EdD Posted January 17, 2019 Posted January 17, 2019 I seem to be having a case of brain freeze. I've taken an image and converted it to B&W. So far so good. After a bit of sharpening an adjustments to the colour channels (via the BW filter) everything looks as I want. Exported the image and then when I open it in Finder or attach it to an email the solid black areas are 'mottled'. I remember something about colours showing up with red or blue areas to indicate if they're oversaturated but it's been a long time and I can't remember what to do or even if this is what's causing my problem. Any suggestions? I've attached a small sample to show what I'm getting rather than solid black. Thanks Ed Quote
firstdefence Posted January 17, 2019 Posted January 17, 2019 Have you tried using the Background Channels to create a Greyscale Layer, you can use red, green, blue or all three to get a nice b&w Could you also upload the image unedited? if you don't want to do that could you upload a partial image by making a selection copying it and using File > New from clipboard to create a new file you can use to upload, before you save rasterise the layer.

firstdefence Posted January 17, 2019 Posted January 17, 2019 Hi @EdD what are you trying to achieve with this image? Use the Develop Persona to get detail back in the image, once you have a workable image you can go to the Tones tab and select Black & White. On the tones tab you can pull the red back to about -20 to get a bit of detail in the background trees.

EdD Posted January 18, 2019 Author Posted January 18, 2019 Where I'm getting these strange results is when I export the image. Inside AP it looks fine but the file I output has the 'grainyness' showing when I try to open it in Finder or send it through email. Any idea why that's happening? Quote
walt.farrell Posted January 18, 2019 Posted January 18, 2019 What format are you exporting? If JPG perhaps you're seeing compression artifacts, since that format used a "lossy" form of compression.You might need to choose a higher quality setting, to get a larger file. Or choose a different format.

EdD Posted January 18, 2019 Author Posted January 18, 2019 Thanks for the help guys. I restarted the process with the RAW file and did the conversion, twig removal and sharpening and couldn't reproduce the problem - it worked just as I'd originally intended. Must be the universe getting back at me for past indiscretions or maybe one of my cats 'helped'. Either way the problem has disappeared and I haven't found a way to make it happen again so I'll just carry on. Ed Quote
