This is something that involves photoshop, so it could never be used for dpchallenges. However it is usefull for times when you're not too particular about heavy manipulation in a photograph. The first step is to get some good source lighting, I use a clamp on light from a hardware store with a floodlight bulb. The next step is getting a semi-transparent bag from a grocery store. You take a few shots of the bag against the light, with as many creases and wrinkles in it as possible. Try and get a lot of areas of light and dark. Next you take the image you want to manipulate, and open it in one window of photoshop. Take the image of the plastic bag and open it in another window. It's handy to keep the image of the plastic bag a few degrees larger than the image you're manipulating. Next you do a select all on the plastic bag image, then you paste it as a new layer onto the desired image. Then you change the blending mode to multiply, and move the plastic bag image around as needed, until you have the desired effect.
The downsides to this is mainly is that you can't control what the lighting looks like too well, and unless it's implemented in the proper settup (generally a really close shot) it will look fake. However I've had a few images greatly enhanced using this technique.
Another thing to note is that you can play around with coloration of the plastic bag image, making it different colors. Totally desaturated seems to work the best to me. |
