It wouldn't be summer without salvia.
Bright red in full sun has often been problematic for me in photos, and I sometimes see the same issues for others. For some reason, bright highly saturated reds want to over-expose in a digital image. It is as if the camera's light meter doesn't react to red light in the same way that it does to green and blue. Sometimes I deliberately under-expose bright red maybe as much as 1 full stop, and that can help. In this case I did some manipulation in Lightroom during RAW conversion. The LR app has a nifty feature called "Recovery" that brings back the detail and texture (darkens) just the very brightest areas in the image without darkening the mid and low-light areas, like the Brightness, Exposure or Contrast controls will. Maybe PS has this too (and I'm sure you could do this by fooling with the gamma curve), but in LR it is a simple slider and I find it very handy. In addition to this control, LR also has an 8-position color channel brightness control that I sometimes use too. With this I can darken the red and maybe brighten the green at the same time rather than do an across-the-board change. Again, this seems to be a much easier and more precise control than anything I have found in PS so far. Canon 1DMkIII Canon 16-35mm f2.8L lens @ 22mm; ISO-100; f8; 1/100-sec JD |

You can adjust the brightness at any level you choose without affecting the brightness of other levels. And you can do it selectively to the R, G, B, or RGB Channels. It gives a lot more control than LEVELS, which affects the entire image. Bob Williams |
