dritz Posted January 11, 2008 Share #1 Posted January 11, 2008 Advertisement (gone after registration) Hefty title, yes. I use VueScan to produce raw scans as DNG files. Capture One LE (4.0) obviously reads M8 DNG files, but will not *see* those produced by VueScan. I'm new to C1, so I hope there is an obvious and easy fix. They do load into PS via their Camera Raw interface. Thanks. Link to post Share on other sites More sharing options...
Advertisement Posted January 11, 2008 Posted January 11, 2008 Hi dritz, Take a look here C1 support of DNG files produced by Vuescan. I'm sure you'll find what you were looking for!
sandymc Posted January 12, 2008 Share #2 Posted January 12, 2008 Dean, I don't have experience specifically with VueScan DNGs, but it is a known issue that Capture One does not implement a full DNG decoder - they only implement a DNG encoder capable of reading files as produced by specific cameras. You can try running your files through CornerFix with the Capture One compatibility mode settings on. It will warn about "unsupported camera", but might work.....

sdai Posted January 12, 2008 Share #3 Posted January 12, 2008 Dean, I use Silkypix to edit DNGs scanned from Vuescan. Lightroom also opens VueScan DNGs. Link to post Share on other sites More sharing options...
rob_x2004 Posted January 12, 2008 Share #4 Posted January 12, 2008 What is so hot about DNG format? No Im not having a dig, I am asking. Link to post Share on other sites More sharing options...
sdai Posted January 12, 2008 Share #5 Posted January 12, 2008 What is so hot about DNG format? No Im not having a dig, I am asking. That's the RAW format Vuescan uses, apparently it would save Ed Hamrick a lot of unnecessary work to develop his own proprietary format. Link to post Share on other sites More sharing options...
rob_x2004 Posted January 12, 2008 Share #6 Posted January 12, 2008 Its an adobe format isnt it? What advantages over other formats? Link to post Share on other sites More sharing options...
sandymc Posted January 12, 2008 Share #7 Posted January 12, 2008 Advertisement (gone after registration) Adobe created the DNG format. Its advantages are that its open, so anyone can implement it, and its very flexible - it will support just about any kind of sensor you can imagine. It's problem is that Adobe didn't specify a "minimum implementation", so some vendors have built decoders that can only read a small subset of the full DNG format. Broadly, Adobe products will read any DNG file, but outside of Adobe your mileage will vary. Sandy Link to post Share on other sites More sharing options...
rob_x2004 Posted January 12, 2008 Share #8 Posted January 12, 2008 Why not use tiff? Link to post Share on other sites More sharing options...
sandymc Posted January 12, 2008 Share #9 Posted January 12, 2008 DNG is just a superset of tiff; it uses all the same tag definitions, etc. DNG just adds the fields necessary to be able to store raw data; tiff can't do that. Sandy Link to post Share on other sites More sharing options...
dritz Posted January 12, 2008 Author Share #10 Posted January 12, 2008 Another reason for it, is that I can do the adjustments in the productive environment provided by Lightroom/PS (alas, not C1). The VueScan interface for making adjustments really stinks. However, it does give great scans, and the upgrade and support policies are great, as is the ability to transfer the license between platforms and scanners at no cost. It's just not particularly friendly for making scan adjustments. It's a shame, as the UI should be the easy part. Link to post Share on other sites More sharing options...

It's just not particularly friendly for making scan adjustments. It's a shame, as the UI should be the easy part. Let me get this straight, because I'm confused like Rob on this... I have a Nikon 5000, which I used Nikon Scan for and it's pretty good. I do have a copy of VueScan as well, which I hardly ever use. Are you guys saying I can scan with VueScan and capture RAW scanner data then take it into ACR or LR (or C1 with a conversion, maybe) and fix things like WB in post? That would save me a lot of time, it's true...because an unadulterated scan would be faster than creating a TIFF. But you'd lose all the scanner's proprietary sw for dust and noise control or colour management, correct? Thanks in advance for someone willing to explain this...

Jamie, In my short experience with VueScan's DNG files in ACR, the advantages (WB) are less then with digital files. There is also Silverfast that does have a nice color temperature correction in it's main display and will provide you with more color correct files then VueScan's display. That advantage of course will diminish if you get more experienced with VueScan. I found it a hard way... Harald Link to post Share on other sites More sharing options...
carstenw Posted January 12, 2008 Share #13 Posted January 12, 2008 DNG is also a container format, right? The data that is stored in the chunks does not necessarily have to be in a standard format, and to my knowledge, no camera manufacturer has published full specs, so each cameras format has to be reverse-engineered to be supported, even by Adobe, but also by Phase One.

carstenw Posted January 12, 2008 Share #14 Posted January 12, 2008 Dean, you might try running the files through Adobe's DNG converter (yes, DNG to DNG does something...), and perhaps this would then work. Link to post Share on other sites More sharing options...

Not really - it is possible to embed "private data" sections in a DNG, which you couldn't decode without knowing the data format - this is what the M8 MakerNotes are. But most of the data, including the EXIF, calibration data and raw data is in a standard form; I've never seen a DNG that had the actual raw data in anything other than the standard Adobe documented form.

rob_x2004 Posted January 13, 2008 Share #16 Posted January 13, 2008 For teh digital guys your raws files contain the raw data. Exif is still contained in the then converted jpg, (and tiff?) By the time you reach jpg/tiff from raw format your priority is end use, and you have done your editing and tweaking. So where does DNG prove an advantage in practice, or what do people find advantagous? For scanning you are saying the scan settings are saved in the scan file? When does this help? I am still a bit lost on the whole DNG thing. Link to post Share on other sites More sharing options...
sandymc Posted January 13, 2008 Share #17 Posted January 13, 2008 One way to look it is the following: DNG is the only format that gives you the original raw data and "instructions" on how to turn it into a viewable image (the calibration data), all in a documented open form. A tiff isn't the original data - it's been interpolated for one thing. A manufacturer's raw file contains the raw data, but usually not the "how to convert it" information, so you need a raw developer program that understands that camera specifically. Because the DNG file has both things, all you need is a raw developer that understands DNG, not one that understand your specific camera model.

rob_x2004 Posted January 13, 2008 Share #18 Posted January 13, 2008 Ahh ok. But the calibration data, or the processing instrucions would be written and bear that manufacturers hallmarks. The raw info and Leicas instructions on how to process it would be different to another manufacturers raw sensor data and process instructions, and which presumably you can adjust as you chose to modify the image? Thanks for your perseverance Andy. Link to post Share on other sites More sharing options...

That's right. The only exception is, if you create a DNG from a Nikon or Canon (or whatever) raw file via Adobe's DNG converter, what you are getting then is actually Adobe's ACR calibration.

JHAG Posted January 13, 2008 Share #20 Posted January 13, 2008 I'm sorry but I don't see, in VueSca UI, where you set it for DNG. In "Output", you only have the choice between TIFF and/or JPEG. Reading the "Help", I have this : " In the Output tab un-check all the options except for Output > Raw file" There is no such an options under Output Tab. I tried all settings, ticking and unticking "tiff", "jpg", etc. I run the last Pro version (8.4.55). Pretty annoying… _______ My apology : doing my homework on Google, I found it in the prefs : ticking "Enable raw from disc" Sorry guys Welcome, dear visitor!
