Update: DNG is supported via ExifTool as of Version 1.6 of LRTimelapse.

I just tried LRTimelapse for the first time and was surprised that it did not handle DNG files. I thought the standard was supposed to be open so I posed a question to my local photography forum and got this reply:

He can just grab the DNGs' embedded JPEGs or read/write via Exiftool.... Nothing to do with "a proper Java API".

I wonder if this will be of any help?

Good luck. The idea and execution looks very promising!

Thanks,

David
Surprised to find it doesn't work with DNG. Only no that because of this post. Lucky I came across it because I convert all my files from propitiatory and also use a Lecia now and again which captures RAW as DNG.. Perhaps it should state rather than RAW + JPG that the plug in works only with propitiatory RAW files and jpgs, as my DNG's are RAW files.

Is there a reason for this? Can't find anything on the site. The xmp data is the same irrespective of wether it is written to the file (as with DNG and jpg) or to sidecar files (as with propitiatory)
@Pete does it work with your Leica DNGs?

@all: since adobe embeds the xmp data in the converted DNGs I need the ability to read/write that data from/to dng. Adittionally I need to read the embedded preview.
Using an external tool for that would not be a nice solution in terms of platform independency and so on.
I didn't find the time to dig deeper into that DNG issue yet, and it's not on top of my priority list to be honest but I promise I will look into it again when I have time.

Here is a response to my thread on another forum regarding the DNG standard:

"The standard is open. Here's my evidence.

www.adobe.com/products/dng/pdfs/dng_spec.pdf

Adobe will tell you the binary format of a DNG file. That's as open as it gets.

A Java API is a programming library written in a specific language [hopefully I'm being clear, rather than patronising; please excuse me if you find otherwise] that provides a method for a Java programmer to access the file without their having to read the actual spec. Similar APIs would be needed by programmers in C, Lua, COBOL or anything other language you can think of [RIP DEC STD 32]. And any reasonably competent programmer ought to be able to read Adobe's spec., and produce such an API library.

In contrast, a closed standard would be one in which the binary file format is not publicly available. This forces programmers who wish to fondle a file [or protocols] contents to reverse engineer the data. This is a process that is fraught with both technical and occasionally legal difficulties. Examples of closed file formats that have been reverse engineered by third parties include [or used to] Microsoft's Office files [OpenOffice], and the SMB file access protocol [SAMBA].

There's an interesting middle ground in things like the Lightroom SDK. I think its the case that Adobe don't openly document the format of the Lightroom catalog. But they do have a downloadable API, the SDK, that allows anyone with the appetite for such things to access the contents of the catalog in a programmatic way."


I hope this may be of some use to you when you get around to it. In the meantime keep up the good work!

That's it for me on this topic. I'll leave it to the professionals now.

I haven't tried any time lapse with the Leica (not mine, just borrow one now and again), not the best tool for then really! But I will give it a go some time.
It also seems that LRTL has problems with previews in other RAW formats. Tried it with some RAW's from a GF-1, the software works fine, shows all the various lines and data, but no preview of the image itself.
If you want some samples of the Panasonic RAW format then let me know. The G series Lumix cameras are ideal for shooting timelapse, particularly as they work well with old manual lenses avoiding a lot of the flicker problems in the first place.

You may want to note that your PayPal donate button takes you to the German PayPal site and this doesn't seem to recognise my UK log in. No problem with any other international PayPal system except the German one! Otherwise I would have made a little donation as I think your plug in is already very useful and has great potential.

Please send the files to support (at) lrtimelapse.com and I'm going to look into it.

Could you explain the issue please? The paypal language of my account is english and normally there is no problem with international donations... It would be a pity if technical constraints would prevent you from donating ;-)
I'll send a Panasonic RAW file.
This is the screen I get from your donation panel, it will not accept my PayPal login.

Pete, that's interesting - because here everything is in english although I'm in Germany. Nevertheless you should be able to enter an amount and donate. The errormassage basicly says that you didn't enter an amount.

Gunther,

I had exactly the same issue, I got only the german version, I just took your email address and used the us version of paypal to send the money and that worked. Must be something when the link is clicked or maybe because it is being forwarded through a German based site.

Hi! I'm just installed the software for the first time, and it see the DNGs I have on the folder, but I understand by this post that this program can not be used with DNG files? Have to keep the CR2 from my Canon 5D as the native RAW?

Thanks.
