![]() And the third, in position three as the topmost layer has an opacity of 100/3 = 33. The second layer, above it, is in position two, so the opacity is 100/2 = 50. That is, the background layer (at the very bottom) is in position one, so its opacity is 100/1 = 100. For three layers the numbers (bottom up) are 100%, 50%, 33% like in the screenshot at left – and the very easy general formula to use is It’s not that obvious what percentage to assign to them. The fastest way (because we’re always in hurry and/or we may just want to give the blend a quick try) is to set each layer opacity. And you need to have an Extended version of PS. are a pain of slowness and add unnecessary complication for this task). This is doubtless a neat way, yet you may find this workflow a bit tedious (S.O. One method is to select them all, create a Smart Object containing the three layers, then (if you have Photoshop Extended), select in the menu Layer > Smart Objects > Stack Mode > Mean. three layers) and you want to give the same weight to everyone. Let’s say you’ve three versions to blend (i.e. You’d be tempted to set the background to 100% and the two above to 33% (or 50% perhaps?) – but you’d be wrong! It’s a bit different if you’d like to blend three layers 33-33-33. The 50-50 blend of two layers is a piece of cake: you set the bottom to 100% opacity and the top to 50%. This doesn’t necessarily involve that it must be the same person the one in charge, as my dear friend Marco Olivotto stated in a beautiful manifesto on collaborative color correction called Three Heads are Better than One.Īlthough masks and blending modes may be required, the easiest blends of all (33-33-33 or maybe 25-25-25-25) can be difficult to obtain, unless you know the trick! In Color Correction it is a wise strategy to produce multiple versions of a single image (that is: to correct the same picture few times collecting different variations), then blend them together in a number of ways – to get the better of each one. Three versions of a single image stitched together.
