[Additional Graphs]

Wow - I completely missed that...

 

Agree that the skin tone line would be a nice addition to the vectorscope whenever someone can get around to it... but the RGB Parade is the big one I wanted for use in Affinity - and there it is!

 

Also, can the scopes be resized?  It seems to be a fixed-size square no matter how wide I make the palettes.  If not, I guess that should be on the request list :-)

 

 

Thank you!

[Additional Graphs]

Currently, Affinity Photo provides only a histogram graph for analyzing the image - this is in line with most photo software, but there are much more useful graphs which are commonly found in color grading software used in video work, which are no less useful when examining photos - and all of them are more helpful than the histogram.  These include the waveform diagram, vectorscope, and RGB Parade.  It would be nice to have these available as options in addition to just the histogram (though I will admit I'm not quite sure as to whether a CMYK Parade would be graphed right-side-up or upside-down due to the subtractive nature of the color system...)

[Color Channel Mixer]

I would like to see a channel mixer offered as a filter / FX layer in Affinity Photo, similar to the one in Photoshop or Resolve, except extended to support the alpha channel in the same manner as the others.

 

For the benefit of those not familiar with it, I've attached a screenshot of the "RGB Mixer" in Resolve.  The idea is that for each color channel, you can provide a mix of the color channels in order to make that one up: in this case, the output red channel is made up of the full input red channel, the output green channel of the full input green channel, etc.

 

I'd like to see a set of controls for each of the "output" channels, allowing a mix of all of the "input" channels.

 

This has numerous applications: custom grayscale mixes, fixing bad channel data by creating a mix of the others, a form of chroma keying (by mixing into the alpha channel), etc. - it would provide a number of capabilities in one blow, and I would think it should be relatively simple to implement.
