So, somebody please show me the benefits.
nope
Point out some details that you think are better and tell why you think they are better. Hue? Saturation? Smooth gradients? Dynamic range? What do you find superior in BasicColor?
BasicColor Input 5 makes matrix DCP profiles from your target (was it passport ?)... with ProfileToneCurve for "art repro" type as they call it (
to compensate the hidden deeds of ACR/LR inside the code... however they do not supply the recipe for ACR/LR UI parameters - like Process 2010/2012, etc and they shall I believe list that) or pure matrix for "non repro"...
it makes DCP profiles with color transform stored in CM* tags, not CM* (for WB related calculations) + FM* (for actual transform), it does not allow you to use a precise baseline exposure compensation value (unless you mod profile manually) and you can't (unless again you do it manually with other tools) change/inject the ProfileToneCurve...
nobody seriously pointed the advantage to use it (we can't count fancy UI as an advantage - but granted grid placement looks quite slick UI wise when I tested with my raws, I usually illuminate target orthog. to the target and then camera is @ 45 degrees to the target... so how grid can placement can work matters - I wish rawdigger can handle such angles better )
I think Iliah simply likes BasiCColor for its Discus wundermeter and some other, really useful, software that they make...
PS: and 500 Eu ? for that amount they actually shall include the physical DCam+ target and lifetime license to the Input.
