Big_Stan Posted January 6, 2017 Author Share Posted January 6, 2017 I created a written set of instructions from the video. The goal is to change these from Photoshop speak to Affinity Photo speak. Landscape Astrophotography Noise Reduction with Image Stacking in Photoshop: https://www.youtube.com/watch?v=Rydg7JGTAbw Process images in Lightroom and then export layers to Photoshop EDIT (right click) > Open as layers in Photoshop Duplicate Stack > (Select all layers and drag to New Layer Button on bottom of the layer palette (see black square with lower left corner bent up) Now there is the original set PLUS a duplicate set Right Click & choose Convert to a Smart Object. Rename as “foreground” > hide (click on eye icon to hide) Hide all the sky layers EXCEPT one > Click the one visible layer and Click Add Layer Mask (see square w/ black circle) Click on add layer mask (white) > Select Paint Brush tool (BLACK large soft brush) > roughly paint out foreground on image Copy Mask to all remaining layers, CMD + Click on Layer Mask, and Click on Add Layer Mask button (see square with black circle on bottom of the palette) to paste layer mask on to next image in the stack Repeat for all sky layers, one layer at a time Shift click to select all layers > Edit > Auto-align layers > Auto Select Delete Layer Mask to delete mask for each foreground layer Select All the layers, Right Click all the layers and choose Convert to Smart Object (name it Sky), Layer > Smart Object > Stack Mode > Median Unhide foreground Smart Object and Layer > Smart Object > Stack Mode > Median To make final composite (merge foreground & sky layer), Select Foreground layer > Click Add Layer Mask Button > Use large BLACK soft paint brush to paint out sky > Click Option to clean-up mask Use small WHITE brush to clean-up layer.
