Hi Jeanette, I just had a look at your gallery. I particularly like the first one you posted, of the Retzer Nature Centre, and also the Snail Shell Harbor (I like it as it is). The waterfalls are great too - you have loads of choice. You have to go for it - you know in your heart the one that means most to YOU.
I had an exhibition last year of ten prints. It was very scary, - but when the picture is actually up, it will be great, believe me.
BTW that thing about spots of dust under the glass resonates - but at the same time don't drive yourself mad with it; learn also to call it a day; be proud of what you've done..
If it's framed and there's a spec of dust after closing it up... you open it and get rid of it. Clean the glass. Things like that people viewing it probably won't notice, but you will and you'll worry to boot!
But thre's always ONE more bit of dust. No matter how clean you think it is, a bit always gets in there at the last minute.
When I was at the Aperture 50 Exhibition earlier in the year, I spotted a HAIR under the glass of one photo... Made me feel a lot better to know that the pro's have trouble too.
