Camera RAW in GIMP
Hi there,
I wondered whether there was any facility within GIMP for the above. I am used to working with the "Open in Camera RAW" facility within Photoshop, which gives the opportunity to manipulate "Blacks", "Whites", "Contrast" "Saturation" etc in a WYSIWYG interface without the need to actually save the image at each stage. This is very useful in my situation where I'm trying to "bring out" features in generally quite flat imagery without necessarily producing "nice" end images. I know that GIMP isn't meant to be a replacement for Photoshop, but I'm trying to replicate what I do in GIMP so that I can provide it as a teaching aid to those who don't have access to Photoshop. I'm happy to clarify what I'm trying to do if it's not clear and apologise in advance.
Thanks

RE: Camera RAW in GIMP
For the time being, Gimp does only 8-bit/channel processing while raw processing is done on at least 16 bits (raw camera data is usually 12 or 14 bits). There is a UFRaw plugin to open you raw file directly in Gimp... but it's a bit of a lie because while you process the raw file you are completely in the plugin environment, and the data is transferred to Gimp (in 8-bit/Channel) only when finished.

So, in practice, instead f using the plugin, you can use any raw processing software you fancy, and save the output in TIF, PNG, or high quality JPEG and load it in Gimp for the fnishing touches. This lets you use the raw file processing software from your camera manufacturer, and the file used in between makes a nice intermediate backup.

Coming version of Gimp (2.10) will have 16/32 bit support, so this advice has a limited lifespan.

My personal preference is to use a separate RAW processor (Photivo in my case) then do final tweaks in GIMP.

RE: Camera RAW in GIMP
Thanks for that. Could you clarify what the YFRaw plugin is. Apologies, but I'm very much a new user and although I looked in the plug-in browser list I can't see any related to Camera RAW. Is it separate and I need to find it somewhere else? I looked at Photivo (recommended by Kevin) too, but that seems a bit too complex for my needs. I really want something simple, with a series of sliders in a single window where I can do the basic manipulation to see what shows. I realise this is probably very different to what the average user wants, but it's what I need.

RE: Camera RAW in GIMP
Fixed typo. Actually called 'UFRaw', both a plugin and a standalone app. A bit outdated now, but the only one working as a plugin AFAIK.

Delabratory https://code.google.com/p/delaboratory/ worth a mention. edit: and go there for some tips

There are precompiled executables for Win and OSX at http://www.partha.com/ - look down the left side.

This is in linux, a bit of an extreme example. It is non destructive, the controls are largely sliders and a bit simpler than Photivo (one of my favourites). Easy to go back and adjust a previous operation.

Might be worth a try.
