Red Eye Reduction
« on: December 18, 2015, 06:04:18 pm »

Found a photo with some visible red eye today. Is there a red eye reduction tool or technique in C1?
Thanks.

There is no red eye tool.
However you can paint a mask on the offending area, use the color picker tool to select the red, then adjust to taste.

Search the Phase One youtube channel, they have a video somewhere that explains how to do this. Probably V7, but the method hasn't changed since.

Hi,

'Red eye' can come in many variations. That's possibly why Capture One doesn't have an automatic tool for it, plus that Professional Photographers never have such issues ;) (if only ...).

It's not too hard to correct in C1, especially because you can use a Local Adjustment Layer. With that, you can make a selecting mask which includes the pupil part, but not the catchlight to the same degree.

Just zoom-in and mask in the Red parts (or other color retro-reflections in animal eyes), erase parts in the mask that you do not want included. Now desaturate (generic in the exposure tool tab or detailed based on color selection in the color editor tool), and darken (e.g. by dropping the exposure, or using a Luminosity curve, or with the Color Editor).

The really complicated ones are where the reflection of objects or people on the eye's surface, are mixed with retro-reflection by the retina. Since you usually want to keep the color of surface reflection, but remove the color of the retina reflection, you'll have to use specific color selections, for which the Color Editor is better suited than a generic desaturation.

Use your judgement, but avoid making the pupil uniform black, leave some dark grey in there and some shape to it with a gentle gradient. The mask with variable density will help in achieving a natural looking effect. C1V9 also allows to create a mask based on color selection, which can then be edited to only affect the 'Red eye'

Cheers,
Bart
