  1. Hi all, I was wondering how one would go about exposing or even using color effect filters like color gradients, Coral, Antique Suede or Day for Night optical filters while shooting on a digital camera and delivering in color. For example, say that you are using an Antique Suede. Wouldn't depriving the sensor of blue light be very destructive to the raw image? To my understanding the blue channel displays the most noticeable noise the most often. If so, how would you combat this? What are the advantages of doing such an important color decision in camera rather than in post apart from the "stops people from messing with your image" argument? Are there any clear optical or overall quality differences? Thanks in advance!
  2. Hi everybody, I'm reading about color sampling and I'm getting a lil confused about the difference between RGB and YCbCr. From what I've understood they are both color spaces, but YCbCr comes handy because full bandwidth RGB signals have a lot of color redundancy and they are not economically efficient for storage and transmission. One of the things I do not undestand is when in cameras happens the passage from RGB to YCbCr. For example, if I'm shooting with a high end level camera like Alexa or Epic what is the color space? And if I have a chence to choose between the two which one should I choose? And another thing, I've seen that in high end level monitors there is a hdsdi input but also different inputs for YCbCr signals, whit differents connectors for the different color components. why is that? Thanks so much in advance for the help, Davide
  3. Anyone can look into their film scanner and tell me what light source they are using? Seems like the Spirit Datacines and the Kinettas use either a short-ark Xenon lamp or an RGB tri-LED. But who manufactures these lamps? What are their models? Please help!
