This instructible will teach you how to make a realistic looking flag, but not only can this effect be used for flags It can be used for almost anything
Step 1: First Things First!
get your self a picture of some fabric and a picture fo a flag, you can use mine if you like.
Step 2: Put Both Images Into Photoshop
Open your fabric and your flag image and then apply gaussian blur to your fabric picture
(Filter > Blur > Gaussian Blur) and experiment with the radius to hide the detail of the fabric, keeping only the folds.
Step 3: SAVE!
Save your image as a PSD file (File > Save as). I saved mine as fabric.psd
make sure you save as a PSD or the next few steps wont work out.
Step 4: Next Up: the Flag Image
Start working on your flag image. Apply the displacement map filter to your flag with your fabric photo, mine is the fabric.psd file. (Filter > Distort > Displace)
use the same settings as i have done in the picture.
Step 5: Take a Look So Far
this is what i have got, maybe have a rest have a cuppa' and a biccy
Step 6: Adding the Wavyness
Go back to your fabric picture and select the whole thing with your marquee tool or simply by using ctrl+a, copy (ctrl+c), paste it (ctrl+v) onto your flag picture and change the layer mode to "Hard Light".
Step 7: Your Finished!
take a look at your artwork.. remember this effect can be used with allmost any picture try doing one of a friends face or make a wavy house!
