Hi,

I just received the famous blue gel filter, i order them in a specialize event shop. As a lot of you already avert me, it's not miraculous but i think the movie a more confortable to watch. i tried them on my more reddish movie and as you can see there is a bit of diference. To argue my point of view i choose dracula and once apon a time in the west because one have a lot of dark seen and the other very bight so we can see the effect on different contrast.

For the one who didn't notice the difference, the top image is the one with filter.

I'm please with the result but i'm wondering if some of you have better result and if so what filter do you use.

It's said that using a xenon lamp improves the pictures since the light is a little bit blue but I have never tried (I have no xenon projector).

A few years ago Hugh Scott Thompson proved a point to me, you do not need to spend small fortunes on lens filters because he sent me, and at no charge, four plastic gels, two blues, a light blue and a darker blue, also two yellow gels. Hugh said just try them all and if need be mix two together. Using the most basic of clip holders they work perfectly free standing in front of the projectors lens. My recent print of Death wish had red hue during the night scenes and the blue one completely cleared the red hue. While i said i dont keep faded or fading prints we do still have a small number of these and the gels works absolutely perfect.

Hugh also recently sent me some images of a home made top cover to block the flood of light coming out of the top of the Elmo 1200's made from, (i think), a beer can. I said i would put it up here but as yet i havnt so i will find it and get it on here.

Back to the gels, the light and med blue ones seem to do the trick perfectly. No need for expensive lens filters. [Wink]

Dominique, i don't know if we can see that on the photo but the filter tend to make the image darker maybe the xenon lamp can give better result on this point.

The blue gel is a good plan B to enjoy reddish movie if a have the chance i will try other brand to see if their is a difference. I have seen on some forum that the purple filter can work but after some test it's not good. If you want to buy filter, buy light blue and mix them according to the film quality.

Yes Tom, i have seen some DIY support for the gel but i will try to create one with the 3D print since it's very easy and cheap now, i hope i a create one who can be more esthetic and practical. If i can achieve that i will post the plan on the forum.

The glass Cyan filters are much better, as thwey let more light thru. harder to get ahold of, though.

I have experimented with plastic and gel filters for years, (taking one or more filters and combing them, ect ect0 and I have had very good results, except for, of course, the loss of light.

Actually, some forms of color fade (eastman) work really well with cyan/greenish filters.
