Capture one express lens correction question

[LDJS Photography]

Hi. In C1 express in the lens tab where you can make corrections there are 3 tabs I am unsure about

Distortion

Sharpness falloff

Light falloff

These are at default of zero. They go higher than 100 but I just figured 100 for each was the correct amount

Should I leave at default or am I correct that 100 means 100 percent correction?

Also is there a toggle button where you can see the effect turned on and off like there is in ACR and Photoshop? (For example in photoshop it looks like a little eye and you click it and it shows with and without the new adjustments for curves / levels etc)

Thanks

From my testing with various lenses, yes the 100 seems to be the correct value to use, weird that it defaults to 0 when choosing the profile.

about the eye button I don’t know, i am not really a power user.

I believe that 100 is the 'fully corrected' position.

I generally start with 100 for sharpness drop-off and distortion correction and 95 for Light Falloff.

I don't know of a before/after toggle for these three controls but if you click the anti-clockwise arrow in the top bar of the Lens Correction group ALL the Lens Correction adjustments will drop back to whatever your default settings are. If you then use the standard 'Undo' button combination on the keyboard the values will return to where they were before you clicked the anti-clockwise arrow. The 'Undo' button combination on a Mac is Command+Z. I don't know what it is on other operating systems.

Something I somehow only recently learnt (thanks to this forum), selecting 'manufacturer profile' rather than the profiles named after the lenses (which are simply C1's take on things and not actually very good), will correct the lens the same way as the jpegs in camera, because the corrections are based on the exif data within the shot provided by Fuji.

This means I'm no longer playing around with the sliders you ask about above in an attempt to replicate the jpeg correction.
