For several many years i’ve been recommending all of our viewers to convert RAW documents due to their digital cameras to Adobe’s DNG structure.

Inside my DNG vs natural piece from 2010, We stated why using DNG over natural had feeling – it simplified file management, contributed to small applications (as soon as squeezed or any time enclosed JPEG impression measurement was actually paid off) and appeared like a sensible way to future-proof natural records. But as energy passed away, high quality products were launched i established checking out more post-processing solutions, I realized that DNG experienced a good number of biggest downsides that made me forego they. In this posting, i’ll revisit the DNG formatting and increase a few of simple includes on the reasons why it may not end up being the optimal solution that We once imagined it actually was.

Let’s have a look at some circumstances cases to discover just what advantages and disadvantages the DNG type has compared to RAW files.

1) DNG Conversion Process Boosts Workflow Experience

Whether we choose to transform my favorite RAW applications to DNG upon importance or at a further level of your energy, the conversion procedure throws an enormous problem on my transfer some time best issues simple workflow. While switching lightweight RAW data files from lower solution cameras happens to be barely obvious, changing something over 24 MP takes a large amount of hours. Incorporate a choice of creating 1:1 previews in addition processes and that I might be placed and waiting around ages before my own technology before I am able to at long last get started on post-processing imagery. Remember that DNG conversion process is not a simple process – the DNG converter mustn’t best backup and create EXIF data, but it addittionally must build a JPEG review to save to the DNG file, if you do this (which is always a good strategy, since imagery is generally previewed easily). With regards to the dimensions of the data and its own determination, this could just take years, particularly if you are actually taking on a large number of artwork.

2) Drive Area Concerns – Do DNG Truly Protect Area?

The DNG structure is far more handy than a natural file, as it enables you to firmly controls the sore file conversions procedures and identify sale selection. When dealing with uncompressed RAW files, DNG certainly does save a lot of space by converting huge uncompressed RAW files to losslessly-compressed RAW files. This alone can result in 50percent or longer in area cost savings. Also, there is an option to generate small JPEG previews, which results in additional space economy. If there is no need full-resolution DNG files, there’s even a choice for lossy compression, with the ability to reduce overall megapixel calculate. So you could probably avoid wasting room by using the DNG formatting, supplied your grasp the ramifications of these issues as lossy compression and down-sampling.

However, if you are smart regarding your video cam adjustments, space savings provided by the DNG structure tend to be more or significantly less minor. There isn’t any good reason why you need to actually throw uncompressed RAW in your digicam, hence just dont – always utilize the lossless compression strategy instead. In the event you that, the space preservation from DNG when compared to natural will likely be lower. Used to do a check extend with NEF artwork that I switched from simple Nikon D810 to DNG. With medium-size JPEG previews, the space financial savings amounted to about 15% and when we performed full-size JPEGs, that multitude obtained decreased to 10-12percent. Due to the cheap cost of storage these days, these quantities will not be one thing I can feel really stoked up about, specifically contemplating my exhausted your time changing those files and taking into consideration all the other negatives for the structure mentioned in piece.

3) Short DNG Format Interface

Although Adobe was pushing difficult to result in the DNG format open and commonly implemented for quite a while today, it looks like not too many organizations in fact offer a goddamn about DNG. Regardless of a few organizations like Leica, Ricoh and Samsung, every one of the large kids like Nikon, Canon, Sony, Panasonic, Olympus, Sigma and Fuji proceed disregarding DNG and forcing their branded sore forms. As well a number of DNG “ignorers” isn’t simply for digital camera vendors – many post-processing software products around either please do not read DNG whatsoever, or read it defectively, creating DNG a lot less of good use than it actually was built to take initial put. Any time you exposed a converted DNG file in items except that Adobe tool, you could find yourself dealing with extremely slower making time period, weird colorings, inability to see metadata and all various other conditions. Admittedly it is all definitely not Adobe’s fault, with offered enough paperwork on DNG, managed to get royalty-free or even proposed DNG to become owned by a standards looks, if needed. But it proved that other programs basically would not have confidence in the DNG structure using because vivid of the next as Adobe assumed it’ll need, hence assistance for DNG has become really restricted this means that.

Ergo, at the moment of your energy, would certainly be locking yourself to Adobe equipment in the event that you utilize DNG formatting, as rest provide restricted to no assistance for this.
