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.
