Hello,

I just have two questions about the future of the implementation of GEGL into The GIMP:

1. I read on different websites, that in future it will be possible to open RAW image formats of different camera manufacturers natively in GIMP without the requirement of additional software. Is this true?

It makes sense for our product vision and there is nothing technically difficult about it, assuming there is a library around that does the grunt work, so yes eventually GIMP will be able to do this. The usual disclaimer still applies: If you want to make sure this happens, help us with it. Right now there are no work planned explicitly for this.

2. Is GIMP going to support (also save to) the PFM file format http://gl.ict.usc.edu/HDRShop/PFM/PFM_Image_File_Format.html and will it be possible to make HDR information?

If someone writes a plug-in for it, then yes. Nothing the current members of the core team plans to do though AFAIK.

In fact GEGL is already tied to libopenraw which is a Raw can-opener written from scratch. Unfortunately, libopenraw seems to be discontinued by its developer, so the future perhaps lies in libraw which is dcraw turned into a modern library with multithreading support and all that jazz. As soon as GIMP starts using GEGL loaders, someone could write a loader via libraw.

There is nothing special about PFM what would make it difficult to support this file format in GEGL and, later, in GIMP. Judging by some projects, creating a PFM saver is a few days work, if not less. One just needs to sit down and actually write code. That's all.

If you don't consider a plug-in additional software, then you can already do that today. The difference with a GEGL-enabled GIMP is that you can then work in the higher color-depths that the RAW format offers. Today the RAW image is converted to 8bit per color channel on import into GIMP.

Sorry but I would consider this solution quite inadequate as higher color depths account for much of the leeway expected from using RAW image formats in digital cameras...

Which only means that a GEGL enabled GIMP with appropriate input filters is the only way forward in this respect. regards

Fortunately ACR, smart objects et al. are not the only acceptable way of dealing with Raw files :)

Well, if you ever looked at the UFRaw Import Plug-in, you'd know that it gives you a lot of control over how the conversion to 8 bit is done. So you already get most of the benefits of the RAW format. It's just somewhat uncomfortable that you have to do all the color and exposure correction at the import step.

Sure.

The problem is that I recently read about the scaling problems in any non- linear colour space and as a result have tried scaling some of my images in a 16 bit linear colour space - with stunning results. So UFRaw helps with the first problem of doing the conversion but 8 bit GIMP is messing up things later in the editing process... For the moment I am living with the results but now knowing how much better they can look without having to compensate late in the editing process having a workflow which would start with the 14 bit depth my camera provides per colour channel and never drops to a non linear colour space before the final save to JPEG would be preferred and I hope that a GEGL enabled GIMP will do so in the forseable future... regards
