Comments on: DNG Workflow / Part II The latest news about the top pixel wrangling application on the planet. Wed, 27 Mar 2013 13:18:59 +0000 hourly 1 By: Marc Rochkind Marc Rochkind Tue, 14 Feb 2006 17:56:03 +0000 Great column… I am thinking along the same track. Take a look at my web page (, where I talk about and have available for download an all-in-one utility that reads from the card, makes two copies, converts to DNG, and gives you a chance to verify visually before offering to delete. I would greatly appreciate feedback from anyone about this so I can work it into a utility that’s both convenient and reliable.

By: Jeremy Clow Jeremy Clow Wed, 19 Oct 2005 04:43:40 +0000 The flaw here is the converters inability to handle JPEG’s. I exclusively shoot RAW now, but before I learned what I was doing, I shot JPEG. How am I to archive those images? I don’t want to discard them, but now I have an extra step in my post processing. One more step, cuts into my shooting time.

By: Nick Rains Nick Rains Sat, 18 Jun 2005 04:40:07 +0000 Hi Jeff

Another thought occurred to me – if you point Bridge at the destination folder before starting the ingest proceedure, Bridge will thumb and preview each DNG file as it is written. This eliminates a step and two time consuming tasks can occur concurrently.

By: Mark Turner Mark Turner Thu, 02 Jun 2005 18:37:42 +0000 I’ve been following this DNG business with great interest, but haven’t made the jump to converting my files yet. The current articles are leading me in that direction, so maybe I’ll move soon. The prospect of going back and converting thousands of D60 .CRW files and re-archiving them to CDs is daunting.

I’m concerned about the suggestion to process raw files directly from the compact flash cards through the DNG converter before the original files have been backed up to some other medium. My own workflow involves copying the files from CF to the hard drive on my computer (either laptop in the field or desktop in the office), doing a quick review and rotation of verticals in BreezeBrowser, then burn a backup CD or DVD. Only then do I do a more serious edit to delete less good variations and renumber to fit my filing system. I just don’t trust having my digital originals stored in only one place before any software processing. Perhaps I’m paranoid, but I’d rather be safe than sorry.

I’m also not convinced I want to add more time to the “ingestion” process while running a laptop on battery power at 10 pm in the middle of nowhere when all I really want to do is go to bed to be rested for the next day’s shoot. It takes about 18 min per gigabyte to copy the files from CF to my laptop as it is, using a PC card adapter (Win XP on IBM ThinkPad R40). Five or more gigs of originals a day, and we’re talking significant copy time, plus burning CDs.

The DNG benefits of an open format and no sidecar files and are substantial, especially as more software supports it. I’ll stay tuned.

By: Daniel M Daniel M Wed, 01 Jun 2005 12:57:17 +0000 The utility that I use to transfer files form the CF to the system is able to ‘grab’ EXIF info to use it in the filename.
If I have files from 2 different days in a card and transfer with DNG converter, the date (dropdown) will be the same for all files. If the date was pulled from the EXIF, then each file would have the correct date.

By: Scott Jones Scott Jones Sun, 29 May 2005 18:21:39 +0000 Great articles. Only problem for me in using this as my “ingestion” utility from my CF card is that it does not transfer the JPEGs along with converting the RAW files. So if I have a mix of JPEGs and RAW on the same card, The DNG converter will not grab all all the pictures so I still have to go back to the CF card with some other utility and transfer the JPEGS.

I would suggest making the converter able to transfer all files to a designated folder while converting the RAWs.

Any thoughts?

By: Simon Iannelli Simon Iannelli Thu, 26 May 2005 21:48:13 +0000 thanks a lot for the great articles.

i agree with you that it is a great feature to convert directly from the CF. but i got a little problem. after the conversion and numbering i’ll maybe delete some shots an so i got gaps in my numbering. what now? renumber or leave the gaps? (or maybe i could explore my CF first with bridge, delete some shots and import and convert afterwards[this takes time i maybe don't have while])

uhm.. i’m not shure wich is the best solution. any suggestions?

By: Thom Hogan Thom Hogan Thu, 26 May 2005 15:21:06 +0000 When I talk about necessary software for digital cameras (most of which doesn’t exist yet), I talk about “hubs.” You need three: an ingestion hub, a processing hub, and an output hub. In a perfect world, they would be completely integrated; but in an imperfect world, photographers would tolerate them at least being aligned enough so that they were scriptable (on a Mac) or could be run sequentially (on Windows). (And if you haven’t already figured it out, the use of the word “hub” instead of “program” is intentional and implies something that can direct sub-programs into more complex and customized workflows.)

The problem with DNG Converter as an ingestion hub is that it fails Bruce Fraser’s (and my, and that of a lot of other photographers’) need for not screwing up the moving of data from the camera to computer. It lacks ability to deal with JPEGs, extract preview images, add IPTC data, identify sub-jobs, create automatic backups, and much, much more. Depending upon the client I’m shooting for, my image ingestion changes a bit, so it also fails in its ability to have me “mass configure” it to a particular client setting.

By: Nick Rains Nick Rains Wed, 25 May 2005 22:52:17 +0000 I am pleased to see this workflow put forward by one of the main protagonists in the digital world. I already use this workflow myself, almost exactly as described, and even went so far as to write a major feature for one of the camera magazines here in Australia about it, due out in the next edition.

You missed one benefit, if you use DNG as your main archive format, you only need to preview in Bridge once. All RAW edits are refected in the JPG previews embedded in the DNG file so you have a fully up-to-date previewed archive perfect for burning as-is to DVD.

DNG Converter is turning into Photo Mechanic! If you combine this workflow with the slideshow features out of Elements3, you have a pretty good clone of PM.

So, the wishlist:

1. Ingestion into at least 2 different folders at the same time.

2. IPTC templates to add copyright etc.

Wishlist for Bridge:

1. Option to turn off ‘previews’ and use embedded jpegs only. Editing is vastly too slow to make Bridge a professional tool for this task.

By: Philip L Philip L Wed, 25 May 2005 20:13:10 +0000 The issue of corrupted files, Jeff, does cause some concern and make one wonder whether converting right at the point of download is the best idea.

Although the pop-up warning dialog that the DNG Converter provides is no doubt very handy, and would likely allow for less chance that a corrupt file will go unnoticed, what if a file is corrupt and not discovered by the DNG Converter, only to be discovered later, after the file is converted to the DNG file format?

My question is, would you lose the ability of 3rd-party recovery software to get back the file. (I’m thinking in terms of if you were to do as you have outlined above, as opposed to archiving the *entire* contents of each card)


By: David Marx David Marx Wed, 25 May 2005 19:22:01 +0000 Dear Mr. Jeff Schewe,
I have been following your excellent articles on the Adobe DNG and wish to thank you for throughly explaining the uses for this valuable tool. One danger, though, that this article fails to mention in using the DNG as a “image ingestion” tool is that it ignores JPEG files. If you use this as a method for empyting a memory card rather than doing a copy using the operating system you will miss any images that were captured in JPEG.
I think that you are on the right track with this suggestion but that the DNG needs to include some of the features that Adobe already includes in its “import images from memory card” wizard in the PC version of Elements 3.0. (On a tanget Elements 3.0 has a ton of cool features like the side-by-side slideshow feature, and the backup utility that should be expanded and included in other programs.)
I fully support using the DNG to ingest images and love the way that it solves the file naming and sub-folders annoyance but this somewhat dangerous advice for photographers who shoot with a mix of RAW and JPEG on the same card. Thanks again for the great info on this tool.

–David Marx
