High capacity WORM tape cartridge for imaging

Tuesday, February 22. 2011

For use in cameras like this one with a slot for this media format. Caution: You can store photos in RAW only on this media and due to the storage method the media has to be processed on specialized equipment afterwards. However easy read out afterwards with minimal equipment. Important to know: The remaining storage can't be used for new images after the processing. Filling up media when possible. A tape media management to track remaining storage capacity appears as a sensible choice when used in professional environments.

Unfortunately the capacity is not very high by 2011 Standards. You will get at most 3000 dpi from this brand. If you give it a 16 Bit per color density, you get 3000*4500*6 = 81 MB per picture. So the capacity is about 3GB.

And have to struggle, to get this results. Most of my ISO 100 dia positives do not have 3000 dpi. I have tried some scanners at 3000 and the difference to 1800 is not that clearly visible.

It could be the lens, the camera (keeping the film plane) or the scanner. But i doubt it. I think, this type of film is limited to around 10MP per frame. Its rgb for every Pixel of course, not 50% green and 25% red and blue, like most digital slr's do.

Sure, the dpi is not very high (consumer grade film is comparable to about 10-12 Mpix sensor resolution), but dynamic range is higher than digital format. For professional film the resolution may be much higher. So the era of film is not over yet.

The resolution of professional film is not that much higher. And the dynamic range is higher, but this is already covered by the 16Bits per color.

The professional plus of film is the scalability. Making a bigger sensor leads to exponentially increased cost. A bigger film frame is only a linear increase. This makes a 6x6 film camera affordable, but a 6x6 digital camera unreachable for software slaves. Nearly half a years pay is not the type of toy i can justify to my wife.
