Photoshop Levels white point color picker alternative


Recommended Posts

Although there are alternative methods that can be reasonably quick depending on what you're doing, in order to replicate what Photoshop does with white point, grey point and black point pickers in Curves and Levels, it is a slow manual process in Affinity Photo.

Those pickers are something that anyone who uses Photoshop will absolutely miss in Affinity Photo as they save a lot of time.  Even more so with old faded scanned images – the Photoshop pickers are pretty great, along with the "Auto" button in Curves, that users can [ALT/OPT + Click] to bring up the settings.

To try to mimick the Photoshop white point picker directly, you need to determine what point of the image should be pure white (R=255, G=255, B=255) and manually adjust the white point of each RGB channel with a Curves adjustment layer – using the Info pane as a guide.  But it will quickly become a PITA, unless you only have a couple of images to work on.  Maybe Serif will add them in the future…

For the future, I'd invest in a light box, it will make editing a lot simpler, Just glue some fishing wire to the ceiling of the light box and hang the jewellery from that, you'll end up with decent exposure and white balance and no shadows to deal with.
