Thanks for the explanation. It was really useful.

Thank you. This was really helpful.

Curves adjustment is really old school method. It's been around for a long time. I started photography in 2003 and curves S-curve was first lesson in Photoshop. Now I use Lightroom and NX Studio. Both have curves.

How can I reenter the curve edit dialogue once I've made adjustments and left it? The only way I found was clicking on "default" again what leads to a lose previous adjustments.

As editor, when do you know that are colors are almost same on reality? Remember need an aquire color image not as you like - this must be in real estate photos. Smartphone on 2 D images do a good job vs old DSLR
