Ahhh... sorry, too quick to respond. I am on and off here doing some household chores - apologies

Not sure what app you use to edit your TIFF's, but what additional processing/editing would be needed with RAW?

Have a search for "the Brenizer method"... basically you take lots of photos like a panorama and stitch them together to give you the look of a camera with a much larger sensor.

I use FastStone and really old Elements 2 . All I usually need is straighten and sharpen. 10secs per image

Please see entry in " Chaos " for an example

Re: shooting .tif files

Just as technology gives advantages, sometimes, so does a little research. Rather than re-invent the wheel, a search of old Internet postings from 2001-2003 pointed out to me that even high quality jpegs can be better than tiff files, at least with cameras of the e-1's vintage.
Which is disappointing, in a way, as I imagine that one day the latest and greatest software might not include raw processing engines for older cameras? I like the universality of tiffs, but I guess the range of control just isn't there. That being said, modern software makes raw processing extremely easy, even for a photographer like me who could just as well archive everything in jpegs. It would be nice to have a non-proprietary archival format that any software could read, perhaps the .dng format is the way to go? Will dig into that Luminous Landscape article and edify myself.

Thanks for all the good thoughts on this subject.

Re: shooting .tif files

Well said, just beware that Jpegs are not a Lossless file, so never to be used for archive material, As I know to my cost, they deteriorate with use.

We learn by our mistakes.

Re: shooting .tif files

IIRC. the orf files have a 12 bit resolution while on checking the TIFF is 8 bit lossless and the jpg is 8bit lossy

Ah, eight bit tiffs, that is the one piece of the puzzle I was looking for, and explains a lot. Thank you, Chris.

Re: shooting .tif files

I have an E-1, don't think I'll ever sell it, because of build quality, layout of the controls and takes Tiffs. Regarding this file format, it has (and still may be) the format preferred by quality publications, magazines etc, because it's by default 16-bit, doesn't degrade every time you make a compressed copy of the file (Lossless) unlike a JPeg, even when on the lowest level (1) of compression. Adobe's DNG format, is the Raw equivalent, inasmuch that it is a 'Universal' Raw file format. Some cameras now offer the DNG format as well as the manufacturer's own Raw file format. (This means the file isn't just 'tied' to a particular manufacturer's in-house Raw software.)

Tiff files are often bigger than Raw ones, because the compression logarithm used, 'stores' the data which is stripped out during compression, to reconstruct the file as it was, when opened up. A Jpeg, when it compresses a file, 'throws away' the data a Tiff keeps, and every time you save a copy/duplicate of a Jpeg, even more compression is applied ... You can see this happening by just getting a Jpeg, noting how big it is, then save the file again, and then look at the size of the resulting file ... you will find it is smaller! Tiffs were never designed to be web-friendly (size wise) although you can use them this way, its just that people will get seriously 'Peed off' with down loading a 10+ Mb file instead of one which is maybe 500k!

Many publishing houses and commercial printers because of the printing presses they use, still demand Tiffs because their machines can process Tiff files, but not DNGs or Raws. I don't think it's a file format that's going to 'die off' or be abandoned for a few decades yet!

Re: shooting .tif files

I shot TIFF on the E-1 for quite some time and some of my best looking shots came that way rather than JPG or RAW (either Oly Studio, Lightroom or RSE). If I shot the E-1 again I would go straight for TIFF - if you like what the E-1 image processor does for images and don't like what JPG compression does (I don't) you can do little wrong with TIFF. You also don't get to play the colour rendition lottery with RAW developers which is either a benefit or a hazard depending on your PP style. I wish I had it on the E-5 still. Not sure about the E-400 - have to check when I get back home.

Re: shooting .tif files

Just for the sake of the whole 8 bit vs 16 bit thing...
If I use processing software that generates 16 bit tiffs, the resultant image (from an E-1) is about 30MB.
Straight out of the camera, E-1 tiffs are about 17MB, which strongly suggests, at least to me, the E-1 tiffs are indeed 8-bit.
Which also suggests that a 12 bit orf is a more flexible option than an 8-bit tiff, though I've yet to prove that to myself.

Re: shooting .tif files

I've just looked up the spec for Tiffs on the E1, they are indeed 8-bit, not 16.

Re: shooting .tif files

I don't think any of the bit depths of TIFF versus RAW are in dispute, nevertheless I have not as yet seen a developed ORF from my E-1 which I could call noticeably or significantly better than the TIFF versions I used to use irrespective of bits (per channel remember). The argument which says that 16-bits per channel is not so much of an improvement over 12 bits as you might think as the least significant 4 bits carry very little information applies equally to 12-bits versus 8-bits per channel. Factor in _any_ form of lossy compression to the raw files and there is your small advantage eroded :-)
