Total beginner to Blender here, so please pardon my general ignorance.
I'm trying to render product shots of some photographic prints for my wife. I've bought an interior scene from evermotion which already had some prints on the wall, and am trying to substitute her photos for those prints.
To do this, I've deleted the meshes for the existing prints (they were using a texture atlas for all of the prints, which seemed like unnecessary additional complexity for now), added in planes for the new prints, and used a simple "image texture" material on them. This approximately works, but the photos look over exposed when I render -- this is the problem I'm trying to solve.
Moreover, I'm a bit confused about what's actually happening: she sent me JPEGs of developed RAW files which had already had exposure, tone-mapping, gamma, etc applied in Lightroom. My understanding of 3D graphics was that you generally wanted to work on linear data and then apply the tone-map and gamma to the final render. So I guess I'm not surprised that it's come out wrong, but I'm at a bit of a loss to understand the best path to making it "right".
Would appreciate any pointers on this! Thanks!
