Excellent collection of file type handlers and effects plugins for Paint.NET. Not the fastest ever at loading camera RAW images (takes about 5-8 seconds to load a CR2 from my Canon 30D), but it’s definitely helpful.
According to the website, it supports the following image types:
| *.dcr | DCR | Digital Camera RAW Images |
| *.dng | DNG | Digital Camera RAW Images |
| *.eff | EFF | Digital Camera RAW Images |
| *.mrw | MRW | Digital Camera RAW Images |
| *.nef | NEF | Digital Camera RAW Images |
| *.orf | ORF | Digital Camera RAW Images |
| *.pef | PEF | Digital Camera RAW Images |
| *.raf | RAF | Digital Camera RAW Images |
| *.srf | SRF | Digital Camera RAW Images |
| *.X3F | X3F | Digital Camera RAW Images |
| *.crw | CRW | Digital Camera RAW Images |
| *.cr2 | CR2 | Digital Camera RAW Images |

I loaded the plugin, but when trying to open .nef it requests additional commandline arguments. Maybe I’m just blind, but I’m not finding any documentation anywhere that provides such arguments? Do you know where I can find that?
I wish I knew; I’ve only tried this with Canon RAW (.CR2/.CRW), not Nikon RAW (.NEF). Have you tried contacting the author of the plugin?
Hi, I downloaded and installed the pulgin but I am still not able to open .cr2 files using the paint.net software. I may be missing something but is there any documentation on how to open and work on .cr2 files after installing the plugin.
Thanks

try converting to dng via adobe free dng converter, not sure whether it’ll work, but it saved my butt when SRW Samsung raw weren’t supported in my HDR software

This doesn’t’ work for my cr2 raw picture from my Canon T2i. Make the pictures purple and black.
Thanks for the tip. These two plugin packs worked well for me.
