Are both your monitor and printer calibrated would be my first question...


Yes.

I have this same problem with Cardinals, sometimes. Have you tried changing the color temperature? I've found that if I cool it down a bit, the reds look a little truer. Hope you find a solution.

Thanks, Patty. I usually do, but actually on these I did not. I'll go back and play with that just a bit. One curious thing, however. When I took the sat down on the second one, it blued the red a bit and that was NOT what I wanted.

Yellow, reds...same problems. Sometimes I think it’s nature’s/God’s way (your choice) of saying: “Try all you want. There are some things I’m keepin’ for myself.”


Good point! Love it.

Kathy - can you selectively change the saturation and or vibrance using a brush so as to only effect the red colors?

In LR I did take the sat down in the red channel. There isn't a vibrance on only the red - sat, luminosity and tint. I should have looked at the tint and did not.

I've never heard of RawDigger. LR didn't find the red as blown, and its histogram does separate the channels. I usually underexpose red flowers by 1/2. Perhaps that's not enough.

Lightroom is showing you the JPEG histogram after conversion from raw. Anyone who shoots raw can benefit from RawDigger. It’s the best $20 you will ever spend.

72% of the exposure is based on the green channel so under exposing only 1/2 stop in this case may not be enough.

Is that true if I'm working on a RAW image?

Yes. I know of no other program that actually shows the raw histograms so that you can really see what is happening.

When I struggle with color and tint is the time I break out my color chart and photograph it next to the flower in the same light. Correcting that is easier and it will bring in the flower with it. I usually use the smaller version of the Color Checker which came with my Sekonic meter. Best of luck.

I learned about this tool in lightroom a few weeks ago, and it really does help images like this. It is the Calibration panel, and here is a great explanation of how to use it.

I agree. Reds are difficult especially in print they don't show accurately. My cousin was the chief photographer at Pacific Digital in SF. They did mainly high-end catalog and magazine ad work in a no-expenses-spared studio shooting with a large-format, digital Hassleblad. Since their clients mainly sold clothes and make up, he spent a lot of time on expensive LaCie monitors calibrated weekly to get the colors just right. The main challenge was getting the reds to print correctly; often the desired color was not as it appeared on the monitor.

I know it's there. Frankly, I've never seen it used or played with it. Interesting!

And I want it to be as I SAW it. Usually my monitor does that very well. And if there's not a large blob of red, the reds will print beautifully. It's almost like the printer gets OD'd on red when there's a huge patch of it in the image.

Only one issue...
It appears the calibration used in the video is not available in LR CC (Or I did not find it). I was looking at this setting the other day for other reasons.
