Still loving the M6II, even more with new DXO

Hi Larry, you referred to Deep Prime and Deep Prime XD "intensity" settings. I don't have that slider on my version. I have three sliders: Luminance, Dead Pixels, and Noise Model. Are you referring to the luminance setting? Is it called something different on different versions? I have an intensity setting on my unsharp mask panel. Out of interest, how much sharpness do you think unsharp mask adds to what Deep Prime already gives with its lens sharpness settings? I haven't yet used any unsharp mask on my Deep Prime and Deep Prime XD images, because I find that the lens correction modules, with their associated 'lens sharpness' setting, gives me plenty already.

Apologies, yes I did mean DeepPRIME 'Luminosity' and not 'Intensity' (that's a sharpness setting).

I tend to set the Lens correction Global setting to a standard value for a particular lens (zero for the EF-M 32mm f1.4, 20 for the 22mm f2 and 11-22, 50 for the EF-S 55-250 IS STM for example) and then fine tune using Unsharp mask setting. The reason for that is that the lens correction settings are a black box to me, I don't really know what they do, whereas the unsharp mask settings are more transparent and I'm very familiar with the settings and their effects on the image.

Particularly the 'Edge offset' (which I think is badly named) in the unsharp mask allows you to increase the edge and corner sharpness relative to the center sharpness... the DxO lens corrections don't seem to balance that out and some lenses like the 15-45, Laowa 9 really need it.

The other reason I use the unsharp mask settings is that I tend to use manual focus lenses fairly frequently (Roki 8, 12, 135, Laowa 9, EF-S 55-250 IS STM with the 1.5x teleconverter [no DxO corrections for the TC] and especially a Meade ETX-125 telescope for astro). The DxO lens corrections are disabled for lenses DxO doesn't know about, the only option is unsharp mask for those.
