Adobe Photoshop has many serious uses, such as marketing, photo restoration and video special effects. But it can also be used for a good laugh. In fact, Photoshop is the ultimate gag tool, since you can do virtually anything with someones picture, from giving your favorite aunt a beard, putting devil horns on the boss or putting someone in a dress. This is quickly and easily accomplished in Photoshop.
Load the image you want to alter onto your computer, either by connecting a digital camera to your computer via the USB port or by scanning the image in. Then load an image of someone wearing a dress. You can get something like this online, or you can take a photograph of someone you know. But it helps if the person in the dress is about the same build and standing in roughly the same stance as the person in the other picture.
Open Photoshop. Select "File" and click "Open." In the dialog browse to the image that you want to add the dress to and open it. Now select "File" and click "Open." Browse to the image that has the dress that you want to use.
Click on the "Quick Mask" icon at the bottom of the toolbar. Now use the tool to paint over the area of the dress. Try not to select anything other than the dress. You can adjust the size settings of the tool as you work in order to get to small corners and detailed areas like fringes or lace. Once you have entirely covered the dress click on the "Quick Mask" icon again. There area you painter over has now been turned into a selection. Select "Edit" and click "Copy."
Go back the the other image. Select "Edit" and click "Paste." The dress is now in the image on its own layer. Now select "Edit," then "Transform" and use the "Scale" and "Rotate" functions (combined with the "Move" tool) to position the dress where you want it. If there are still bits of arms or other clothes peeking through the edges, select the background layer and then select the "Clone" tool. Hold down the "ALT" key and click on an area of background that is very near to the area peeking through. Then use the tool to paint over the area, and Photoshop will replace it.
