In diglloyd: Sony A7R: ?Orange Peel? Texture Lloyd Chambers speculates about the nature of the “orange peel” texture of some of his Sony A7R images. Well, I thought it may be educational to take a single picture of tangerines, process the Sony raw file with Capture One Pro (C1), and show 2 resulting images, one without and one with “orange peel” texture.
I only modified the 3 Sharpening parameters Amount, Radius, and Threshold.
Setting these 3 parameters to minimum or maximum values like these
results in an image like the following without the dreaded “orange peel” texture.
The 3 different images are basically indistinguishable.
However with this set of parameters
the generated image shows the so called “orange peel” texture.
My take away from this is to keep the Radius smaller than 1, and Threshold larger than 0.
A good starting set for sharpening parameters in C1 that doesn't generate the “orange peel” texture might be something like this:
less than 300/0.6/1.0
or C1's default settings of:
I tend to look at an image at 200% to 400% magnification and aggressively move the sliders.
Then it's easy to spot the onset of “orange peel” texture and back off the sliders.
I shot the raw file of the tangerines with A7r2 and 55/1.8 FE.
