Projector Central has posted a very interesting article on tests of home made screens vs commercial screens, with actual side by side photos. Well worth a read:

Interesting, but I can't make out a difference between the test shots other than for the contrast and black levels... sheesh, and it takes a $1,000 screen for that small of an improvement? Good thing my trusty Da-Lite cost me less than $200. [Wink]

Which isn't much more than the DIY screen, plus you don't have to do a thing but hang it up. [Big Grin]

Cant really see the difference in the screen shots.

To spend $1000.00 plus you would want to see more for your cash.

Ive been to some old drive ins in my youth that were no mote than paint and wood. Keep it bright keep it loud nobody spot the difference !!

Hi Paul
Paul you picked an interesting topic the site was very interesting the use of what you call velveteen in the frame is a good idea. The screen I made was constructed from two sheets of custom wood 12ft by 4ft one sheet secured to the blockwork and painted with vivid white matt finish "water based" I used a roller. The second sheet was cut for top and bottom masking covered in black fabric and butted to the first sheet.The side masking I used an old curtain track and using 8inch wide hardboard inserts into more of the black fabric I could slide the L and R sides to complete the side masking. The screen is basic in nature and cheap to make. I find that by enlarging the projected image just slightly into the masking I get a defined edge to the picture, I feel it improves the image overhall, one important point if possible keep the screen away from white walls and ceilings as the reflected light will defuse the projected image. The screen works well for both video and film, some people are more imaginative and have included motorised masking etc. It would be interesting to read what thoughts others have on the subject.
