I downloaded the trial and coming to grips with the GUI, only looked at how it handles a couple of images so not a review but initial observations.
1) The default rendering with DXO Standard was quite something, I looked at the fly on the leaf picture posted before and at 1:1 viewing I could count the hairs on the legs of the fly.......without double checking I don't recall that in the LR PP'ed image....plus the noise reduction looks well controlled.
1a) As I understand it ~ if altering the default settings as needed, it can be "saved as" a user named preset???
2) Re: default sharpening as above:- this surprised most of all especially as drilling down I realised the only sharpening being applied was 'Lens Sharpening' i.e. the body & lens profile based sharpening. (NB I found the USM in another panel and it was not "active"!) So in process terms the "Capture Sharpening" is very good
3) I did not examine, by switching on/off the various elements of the preset panel to see the effect of each
4) Minor niggle ~ though this is a workflow question(?). In LR when you use a slider to tweak the effect, if you want to reset it you double click the slider name
I surmise in DxO I will have use CTRL-Z to go back a step, AOK?
Summary:- my approach to processing has always been KISS principal so DxO does look like a worthy contender as a raw processor, costly even with the 25% discount but if my workflow and the end result "works" then might be a must have???
