10 - Blend Images with Feathering - Learn the Free Transform Tool, Opacity and Feathering in PhotoShop
Step #1: Open a New Blank Document in Photoshop ~
If you are making a banner, most are about 800 x 200 pixels.
If you are making a regular collage, try 800 x 600 pixels or whatever size you need.
Set the Resolution to 72
Step #2: Zoom Tool ~
Zoom Out by hitting Ctrl - (minus) or use the Zoom Tool
Or use the Zoom Tool
Step #3: Open a Bunch More Pictures ~
Open pictures of yourself or any other images that show you and your life positively.
Gather your images together & open them all in PhotoShop.
OK, maybe you don't have to have them ALL right now, but get at least 2 or 3 for starters.
Step #4: Combine them Together ~
Using the Move Tool 
drag all the images onto the main document.
Each image creates its own layer.
.
Once you have all your files imported, save the PhotoShop file as "your_name.psd"
Step #5: Turn Off the Visibility ~
Turn "off" the visibility on all the layers except two.
Click on the "Eye" 
to make the layers disappear.
Step #6: Make the Layers Fit the Main Document
Hit (Ctrl+T) or go to: Edit > Free Transform
Using the handles on the corners, you can adjust the size, tilt the picture, pivot it, resize it - whatever way you want.
Hold the Shift key down while you drag the corners, it changes all sides of the picture at once.
Adjust your images to fit your document.
Step #7: Lower the Opacity ~
Then lower the Opacity to a level where you can see both images, one over another.
Opacity helps you see where your images fit in relation to each other.
Step #8: Lasso Tool
Use the Lasso Tool 
to draw around the area you want removed.
A rough outline for now...
You can always undo by hitting Ctrl+Z
Step #9: Feathering
Go to: Select > Modify > Feather and set the Feather Radius.
If you're not sure what the Feather Radius should be, just try it!
Step #10: Select Inverse
Then hit Ctrl+Shift+i or go to Select > Inverse
Then hit "Delete." The feathered area should disappear leaving a smooth transition between the two images.
Step #11: Eraser ~
Raise the Opacity back to 100%.
Select the Eraser Tool (or just hit the letter E) 
Click on Brush in the Menu Bar.
Select a soft-fuzzy brush.
Erase the areas feathering didn't get...
Repeat the process on all your layers.
Step #12: Save & Attach your Work
Save your work as a .psd document to save your layers.
Only use .jpg if you are putting your work on the web.
Attach your file and try this if you dare...
