I have one problem about DL.2 collage.I use two DL.2 units to collage,I programme "enhance collage" and use the grid to have the alignment to make sure it's not fuzzy,I also use the "fade left and right" for blending.If the clips are in low colour temperture or kind of abstract stuff,the image is seamless;if the clips are in high colour temperture and some specific stuff,the overlapping area is visible,and the overlapping area is yellow.
I think the lamps' not same luminous though they both are new.
Do you guys have suggestion for the problem?

    Vincent,

    If the lamps are largly different in hours it will cause problems with the blending areas. When using DL.2s in collage is it always best to have lamps with similar number of hours.

    There are a few limitations with the blending that can cause the blend area to be visible. These are especially noticeable on content that is black and white or brown. We have a few "alternate" blend curves that can be dialed in that can help with your problem. Try setting modifier 3 on the collage effect to either 144 or 145 and see if either of these help.

    Thanks,

    Yes,Matt
    The lamps hours are similar,they are range in 150 to 155 hours.And I try to swap new lamps for the DL.2,it doesn't help.
    What I would do is to select effect to be "collage" instead of "enhance collage",the overlapping area seems to be brighter,I use "fade left and right" for blending,it does help,the area is still visible but better.Contrast and black level option also helps.
    Refers to you suggestion for the curve,set it to be 144 or 155,so what is the corresponding value by percentage in cmy?
    Thanks

    Vincent,

    The corresponding value is about 57% on yellow. However, I would highly recommend using effect 2 for your collage settings because the values for the modifiers actually show up in DMX values instead of percentage values.

    This might be part of your problem as this will cause more pixels to be removed between the segments of your collage. Therby showing the pre-blended areas.....no need to use the edge fade shutters with collage unless you are going for a specific effect.

    Hope this helps. :)
