Not to question you, but how is this possible?
I don't get why Shangarah is getting messages like in Morse code, while he has been al the more helpful when anyone asks about anything he can supply some tips for. And very long tips in many ocasions I have to say. I am almost sure I picked this link in this very list , and I found it most basic and most useful info about what is Raw file, which still seems to elude many. http://www.digitalfocus.net/sections/views/WhatisRAW/WhatisRAW_1.htm >From Raw data, you then make your choice to go for a 16Bit TIFF file or an 8 Bit one , or just a jpeg. Basically the RAW file will be about one third of the final image's full size, so you can always use this Rule of Thumb to estimate camera's file size( 6Mp cameras will deliver 18Mb tiff files, and so on) and the best advantage of this is both the obvious savings in space in the CF cards, and more useful yet, is the speed of recording of data to the card. This" buffer" capacity is the limiting factor to create DSRL cameras with bigger and bigger file sizes, and the Canon 1Ds( 11Mp Raw, 33 Mb Tiff) has already a limited "bust rate" of 3 files per burst, compared to the 1D that has a Burst rate of 16 files before the camera has to stop and save data to the card. The Kodak 14n , with yet a larger file, will have even slower rates, maybe 2 files per Burst, maybe less. I understand future firmware updates could- in theory- improve on this initial limitations and achieve better performance, but don't take my word for granted. Canon D60 still has a reasonable burst of 8 files, and I would say it is about the same rate for all cameras under the 6Mp range. Keep in mind that the burst rate is independent of the frames per second capability of each camera. Thus, the D60 shoots 3 fps (frames per second) and 8 fpb (Files per Burst). The D1 shoots 5 fps and 16 fpb, and this is the reason it is the preferred machine for sports /action photographers and photojourmalists. Both Canon 1Ds and Kodak 14n future owners, have to keep in mind these features and adjust their workflow prior to shooting , to this limiting conditions. That is the reason they are suggested as ideal for Advertising, catalogs and the like. Time to go back and look for the Cartier Bresson's "decisive moment" while shooting. Of course, I am saying all this, based on the basic idea that you purchased the fastest available CF card reccomended for your camera, so file transfer speed is NOT dependent on the Card. 16x Minimum I would say, 24x / 32x ideal. The Photoshop Plug In to deal with Raw files was presented by John Knoll, one of the original creators of Photoshop, in the Expo in NY and I would guess, taking into account the Beta state of the code, that it could be ready to go by February( this is my guess, maybe it comes earlier), and it is not going to be a free download either, but anyway much less expensive than the Phase One software and with the ability to recognize files from different cameras, something Phase one is reducing to a minimum, by reasons only they can understand. Better for Mr Knoll. All the best.
