Dedicated camera just for scanning

[Alan Edward Klein]

because DNG is Adobe Lightroom’s native format. DNG also lets you store the image as a CFA array instead of full RGB, which means smaller files. DNG also stores all of your edits in the file non-destructively, so you can pass just the DNG file around and all the edits go with it. AND, DNG is in fact a TIFF file.

So your scan is a "raw" tiff with the edits listed separately that LR can then interpret or remove in my machine's Lightroom v.6 licensed rather than a tiff where all the edits are built-in and non reverseable?

yep. To be clear, the edits in question are edits done in LRs Develop Module. The process of generating the initial positive image from the raw camera scan involves a fair number of operations that LR just doesn’t do, at least with my process. My goal is to deliver a positive image that looks and behaves just like any other raw DNG with the full toolset of ACR/LR at your disposal. What you get is a raw positive image that works exactly the way you’d expect it to in LR, just like if you shot that same image on a digital camera and pulled the raw images into LR and had LR convert them to DNG files. The difference you shot it on film and have the actual physical image.

On my own scans, I save all of them in Tiff, whether Epsonscan made any edits during the scan process or not. Then I use LR to edit. Assuming I could save scans in DNR (don't know if I can with Epsonscan), what advantage if any is there when I open LR?

for anything Epson scan generates, there isn’t any, but you can tell LR to convert your TIFF files to DNG and gain a fair amount of portability for your LlR edits. If you keep them as TIFF files, LR will store what edits it can in the standard tiff metadata, and the rest in the LR catalog file. If it’s DNG, it stores everything in both places.

ive had a number revisions to my color since you last sent film to me. Btw, if the skies are too magenta for your liking, it’s a pretty easy fix to ever so slightly either increase the green or reduce the red using the LR tone curve for the highlights to nudge it more towards greenish blue and less towards magenta/purple.

interesting comparisons. NLP seems to be too aggressive when it comes to pushing highlights to clipping.

Thanks for your feedback. I have a few more rolls of Portra 160 and a roll of Ektar you may be seeing one day.

And thanks for the tip about the LR Curve tool. I have been using the LR Curve tool for controlling lights and darks, but for some reason, I have not been using it for color corrections. I have tried using the basic green:magenta slider but adjustments toward the green side usually resulted in the neutral gray tones (concrete, etc.) shifting too much to green before the magenta sky was fully corrected. The magenta seems to somehow be firmly associated with the blue sky, and even after using gradient and brush tools to limit the correction to the sky, I have not been able to get the skies the way I want them. I have been using Lightroom since 2016, and I agree that this should be a "pretty easy fix" but, so far, I am still struggling with it. However, I just played around with the curve tool set to the green channel, and I think that will be more helpful than some of my previous attempts.

Wouldn't that take up twice the data storage?

 

[Adrian Bacon]

Yes, however it’s metadata, not image data. It’s not even a megabyte per image, more like a couple hundred kilobytes.

Hi Adrian,
Are there any other file storage formats that share similar advantages. I avoid the Adobe products - mostly Corel here.
I note that I can read DNG files, but I can't write them.

Hi Adrian,

The short answer is use TIFF files and your software of choice. The longer answer is:

Technically, DNG files are TIFF/EP files, so really any software that supports TIFF files and can read/write TIFF/EP files could do the same thing. My code uses the open source tiff lib to generate my DNG files. The only difference between LR and other software, is LR writes the Develop module stuff that is specific to LR to a set of TIFF tags that are specific to ACR/LR. Any software can read/write those tags and do the same thing that LR does. It's all in TIFF meta data tags that everything can see. There's no secret going on under the covers. Adobe isn't being some evil corporation that wants to lock you into their secret file formats. They are simply providing superior software functionality and user interface layered on top of standard file formats that are widely supported by lots of code libraries. Why other software out there isn't following suite and doing the same/similar is beyond me. If LR were to go away tomorrow, I'd be beating down the door of their next closest competitor and demanding that they start implementing the same/similar functionality that LR has, and use the same tags that LR does, and/or go off and implement my own version of LR that does the same thing.

