Need advice: How do you handle ambient lighting and color temperature in a retouching office?

Hi everyone,

I'm a commercial photo retoucher based in Seoul, Korea. I recently left a photo studio to set up my own private office, and I've run into an issue. I'm reaching out to the experts here for some advice!

I've heard that the ceiling lighting in an office significantly affects retouching work, but I'm not exactly sure how to gather information and set it up properly. (Back when I worked at the studio, the ceiling lights were calibrated to daylight, so I could accurately match the colors of the digital image by looking at the physical products.)

Currently, I don't know the exact color temperature (Kelvin) of my new office's ceiling lights. When I do color matching, the physical product and the digital image look slightly off, which is making me second-guess my accuracy while working.

I'm trying to decide between two options and would love your input on which is better:

• 1: Bring in a separate, Kelvin-adjustable light just for my desk/workspace.
• 2: Replace all the ceiling lights in the office to match a specific color temperature from the get-go.

How do other retouching studios maintain their lighting environment? I'm really curious and would love to hear how you all manage this!

Thanks for reading this long post! Looking forward to hearing your thoughts.
