I'm not sure anything I add will be of much value added
. I do know lots about frames and making them. In the middle ages when I was a much more active photographer I made my own frames and matte boards for my work. I still have all the tools and sometimes get to do consignment work doing this. Let me say anyone want to pay me 2 grand to make them a frame bring it on. Cost me at the most $100.00 for a fancy gold frame with UV plex, leaving me plenty left over to ship it.
All this aside, remember the frame is there to augment the image. When you spend lots to have it frame remember this. The image is the important part not the frame. I work my 9 to 5 in a image display company, right now I am mounting images in between typing this and watching for the boss
So the base line is never spend that much to frame something unless it is worth 10 times the value of what you are about to frame, 2 grand your image better be worth 20 grand. Or something really special. Before going to any frame shop, check out any local graphic places or even local photographers they can do it for much cheaper, or just look me up,
