This Tech Help Guide will explain how to design and assemble blue and greenscreens and backdrops for photos and video, as well as how to easily and inexpensively build a portable frame to support these backdrops out of PVC pipe or metal conduit.
homemade greenscreen

Because I'm cheap...and don't have the money, anyway...I decided to try my hand at creating my own backdrops.

I bought a full size tan sheet (poly/cotton blend) and a large bottle of dark brown Rit dye.  

I folded my sheet in half and half again.

I held the sheet by the corner (so the sheet looked like a ghost).  

I then tied off every 4 inches with a shoe string (I opted not to use rubberbands, because I didn't want too much distinction between the two colors).

I filled a small cooler 3/4 full of cold water and 1 cup of sal, then added the dye.  I put in the sheet and soaked for 20-30 minutes.

I dumped the water (in the yard!) and rinsed the sheet with a water hose for about 10 minutes.  

Without untie-ing the sheet, I left it to dry outside for about an hour.  

I then wrapped the sheet in an old towel and dried in the dryer for two cycles.

Here are the results:
Brown Backdrop

  I thought I'd expand on my post from the front page about Backdrops. First you need a portrait, so heres an original..Original..as you can see it needs help. So first we start in Photoshop, and we adjust the levels and do a little playing with color...then I cropped it... Adjusted Portrait.
 Now we want to get rid of the background, so we can play with others looks. There are a lot of ways to get rid of the background, but heres the way I did it. 1)..opened the image up in the extract window...you'll find it in the filters. Once you trace the body of work you wish to keep,you then fill it with the bucket tool...then select OK. Now you should have something like ...This.
Now comes the part you can not duplicate using just one real backdrop...putting many different backdrops in behind the subject to see which one suits not only your eyes choice, but the color tone of their faces. You can see how hard that woud be using just one piece of cloth.
  So here are some examples of digital dackground choices...
 A.  Using the ice picture I took.
 B.  A grey layer I made in Photoshop.
 C.  Grean layer made in Photoshop.
 D.  A picture I took a Disney Land.

  So even thou I have 6-7 backdrops, one...a green chromeakey and another 2  of which I dyed and painted myself...you can see the advantages of digital backdrops..hope this was od use ..

 This is a shot of ice crystals.. on my car yesterday..just a small amount of tweeking with levels..and you have a photographers backdrop for a portrait...ice..from car ..heres an example of it with a hand...Why...why not!...Some people pay good money for background shots for digital work...and to think they can be found around the house...cool
