This is the best solution I can offer ...

Add a Channel Mixer adjustment layer, go to the Blue output channel, and change from 0/0/+100 to 0/+80/0.

Then invert the mask, and paint loosely onto the purple areas.  Hopefully it will blend well enough to get away with it.

Yes, I have yet to take your raw class but I will be doing so soon hopefully. Should I send a SOOC crop of the area?

This has nothing to do with the class.  Just make sure you do your noise removal exactly as outlined in that article.

It goes without saying that you must never commence any Photoshop work until your raw processing is completely finished.

Oh gosh, this is tricky.  May I see a closer crop of it?

Sure, I can do that.  May I use your photo?

Look, it probably won't make any difference, but since you're in desperate straits, you'd better try it.

Ok, we could get extremely technical about this, but let's try the easy way first.

Add a Channel Mixer adjustment layer, click "Monochrome", and enter 0/+100/0.  Then begin carefully masking to every ball.

Then, you can roughly draw a marquee selection around a ball, add a Solid Color layer of a colour you desire, and change its blend mode to "Multiply", then Cmd Opt G to clip it to the Channel Mixer layer.  If there are any other balls you want of that colour, roughly paint on the mask over those balls too.  Then make a new layer for the next colour, and so on.

Wait, what?  The Do Not Adjust one should have been the very first one you used, wasn't it?

Great.

Have you tried varying this setting with each calibration?  http://www.damiensymonds.net/wp-content/uploads/2015/12/38.-s5p34.gif

Come on Valentina, help me out here   What colour would you like the balls to be?

the hair on her face (next the her ear). Is there a tutorial you can direct me to?

May I see it up close?

Yep, jpegs for sure.

When people talk of "magenta vs yellow" it makes me suspect they're myopically looking at skintones only.

Can you promise me you're looking at ENTIRE photos when you're telling me that the print is yellow?

No, come on, these are crazy noisy.

Oh boy.  This is going to be a challenge.

Go ahead and do your raw processing first, then post it again for me.

Which Spyder4 is it?

Either way would be fine.

Oh gee, the whiskers will make it more complicated, but we'll see what we can do.  Go ahead and do your raw processing as usual, then post this 100% crop again for me.

What single colour would you like them to be?

And what will the photos be used for, exactly?

Gee, this is a fat lot of BS.  They don't need PDF files.  Just send jpegs.

No, you've done exactly the right thing.  Your edited master files must be in sRGB, as usual.  Converting to CMYK is simply part of the output process, just before saving as jpeg.

Thanks! I have just read both posts and I am using Photoshop. Should I just ask them to be more specific about the CMYK requirement or do you need a specific information?

No, that's all.  You just need to ask exactly what CMYK profile to use.

There is no text or added shapes in my pictures, do I still need to keep the adjustment layers as layers and don't sharpen the flattened image before saving the file as pdf?

It's just photos?  Nothing else?

How many images did you try?  Sometimes these kinds of problems are specific to only one file, and sometimes they're widespread.

By the way, you must NEVER use the Eraser tool.  Ever.

I think the Handyman Method should do ok.

Bleed: 6mm, no crop marks, no print marks

Do I set the bleed as extra 6mm (right or/and left)

This is an excellent question.  I would assume that they mean you should allow 3mm extra on each side, for a total of 6 extra millimetres.  So your entire file would be 303x426mm.

1 hour ago, Valentina said:

or should I be prepared that 6mm within the 297mm will be cut out?

This is extremely unlikely, but to be safe, you should make sure that nothing you don't wish to lose is closer than 6mm to the edge.

Color: CMYK

What about the color? Never worked on a CMYK and not sure how to set it.

They haven't given you enough information yet.  Have you read this?

What software are you using to design this file?  If Photoshop, please also read this.
