p.1 #1 · p.1 #1 · A simple way to Calibrate your DSLR in Lightroom | |
I decided I needed to calibrate my Canon 5D3's colors in Lightroom. So I purchased a nice, inexpensive color chart, and took a few exposures outside. I soon realised that it's very difficult to eye-calibrate a sun-illuminated color chart while comparing on-screen colors to a room-lit chart (even when that chart is lit by a Solux lamp).
It took a while, but I realised that if I'm looking at a screen, it would be a good first step to actually photograph the screen, and then compare it's colors to, well, it's colors. Here's what I did:
1. Create a color patch image. I wanted the fully saturated primaries (RGB) and the in-between colors. I also included darker patches of these colors. You can get these by keying one of [255 224 192 160 128 96 84 32 0] into your software's color selector. I used [0 40 83 126 169 212] for a variety of grays.
2. Photograph it in a dark room, while significantly unfocused (or the sharply-focused RGB screen pixels will cause problems).
3. Import the image to LR. Set the white balance and brightness.
4. Pick the *closest matching* Camera Calibration/Profile:. In my case, this was the Adobe Standard profile. (I spent many hours calibrating Canon Camera Faithful, Neutral and Standard. In the end, after step 6, the Adobe Standard profile and calibration was closest).
5. Adjust the Red, Green and Blue Primary Hue and Saturation. Note that when you adjust one saturation, the other colors are affected. I don't have tips for this, you just have to work through it. You will need to adjust in small increments, and iterate several times.
6. Adjust the 'HSL All' panel controls to fine-tune the colors.
While Adobe and your camera are calibrated for a pleasing appearance, you might want a more literal interpretation in some cases. I seem to prefer my landscapes with this literal calibration more than the presets.
