For color grading purposes, anyone knows how to deal with Log footage? Let's say I'm working with c-log 4444 2K alexa prores... would I need a LUT to convert log to linear? Can I grade the log footage... and then, when do I would apply the 709 curve to be ready to broadcast? and what if I wanted...

Hi, I recently asked a question about the amount of light you need to have proper exposure using non-processed signal such as RAW and in a different way, S-log or C-log material. The point is that manufacturers are giving some ideal IRE settings for what they believe their curves apply. For...

Thanks a lot Dave, What would you think it would be the lowest level in which you'd place a face, let's say you're in an interior and you want to keep the ambient dimmed... if 40IRE is medium grey, placing faces at this level would be underexposing the skin tone for about 1 stop... I've noticed...

Hi Dave, I recently shot a documentary short film in Bolivia using a viper camera and 422 raw mode. We didn't have any budget for lights and we were really short on our crew... so we almost always shot using available light. I tend to prefer backlit situations for the scene and we tried to use...

Thankyou Dave, What about REC709 conversion, when you have to lift the white levels to their proper point, isn't it like pushing the gamma curve? What would be the difference anyways? Is the bigger bit depth the key point in that conversion? And what about the skin tones, actually, the dp is...

Hi, I'm working as a HD Technitian in a HD feature film in wich we're using a couple of viper filmstream cameras. As they feed a sort of Log curve the image is flat and greenish. We've been correcting the monitoring image by applying LUTs and would like to hear some opinions about exposure...

Hi, this might be a little overexplained but I am a little bit confused about exposure in digital media where Log curves o raw formats are used. In fact I would say that my question would also be applied to analog cinematography in the way the latitud is increased regarding the output media...

log curve log curve Thanks for the answer mr Mullen, about the log curve, what I've recently read is that they make an interpretation of the data obtained after the a/d conversion has taken place in which they try to adapt the output values to the human perception of changing values of...

Hi, I'm working as a hd technician but has never understood how is measured the noise in a digital camera. I also see that this noise is very much likely to be noticeable in the dark areas of the image, this shouldn't be a problem if you intent to lower the blacks, but what about the dark...

Hi, I'm preparing a feature film that's going to be shot with two vipers and recorded onto a OB1 (444 RGB 10 bit log) to be transfered into a 422 rgb signal (captured via downconverter). Would like to know if anyone knows the basic workflow (including transfer codecs, if to apply a correction...

This week, while I was making an interview with a couple of reds I took a look to the set that a big Tv channel was putting on for another interview. The interview took place in a big room where some outdoor light was coming in trhough the window, and the cameraman used a bunch of kino and some...

Thanks a lot mr mullen, your answer is so complete that I've printed it to be able to remember and study all the data you gave to me!

I've just shot a low budget movie on the hvx200 and we're about to finish the editing process. So I've began to think about the nest step and, even if we just don't know how will the outside world react to our self-produced experiment, the directors want to have a realese print to project it on...

Anyone knows how to backup the footage shot into a fs100 hard drive with the panasonic p2 into a tape, using the camera as a video?

I'm not sure of having understanf your question, you can have stocks either balanced to tungten light or to daylight, both of them with their own sensitivity. Sometimes you have a reel that specifies the ISO for tungsten and a different number if you're using daylight, that's because they're...

I'm about to shoot a movie (low budget of course) with the hvx-200, I've tested it's quality and I found it superbe, but by reading it's description there's something I don't understand. The ccd is supposed to have a natural resolution of 720 lines on progressive scan mode, or 1080 on...

I´ve just shot a commertial that took place outdoors in what was supposed to be a garden at early in the morning. As the main character arrived at 15pm (first nightmare) and we had to shoot 4 different situations we were in a big hurry... as usual the sun did set down before we finished and as I...

Thinking about the progressive mode of the new dv or hdv cameras I would like to know your opinion about wether to shoot on progressive or on interlaced. I've talked to an editor who prefered the interlaced pictures so he would be able to give the picture the specific cine-look he wants. That's...
