Adjustment Layer Exercise
One of the first exercises you will try your hand at in this class involves importing an image into photoshop, then editing it four times to see the effects of adjustment layers.
Take a selfie and email it to yourself from your phone. Download the photo from your email, then save it to your folder.
- Open the image in Photoshop (Control-O), then select Full screen Mode (F on your keyboard) to see the image w/o being distracted by the busy desktop.
- Crop out the rest of the photo with the crop too (C), choosing Enter to approve the crop after you have adjusted it. These pixels are now lost, but you may undo this by using the quick edit Control+Z or Edit-Undo from the top menu.
- Double click on the layer name to unlock the background, but name it “background” or “original”. Now re-save the image using Control + Shirt + S for Save-As. Call it E02LastFirst.psd (make sure this time you save it as a Photo Shop Document using the .psd extension!)
- On the top menu, choose Image – Image Size then type in 400, setting the pixels to a width of 400 pixels. Make sure the box labeled “Constrain Proportions” is checked, or you image will get badly distorted!
- Again on the top menu of the interface, select Image- Canvas Size, then choose a canvas size of 1600 pixels to allow for the 4 consecutive images that you will place side by side (see example at the top of this post).Be sure to anchor the pic by clicking on the left center box in the tic-tac-toe looking thingy near the bottom of the window .
- Leave the original photo as it was, except for a quick Levels Adjustment under the Layer Menu-New Adjustment Layer-Levels. You can also use Control+L. Your original will be your ‘litmus test’ to see how your new adjusted images compare.
- Select the move tool (V) from the tools palette, but this time hold down the Alt key as you select the original photo and watch as a copy of the image moves over to the right!
- Select the Magic Wand Tool and set the tolerance low (below 20 or so) so that you will easily select only the bright, green background, then use Control + X to Edit-remove the background from each copy of your original photo.
- Now that each of the 4 photos are placed side by side, go into the layers palette, – on each layer in turn and re-name them with names that will help you remember each one. Example: kyle green kyle purple, kyle red.
- In the layer menu, choose New Adjustment layer, then choose Hue/Saturation. Make sure you click in the box that asks to link this new adjustment layer to the photo layer you selected from step #10. In the window that is provided, adjust the color, saturation, and lightness until you have altered the original photo distinctly. Do this for each of the 3 new versions of your photo, so that all three are completely different from each other in Hue, Saturation, and Lightness.
Last but not least, see if you can import new backgrounds to use to fill the empty space left by the removal of the green screen.
