APh - Use of grey card.

[Marco Vazquez]

Hi all, happy new year.

 

In video bellow, I show you how to use of a grey card in order to set the correct white balance to your RAWs photos. I used datacolor SpiderCube for my test.

 

As you can see in the video, AF has some bugs on Develop Persona and Preset tool.

@Affinity team, please could you check the bugs on the video.

 

 

Regards.

Is there any sound on that vid ? I'd like to know what's going on

 

The whole grey card thing does remind me that I'd love for AP to recognise a colour passport and adjust white balance default accordingly.

Sorry harrym, no sound on video, I'll try to explain:

 

• 00:17 - Select White Balance Tool
• 00:20 - Click on grey 18% zone
• 00:24 to 00:44 - Set your adjustments, as you on can see White Balance section, ºk is 3403 and tint -8
• 00:45 - Show Clipped High Lights and Shadows
• 01:35 - Save Preset with name 'SpiderCube'
• 01:45 - Save by  second time Preset with same name, (I think this is a bug, AP doesn't show message that all ready exist)
• 01:59 - Save by  third time Preset with same name
• 02:10 - Load new image
• 0:2:26 - Apply preset previously saved with name 'SpiderCube', on this step, white balance are disable (second bug), you just need to enable, (third bug, temperature is 5867ºk not 3403 and tint -5
• 02:39 - Delete Presets, no need more, must delete all that you created. 
• 0:3:02 to 04:45 - Use of history tool, No tab or tool or Menu shows Presets saved.
• 04:46 to end - Develop

Just to clarify, just need to save one time the Preset, I saved three times to show a bug in AP.

Are you sure that the AP white balance picker here is calibrated for an 18% gray (mid gray) level and not instead a 90% reflective white point? - However, the develop persona would be better suited here, if it would offer to choose and select with the usual common three pickers (a white point, a gray point and a black point picker) for making adjustments. That's BTW also the reason your SpiderCube has all three of them on it!

 

Further I miss the same for the AP curves tool here, beeing able to quickly adjust the color temperatures of an image by pointing with a dedicated white, gray, black picker on an image and also being able to save/reload these individual setup curves adjustments for reuse.
