  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Dynamic Range...

That is one that will work.

I know you've already said 300x, but the SanDisk Extreme IVs are rated at 266x and that was what was in the original photo posted of CF working with Redcode. Is 266x not fast enough anymore or over sustained write times or something?
 
Graeme are you seeing the wavelet compression act as a noise reduction process? It seems like part of the boost you're seeing would come from your codec effectively giving it a de-noise pass.

Dynamic Range is tricky to measure. And everyone seems to use a different method. At the end of the day, what matters is what the image looks like. Is there information in the highlights and in the shadows? How much resolution is there? Does the image "feel" right? Does the image seem "over-sharpened"? How far can you push the exposure and maintain a clean image? How is the color fidelity? The net result of all of these questions gives a more accurate description of image quality.

Just one other thing to add to the list: How does the camera roll off at the extreme highlight end of the scale? I would rather have a camera with 10 stops of latitude with a smooth film-like roll off than 12 stops with a more abrupt clip at the highs. It's incredibly difficult to fix an image where the highlights are posterized because the red channel clips before the green, etc. You don't see this happening with film but you see it all the time with the CineAlta. It will be interesting to see how the Red handles this scenario.

This is one of our best traits... creamy rolloffs.

200x cf speeds are slightly over the 27mb/sec required but since this datarate isn't set in stone and doesn't account for audio, metadata and overhead, don't count on it. however, 266x cf allows for a nice sustained rate of 40mb/sec so i don't see why that wouldn't work either.
