p.1 #1 · Why don't DSLRs output TIFFs?


Sometimes you like the in-body processing that your camera provides for JPGs but you don't want to be stuck with 8bit JPG files for post-processing.

Since JPGs are limited to 8bit, wouldn't it make sense for camera makers to provide other output options that are not so limited while still providing the on-board RAW processing?

For example, can't cameras output lossless 16bit TIFFs? TIFF files are well understood and a lot of software already understand it. TIFFs are also the basis for many proprietary RAW files anyway so this should not involve too many changes in the camera firmwares.

Many times I shoot RAW and then spend a lot of time getting back the original camera JPG look when all I wanted to do in the first place by shooting RAW was get a lot of latitude for correction of exposure errors. 16bit TIFFs would give me a lot of that lattitude back while preserving the native camera processing, right?

What do you think?

Because camera makers are loathe to start a new war on RAW vs TIFF.

Actually, as far as I know, Canons raw files are some kind of tiff format with special tags for writing specific data.

A normal TIFF has the gamma curve applied so you lose all the linear sensor data --> little latitude. You can 'massage' the file a more without getting posterization but you still have a lot less data than in the RAW file.
Also, dosn't RAW files processed with Canon DPP look pretty much identical to the jpegs that Canon DSLRs produce? I don't know about other brands though.

Huge file sizes with corresponding hits to memory card capacity, processing speed, and battery life? Interpolating the RGB color data from a color-filtered monochrome sensor basically triples (even more when going from a 12 or 14 bit RAW capture to a 16 bit TIFF) the amount of bits the camera needs to push around, while adding no "real" information. What camera companies should do is (a) support standardized RAW formats (e.g. DNG), and (b) work with photo software companies (Adobe, Apple, etc.) to generate camera-specific profiles/interpretation for their RAW files that preserve the distinctive look of their in-camera JPEG processing.

TIFF is an option on my camera but I don't see much point to it. When I want quick & easy I use jpg, when I want a 16-bit file I want to work it and raw gives me more flexibility.

TIFF is an option on every Nikon I've ever used, but pretty much useless...

Because it isn't 2002 anymore?

At the moment http://en.wikipedia.org/wiki/JPEG_XR (formerly HD Photo)looks good, I have posted in the past about wanting a file format that can handle in-camera HDR images without loosing so much data as jpg does.


Support for more color accuracy
In image and graphics representations, the color associated with each point in the picture (called a pixel) is represented as a set of numbers. Each color can be expressed as a combination of numbers that each represent the intensity of one of the components of a color (known as the channel) which consists of Red, Green and Blue (the three colors of light) color primary. Such a color scheme is called the RGB color model. Using an alternative set of color primaries, graphic files may treat the color of each point as a combination

TIFF is a final file format, output - very different from RAW. What happens when beter RCs come along? You're stuck with a 2012 TIFF....

Using the raw converter of the camera brand resolves this issue.

I know your views on this Ed and largely agree with the sentiment, but in this day and age maybe things are different. Read what the Sigma guys are saying about the Merrill files, for instance?

The 1Ds RAW output was TIFF. I doubt it was 16bit, though.

I'd be happy if the were a standard RAW, but everyone has to tweak.
