    Hi, Is there any way to use two difference images Diff1 and Diff2 as (Diff1 = Tim2-Time1) and Diff2 = (Time3-Time2) to find changes between Time1 Time2 and Time3 in one change image. Thanks

    1) Diff3 = Diff1-Diff2 2) False color: R:Diff1, G:Diff1, B:Diff2. Diff1 change is yellow, Diff2 change is blue, change in both is white. Hope it helps, Jim

    Thanks Jim for you reply. I have slight confusion....as you said Diff3 = Diff1-Diff2 it means ((Time2-Time1) - (Time3-Time2)) = 2 * Time2 - Time1 - Time3. and then display R: Diff1 G:Diff1 B:Diff2 then I think we are not using Diff3 as generated earlier. Could you please elaborate how this is going to show change between Time1, Time2 and Time3 in single image. regards, Pk
