Wrong picture size for Fuji S3 pro

    I have the same issue with the Fuji S2, though I think it's more explanable. With the S2 it's always been questionable whether it really is 12mp or 6mp. Fuji claimed that their processing was able to pull out 12mp, but many doubted that it was anything more than interpolation. In my own tests I have been unable to really conclude anything.

    C1 thinks that it (the S2) is a 6mp, as does Adobe Camera Raw.

    The S3 is a different story as it has 6mp of \"S\" pixels, and 6mp of \"R\" pixels for a total of 12mp. (I'm sure you knew this all anyway).

    In any case, it seems like it should process at 12mp. My guess is it's based on their S2 algorithm and thus is only 6mp.

    Of course I have to say you're a lucky @#$% to have one of these! 😄

    I'd be interested to know if Fuji improved their software, which frankly is inexcusably awful, for the S3 (and if so, why we can't get it for the S2!).

    The RAW file has 4256x2848 pixels, believe it or not. Just set it to this as your output file size (under \"Preview\" on the Mac version) and you'll get great results. It's the opposite of the Photoshop RAW converter, where you set the image size before loading it in to the program.
    Remember, every single-shot, single CCD digital camera uses Bayer filtration for color rendition (with R, G or B filters over each photo site) and is interpolating to some extent, even the H25. As I understand it, Fuji skews the pixels on their SCCD (on the S2) out of a standard right angle matrix and then assigns values into the diagonal spaces in between, then makes this part of the RAW file. If you set the camera to save as anything other than RAW, you get the smaller 6mp images as a maximum. The S3 is similar but with the two types of pixels at each site, and these are high and low light sensors which combine to calculate a single value for each photosite.

    I tried your suggestion, but then the image size % went to 141%

    Also, the exif info pop up box on the image browser shows the file size as 3000xx1992.

    Are you saying it is okay to enlarge the image?

    Maxhirez,

    Interesting. Unfortunately I can't try it because I have LE where I can't set the output size. Maybe some day if I decide to go Pro I can try it (big jump in price though). Seems to me that if it's capable the LE's S2 default should probably be 12mp, not 6mp when I think about it but...

    Honestly it isn't a big deal to me - 12mp is usually too huge for my needs. and I can always use ACR or Fuji EX I guess.

    As long as I've got your ear, I'm wondering, do you really find the S2 12mp images really have more detail than an interpolated 12mp?

    Just wondering. Thanks for the response!

    I think so, but then again I bought the S2 with the preconcieved notion that it would be better than any of the \"real\" 6mp SLRs for the reasons mentioned. I do notice better results converting the RAW 12mpx files to tiff than converting 6mpx tiffs to 12mpx tiffs, even using special image enlargement software or the sequential 10% enlargement at a time trick. All it really comes down to is how the software reads the information from the chip, and I guess I trust Fuji to know its hardware better than Adobe or Gnu.

    Well, now I'm not sure. Which version of the software are you using? Most of the time, you set the new image size and then the resolution to get the bigger file. It makes sense that the 12mp file would be about 141% of the 6mp file (inverse squaring or somthing involved in the math) but rather than enlarging the image, let's think of it as making use of the extra RAW information Fuji provides with the capture. Like I say, it's just a clever use of geometry that allows these extra "virtual" photo sites in. My experience has all been with CO Pro 3.1 on a Mac in this area. I can't really speak to what the other programs allow.
