I want advice on what to do here: I've been providing framed prints of my landscape photography to the hospital where I am employed as a nurse. I have done about 36 so far over the past 3 years. All have been the same size: 24"X36" black and white prints on Hahnemühle Photo Rag® Ultra Smooth 305 g matte paper, 4-ply white cotton rag mats, 3½" wide on the top and sides, 5" on the bottom, acid free Foam Cor backing, 1½" flat face black frames, 1⅜" deep, .118" non-glare acrylic glazing, a dust cover and security hardware. I charge $526 plus $20 to hang them. A week ago, they asked for some proofs to choose 3 from. I provided them (50) 9"X12" prints on metallic paper (to better represent the affect of glazing) to choose from. They came back with a request for bulk pricing for 8 with the above dimensions. Since they have been good to me, I took off $100 and the $26 for each of the 8. They agreed and I asked for them to tell me which ones they want. Two days later, (today) they are now asking for a price for just the 8 prints and they want to buy all of the 9X12" proofs. I don't like that. I priced my work on pretty much the high end of what multiple framing sites would charge for everything but the print. I never calculated the print's worth, but it sounds like they want to get them framed cheaper somewhere else. And as far as the proofs go, I have no idea what they want those for. I think I want to refuse to sell them the big prints unframed and if they want the proofs, I want to frame those too.
Any advice on how to handle this without affecting my reputation?

The way I see something like this and this is my opinion only, Sony could have contacted him to promote their cameras or he is now using Sony because it fits better his photo style.
I am a Nikon user and I feel no need to switch to any other dSLR system. I have been using Olympus for several years now and it offers me small cameras and lenses that are easy to carry anywhere and they have excellent quality. No, I will not quit using Nikon.

I guess each one of us should get the gear that makes us comfortable with our shooting style.
