The trouble with employing a photographer as i have done in the past although most of the shots were really good there are small things that i see in the shots that the photographer wouldnt just because i know the jewellery and how it should appear, for example i had some shots of a nose ring which most people choose the smallest size of but in the picture it looks large and thick and just didnt look right even though it was a great shot, nice angle and showed the detail of the piece so i would like to be able to put my own mark on my product shots if that makes sense.
OK, so that means you are not employing a very good photographer. A true professional photographer will go through every little aspect with you and shoot exactly how you want.
Find out the style, angles, market you are going for.
There are many different options, even remotely where you'd be able to see images and preview and discuss how you want things, if thats not exactly how you want it.
I've worked with dozens upon dozens of clients who have a very specific vision, and some are actually not that good at communicating across that exact vision they have, so we work together, effectively they become the stylist, and sometimes I even work with a stylist
and the client, that way the stylist does their job, but the client still has the final say.
So if the client wants to add 'thats good, but I want to show that aspect' then the stylist can adjust it.
Or if the client wants to add 'I like the angle now, but the stone isn't lit correct, I really need to be able to see the facets' then thats where I'd come in and tweak the lighting.
Its a really fast way of working, and the client always ends up happy.
To be honest from experience I've shot countless numbers products, and thousands of pieces of jewellery. Jewellery is particularly tricky. I generally need a pretty complex lighting setup and it has to constantly change and be adjusted between different pieces. Different setups for different metals, stones, facets, clusters, plus of course a total change of setup between bracelets, rings, pendants etc.
