Click on it and set to 16-bit TIFF.Īs I said, I am a ACR rookie 😉 thanks to Capture One. To setup a 16-bit TIFF workflow: when you open a raw file in ACR, there is a hyperlink-like text at the bottom of the window that reads like "AdobeRGB (1998), 8 bit, 3916 by 2634 (10.3MP), 240 ppi" with an M8 DNG. Besides some fancy features in ACR5, not much gain in an upgrade to CS4 for you as far as I can read from our discussion. Some ACR4/ACR5 remarks: Both allow 16-bit TIFF workflow, both support your GX200, both support batch processing in Bridge and PS. Ho-Humm, I suppose that means an upgrade to CS4 at £160 is required. Of course then in PSE6, half the tools then don't work on 16 bit TIF's. If I use PSE6, which I normally only use for teaching students, I have the option of 8 or 16 bit TIF's. One strange thing with ACR is that if I use ACR within CS3, it only gives me the option to convert to 8 bit TIF's. ACR does not produce such good TIF's from my Leica M8 as C1 and I would guess that when I get the profiles sorted on C1, it will be better for the GX200 as well. The latest version of 5.2 only works with CS4 or PSE7 (Windows only). BTW, I find I cannot use the latest 5.2 version of ACR with either CS3 or PSE6 for Mac but am currently limited to V4.6. Until such time as I get Colorxact ICC profiles sorted out to use C1 V4.5, that will do OK. You can of course, batch convert in ACR from Bridge (I use Bridge CS3). Are you referring to converting with DNG Converter? I am more of a rookie than a geek on ACR, but regarding batch converting, I thought both Adobe DNG Converter as well as ACR has sufficient facilities.
So even if I get an ICC profile to use on C1, I am not 100% sure that would be a total answer. Of course, ACR is a total pain to use, as it has no proper batch conversion facility and each image has to be converted separately. A fully Ricoh GX200 enabled RAW decoder such as Adobe ACR, will apply this data at the conversion stage of each image and indeed when I look at an ACR (version 5.2) conversion of a GX200 DNG file within Photoshop CS3, it looks a bit better than the C1 conversions. It would appear that Ricoh encode specific additional image data for each image and insert this in a compartment of the DNG file. I have been doing quite a bit of additional reading on DNG RAW files. I have looked at the website and that looks a very interesting possibility. I do not have any experience with this service but you might find it useful. They offer a reasonably priced target and free online processing software. As an alternative, you might want to look at Hopefully someone in your area has that option available to you. As you might now, profiling of a camera requires an image taken with that camera of a reference color chart and processed with profiling software.
