Last week, I started a technical series of how to post process photos of stained glass windows. In Part 1, I went over taking and selecting which photo to use, making adjustments in Adobe Lightroom, and moving the picture to Adobe Photoshop for more complex work.
Part 2 showed how to correct for distortion (i.e., keystone effect) and adding in a hue / saturation layer.
Now that a hue / saturation layer is in place, it’s time to create a mask. The mask blocks out what part of the picture I don’t want adjusted with the next step. In this case, I will block out the background, then invert the mask (i.e., turn it inside out) so that any changes I make will adjust the background only and leave the stained glass alone.
On the hue / saturation layer, click the white box (see where the down arrow is pointing). Another box will open up to the left, which I’ve put a big circle around.
To the far left are two boxes that should be black and white. When I hover the mouse over them, they are called the foreground and background color. Make sure the black is on top as shown here. If it isn’t, click the tiny double arrow (shown with the tiny circle around it) to reverse the boxes. If the black box isn’t on top, this won’t work right. If my boxes have different colors in them, I click the itty bitty boxes next to the tiny double arrow. That will restore the default colors of black and white. I will have to click the double arrow to put the black box back on top.
Yes, itty bitty is a technical term, although I don’t think Adobe has it copyrighted :)
Now it’s time to brush in a mask and cover up the background.
In my last post, I began a technical series of how I processed some photos that I took of stained glass. Click here for Part 1, which explains how I selected the photo and began processing in Adobe Lightroom. Click here to see the original post with all the photos.
At the end of the last post, I finished my initial edits in Lightroom and loaded the picture into Adobe Photoshop for further editing. This begins with what I did next in Photoshop to improve the picture.
The first thing I do is create a duplicate layer. This way, if something goes wrong, the layer can be deleted, a new one created, and I can start all over again. In other words, I haven’t altered the original photo. If I make a mistake and forget to add the layer, I save it right away with a new name so that I don’t accidentally overlay my original photo. If something goes wrong, I have to delete the entire photo, but it’s better than having ruined the original photo.
To duplicate the layer, right click on the layer, which is shown in the down arrow and mostly hidden under the pop-up box. On the pop-up box, click duplicate layer. When the next box comes up, you can name the new layer or not. You can always change the name later by double clicking on the name of the layer and then editing it.
