Fwiw, I'm still having this problem following the recent update. I just tried importing a .tiff, an old scan; applied the noise filter - looks great in preview, but then when I click the 'Apply' button, the progress bar moves across the page, then bang! - all the noise comes back. Very frustrating.

The iMac is ATI Radeon HD 4670 256 MB and the MacBook Pro is 2.4GHz Core 2 Duo with 8 GB RAM, NVIDIA GeForce 9400M 256 MB, OS 10.11.1

I'm using a Panasonic DMC-G6 Example at: https://dl.dropboxusercontent.com/u/282315/P1110967.RW2

I guess those of us who are having this problem should report our system specs, to help the guys at Serif trace the problem - mine is: 3.06GHz Core i3 iMac, 12GB RAM, OS10.95 And I can report that I get the same sort of problems on a late 2008 MacBook Pro running Yosemite. This is so frustrating - Photo is a great programme and I'd sooner use it over Photoshop or even Gimp, but with this problem it's not really possible to work with RAW. Furthermore, I just tried de-noising in the Photo persona, and what you get once you hit the 'Apply' button is not the same as what you were looking at just before i.e there is some noise reduction, but it doesn't look as good as it did whilst you were adjusting the settings - I can provide 'before' and 'after' pics, if you like... Something is clearly not right here. Perhaps the forum is not the right platform for this - is there a more official channel for bug reports?

No - I'm rather hoping for a response from someone at Affinity... Someone?

OK, so the link is broken even though i corrected the typo, so I've put it on YT here: https://youtu.be/D1t1pOADTZ8 Comments welcome.

Here's an example: http://www.wildfrontear.co.uk/AffinityRAW.mov Check what happens at around 0.46

Thanks, that's very useful, but my point is that that was exactly what I was doing, i.e. removing noise in the Develop Persona, and getting reasonable results, but then as soon as i click the 'Develop' button, all the noise comes back again! Is this expected behaviour?

I'm fairly new to Affinity Photo, so maybe there's something I'm not getting about the RAW workflow, but what actually happens when you click that 'Develop' button? Because I'm finding that often the actual image you get after you 'develop' is not the same as what you've just been working on, which makes no kind of sense to me. For example, I was editing a bunch of pictures that were shot in low light, hence a little noisy, and although I managed to clean them up considerably when working on them as RAW images, as soon as I click Develop, they're full of noise again! Actually, it looks more like some artful attempt at introducing grain, but that is not the effect I'm after. I can post examples if you like, but maybe it's just something I haven't understood about the workflow, in which case, please enlighten me! Cheers Roger

The screenshot attached shows the same RAW image imported to (from L to R) iPhoto, DxO Optics Pro and Affintiy Photo; how come they look so different? And which one is right?! It's not the best example, but in general RAW images are looking much worse when imported into Affinity when compared to other applications- very noisy, or like they're being displayed at a low colour depth or something. Is there something I'm missing?
