Questions about the changes history

[Nadar]

Hello everyone

 

Can someone explain to me how does history of the changes work when one click on the little clock at the bottom right ?

One can indeed select a window or click on the camera at the very end.

What is the difference ?

Thanks

Hi Nadar

I recommend you watch the following video - https://affinity.serif.com/en-gb/tutorials/photo/ipad/video/286486578

The camera icon is for Snapshot work, such as when using the undo brush tool. I hope this helps!

Thank you very much Dan

I do not understand what you mean by "snapshot work" and the the "undo brush".

Can you explain it to me ? Thanks.

Snapshots are used with the undo brush to paint in early versions of the documents pixels, for example using the burn brush tool changes the images pixels, so if you select a snapshot (the camera icon) in the history panel and then use the undo brush, it will revert the pixels in the image to before the tool was used, without undoing all of the pixel change. I've created a quick screen recording showing this in action-
