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
1000/0.2/0.0 or
1000/0.2/12.0 or
1000/2.5/12.0
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
1000/2.5/0.0
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:
120/0.8/1.0
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.
