And, you know what, he was right. Family and friends had gushed over my pix - this was a long time ago - but that 's what family and friends
do.
As to people not being 'qualified' to offer criticism, I'm not even sure what this means. If I was, say, trying to choose a dozen pix for a calendar, or a series of postcards, I'd want to get some feedback... but from the kind of people who buy calendars and cards, not other photographers!
One of my favourite expressions is "you don't have to be a carpenter to recognise a good table", and it seems applicable here. I'll accept criticism - from anybody - and I'll try to take something of value from every one (even the unkind ones). I sell pix as stock, so the bottom line, for me, is someone choosing to license one of my pix rather than someone else's.
