ICC profile for Ricoh GX200
I have just upgraded my small back up camera from a Ricoh GX100 to a GX200 in order to have RAW taking at a workable speed. My main camera is a Leica M8, where I take 100% DNG/RAW images, converting in C1 V4. I am a Mac not PC-Windows user and Ricoh does not supply RAW conversion software for the GX200 RAW/DNG images for Mac. I have been a Capture One user for some years, currently using version 4.522. I am very comfortable with C1 used for DNG's from my Leica M8. I would therefore like to use it for RAW conversion from the GX200. I cannot find anywhere, an .icc profile for the GX200. Has any forum member got one or more .icc profiles for the GX200 or even just a single daylight one that they might be prepared to let me have? Any suggestions of a company who would do one for me at a reasonable cost? I only have the simple not the Pro version of C1, so cannot do my own profiles. Any help appreciated.

Have you already tried CO4's DNG File Neutral profile? 0 -

Paul,
Yes I have tried the neutral profile and also some for other small sensor cameras. The results all come out a bit dull looking. If you just increase the saturation afterwards, they seem to go straight from dull to garish with no middle ground. I know from early experience with the Leica M8, before Phase One wrote a UV/IR filter profile and hugely improved their non-filter one, how much better the results were (then with C1 V3.7) using the various profiles kind people had written and posted on the Leica Camera User Forum.

Wilson,
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. Hopefully someone in your area has that option available to you. As an alternative, you might want to look at http://www.colorxact.net/
They offer a reasonably priced target and free online processing software. I do not have any experience with this service but you might find it useful.0 -

Paul,
Many thanks for that suggestion. I have looked at the website and that looks a very interesting possibility.
I have been doing quite a bit of additional reading on DNG RAW files. It would appear that Ricoh encode specific additional image data for each image and insert this in a compartment of the DNG file. 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. 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. So even if I get an ICC profile to use on C1, I am not 100% sure that would be a total answer.

Wilson,
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. Are you referring to converting with DNG Converter?0 -

You can of course, batch convert in ACR from Bridge (I use Bridge CS3). I had forgotten that. Until such time as I get Colorxact ICC profiles sorted out to use C1 V4.5, that will do OK. 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. The latest version of 5.2 only works with CS4 or PSE7 (Windows only). 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. 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. If I use PSE6, which I normally only use for teaching students, I have the option of 8 or 16 bit TIF's. Of course then in PSE6, half the tools then don't work on 16 bit TIF's. Ho-Humm, I suppose that means an upgrade to CS4 at £160 is required.

Wilson,
Some ACR4/ACR5 remarks: Both allow 16-bit TIFF workflow, both support your GX200, both support batch processing in Bridge and PS. 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.
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. Click on it and set to 16-bit TIFF.
As I said, I am a ACR rookie 😉 thanks to Capture One.0 -

Paul,
When I tried the batch conversion from Bridge to CS3 on my big PowerMac with 2 x 22 inch screens, there was the script you mentioned. On my Macbook, this does not appear, as it is hidden behind the dock and the window of ACR is not downsizeable to make it visible. The window on ACR conversion for PSE has a little pull down dialog box which shows 8 or 16 bit. I have downloaded CS4 this morning and been playing with it quite a bit. I am impressed with ACR5 and also the additional PS controls for M8 images I had already converted to TIFF's in C1. I have ordered Scott Kelby's book on CS4 from Amazon and only after I have read it and played with CS4 for the 30 days trial period, will I decide whether to buy it or not. I suppose compared to a new 50/f0.95 Noctilux lens for the M8, at a mere £5,000, CS4 upgrade is quite cheap!
