The Jigsaw Editing Method

Here's a simple and structured way of first dividing up the image into a closely-fitting 'jigsaw' and then separately and easily applying adjustments to each area.
Extra tip: You can create overlapping selections, then use 'Intersect' or 'Subtract' to create proper jigsaw pieces so each pixel is covered only by one final selection.

Masterful, deconstructed and then reconstructed.

[@DoctorZebedee]

Thanks Dave. Once again I learned something new

[@willwillis5186]

Powerful and effective way to edit. Thanks for sharing.

[@michaels7889]

Very useful method. It hadn't occurred to me to do it this way.

[@stephenhunt7655]

Thank you for sharing this technique 👍

[@yvesmolina]

Nice Tutorial, Thank you 👍👍

[@alangauld6079]

Interesting approach. I really need to get to grips with the channels stuff.

[@TheGREATdEEPs]

Thanks

[@BernieClark2]

Thanks Dave…… I’ve been looking for something like this….. a great technique to make sure all the selection ‘components’ fit together perfectly… thanks.

Thank you, Dave! Brilliant!

This approach using stored selections could come in quite handy if you are coloring in various segments of an old B&W photo. Something I have indulged in now and again. (Just a reminder - a selection can be turned into a mask by just hitting the mask icon with the selection active. The other way round - sitting on a mask CTRL-LEFT-MOUSE-BTN creates a corresponding selection.)

Smart

Great vid as always. Question, where would I use this vs the HSL adjustments you illustrated previously.

[@inaffinityforaffinityphoto3220]

HSL works when you have blocks of colour that it is able to separate, especially when these are quite complex and difficult to select by other means. The Jigsaw method is better when you have multiple areas that you can select. There are many means of selection (including using my free macros), so I'd first think about Jigsaw, then if selection is still too tricky, look at HSL. This is usually a very quick assessment.

[@ianwatson3393]

Very neat. But I wonder if it is not just as easy and effective to make an ordinary new layer from each successive selection and then have targeted adjustments to those as child layers. I have been doing that and it seems to work quite well for me.

[@inaffinityforaffinityphoto3220]

Yes, you can certainly do it this way, Ian. A value of a stored selection and masking is that the file size will be much less as adjustments take little space as compared to pixel layers. After tricky selection, it also can make editing much easier.

[@simonpayne7994]

The most common case is segmenting off the sky to handle it separately. Then you are probably better off with an additional layer and an appropriate mask. Using various grays on the mask instead of full white or black you can dodge and burn at will. A gradient on the mask can also be useful.
On the other hand, I was always afraid to even open up the channel menus. They are all too awsome und look so unintelligible.
Never open up menus you don't really understand or prod open a carboard box with lots of air-holes punched into it. Something might jump right out and bite you!
Thanks to this tutorial I feel at least a little bit more courageous now.