For example, a DNG file in my LR catalog, as seen by the absolutely awesome and freely available exiftool:

The juicy Lightroom bits are down in the [XMP-crs] tags bit. There really are no secrets with what's going on with this file. If I really wanted to, I could use exiftool to write in some changes to the XMP-crs structure (say add some points into the 2012 tone curve for example), then go into LR and tell it to re-read the metadata for that file to pull those changes into the develop module. It would pull them in and they would show up in the Tone Curve panel. Why other software doesn't really do this is beyond me.

Thanks for your feedback. I have a few more rolls of Portra 160 and a roll of Ektar you may be seeing one day.

And thanks for the tip about the LR Curve tool. I have been using the LR Curve tool for controlling lights and darks, but for some reason, I have not been using it for color corrections. I have tried using the basic green:magenta slider but adjustments toward the green side usually resulted in the neutral gray tones (concrete, etc.) shifting too much to green before the magenta sky was fully corrected. The magenta seems to somehow be firmly associated with the blue sky, and even after using gradient and brush tools to limit the correction to the sky, I have not been able to get the skies the way I want them. I have been using Lightroom since 2016, and I agree that this should be a "pretty easy fix" but, so far, I am still struggling with it. However, I just played around with the curve tool set to the green channel, and I think that will be more helpful than some of my previous attempts.

The basic white balance temperature and green/magenta sliders are global. I'd only ever use them to set the overall tone, then either use the tone curve tool, or the HSL/Color tool, or the Color grading tool (or some combination of those) to touch specific areas. Each of the panels has a little gear in the top left corner of the panel. If you click on it, you can then put the mouse pointer over the image area you want to select, click, and move the mouse up or down and it'll auto select the right slider, or put a point in the right spot on the tone curve. This is very useful when doing HSL or color grading stuff as you don't have to guess which slider to start with.

LOL... No,... copy/paste, change font. I actually forgot I spotted out so many spots on that particular file, but there they are in the metadata.

All that being said, It would be so awesomely useful if other image editing tools even implemented a small subset of the ACR/LR Develop module. The white balance, basic tone, tone curve, crop and color tool panels would standardize interoperability and instantly make things more portable between software. These are all standard issue image editing operations that most if not all image editing software does, so why everybody does it their own way and/or bakes it in, just isn't doing their users any favors. There's no technical reason not to.

 

[fmueller]

Can you share some results in full res?

Sorry, been away. I'll post a link tomorrow morning.

 

[SrMi]

for anything Epson scan generates, there isn’t any, but you can tell LR to convert your TIFF files to DNG and gain a fair amount of portability for your LlR edits. If you keep them as TIFF files, LR will store what edits it can in the standard tiff metadata, and the rest in the LR catalog file. If it’s DNG, it stores everything in both places.

I cannot convert TIFF files to DNGs. Both Lightroom and Adobe DNG reject conversion of TIFF files. How are you doing the conversion?

[Edit: the only way I can convert is to invoke Export as DNG from LrC, after having imported as TIFF. The logical step to convert would be at import (Copy as DNG), but that is not possible.]

Uncheck "Only convert Raw files" in the Source Files section.

Thank you. I was hoping for a way to convert TIFFs to DNG upon or before import. I assume you have written your own code to do that. Converting after export (Convert Photo to DNG) leaves both tiff and DNG files on disk.

I’ve written my own code to do that. For your use, just import the tiff like you normally would, then once it’s in LR, select it, and do convert to tiff from the menu system, just uncheck that checkbox and it’ll do it.

After seeing all the metadata in your post, what advantage really is there for the average photographer to store scans in DNG rather than tiff. SInce no one handles the metadata other than Adobe, it seems I would be better off sticking with simple tiff scans. Once I do the LR edits, I create a final tiff and/or jpeg final image file. At least I could open them up with other than Adobe software that I use like Photoshop Elements and Windows picture and Irfanview. Some of these might open DNG (I don't know as I haven't tried), but many might not. I:d rather stick with a more universal format like tiff or jpeg.

if you’re in Adobe’s ecosystem, DNG just works, if you’re not, then just use tiffs.

 

[MattKing]

I can read DNG files in my Corel and FastStone software, so you don't lose any ability to share if you send them out.
