"Is jpg the only file format supported by match and photon? I want to load RAW."
Match7 supports PNG and JPG.
Photon31 supports PNG, JPG and TIFF.
RAW is not supported by our tools at this point because RAW requires a separate, distinct processing step. RAW images contain extra image manipulation data so you can losslessly adjust white balance and exposure and interpret the RAW image data with a variety of different color profiles. The workflow we suggest is to use Photon more like a plugin that generates LUTs that you use in your RAW editor of choice.
"I don't know how to use CineTech Picture Styles and Vision Tech Picture Styles properly."
CineLook Picture Style
Use this picture style when you don't want to do any color grading in post. It creates a teal/orange color grade directly in your camera. You can shift the color palette and fine tune the look by adjusting the white balance. You'll get the best results when shooting at a slightly cooler temperature to accentuate the blue colors while preserving skin tones. CineLook doesn't usually require ANY color grading in post.
CineTech Picture Style
CineTech is a low-contrast and low-saturation version of CineLook. It is based on the same color transform profile and has been optimized for cases where you want to do SOME color grading in post. The color grade it produces is just as stylized as CineLook but you can dial in your own contast and saturation to taste in post production.
When to use CineLook vs CineTech?
Use CineLook when you want to create the final image directly in camera and don't do any color correction in post. Use CineTech when you want to get 80% of your final look in-camera but still want some control over contrast and saturation in post.
VisionColor Picture Style
This picture style is entirely optimized for color grading in post production. Because its color transform profile can work with the in-camera RAW signal, it is able to losslessly re-map certain color ranges before the image is compressed by the camera. The profile creates a neutral image that contains maximum color information in all channels after JPG and h264 compression.
VisionTech Picture Style
VisionTech uses the exact same color transform profile as VisionColor but has a slightly different gamma response curve and a raised black point. The VisionColor gamma curve goes from black [0,0,0] to white [255,255,255] whereas VisionTech clips black at [6,6,6]. We do this to optimize low-light color saturation in the compressed image signal.
When to use VisionColor vs VisionTech
Use either picture style when you want to color grade your footage in post (with LUTs for example). Shoot VisionColor when you have a lot of light available (daylight, bright studio etc). Shoot VisionTech in low-light situations to get the most color information from the shadows.
