![]() You will also learn how to easily convert your RAW files to DNG using both Lightroom and a free Adobe DNG converter. My guess is that PM does not correctly interpret the DNG resolution data (which is in the makernotes).In this article, you will learn what DNG files are and how they differ from the most popular image file formats. Weirder still when I then instructed PM to set the resolution to 300, it showed it as 300, but the underlying metadata (as inspected with exiftool) hadn't changed at all…īut it gets more funny: I then quit and reopened PM, et voila: the resolution once again back at 72ppi (at least this does explain why exiftool didn't find any differences this seems like a bug to me. What baffled me though was that in the file, the resolution seemed to be set at 300, but PM showed it as 72. It simply leaves the resolution at what's already in the file (which is good as you are just converting the data to another format, not change the metadata). Regarding the resolution, I did a little digging and from what I found, the DNG converter does not set this at all. Note: unless you have a specific need for this, you should never convert to Linear DNG! Linear DNGs aren't really raw files, but contain already demosaiced image data, thereby losing the ability to benefit from any future improvements in the demosaicing algorithms. Turn that option off and you should see much smaller files. You tell PM to have the DNG converter produce Linear DNG files. I am using the latest version of the converter with Windows 10.ĭoh, I should have spotted this right away. However, when using the converter via PM yesterday it resorts to the uncompressed DNG file increasing the file size to 30-40 MBs rather than matching the NEF size or less. In the past, when required, I've used the Adobe converter and set the preferences and it has worked very well compressing a DNG file as needed or not at all depending how the preferences were configured. Obviously, this workflow may be peculiar to me but I would have thought that a DNG ingesting conversion option in PM would benefit a lot of other photographers too.Ģ) This may not be the right place for this question. If there was a PM option to ingest and convert to DNG at the same time with the much faster XQD card system then I would likely find that very beneficial for the big events even if the process was longer than normal. If there is a break I will do a little selecting and then, after the medal ceremonies, send as many pictures as I can to the agency who require all submissions within 12 hours of the day's event finishing.īetween events, I have other small jobs that might be up to 100 images but they are not a problem and often require very little tinkering with. The events I attend are invariably 2 or 4 days and as long as 7 days for the Olympics with each day around 10 to 12 hours per day.īecause of the long days, I usually ingest into my laptop every couple of hours leaving the process to run in the background while starting again with a fresh card. I also backup to a separate portable drive while ingesting so always have reserve NEF images. I have been experimenting with converting NEF files to DNG using PM which is why I am a bit late in replying.ġ) I do tend to retain most of my images culling just the near duplicates and out of focus images, reducing 2k+ from a day's event down to around 1200-1500 for archiving.
