No, you don't need new prints. The old prints are fine.

Oh, interesting. Does your screen have another option? Eg HDMI?

Does it give an error message when you try to rate? There are three methods for rating. Are none of them working?

Are they on your internal hard drive as usual?

Wait, what? How can you not be comparing to prints? You can't calibrate without print comparison.

Whoa, that sure is weird. How many photos are you comparing? How old are the prints?

This is a tough one all right! Thankfully he's looking pretty much directly at the camera, so it might be possible to fix one side, then copy it and use it for the other. To that end, try these three layers: Download PSD Then use the Handyman method to fix it further, to make it as perfect as possible in the circumstances. Then Stamp Visible and use for the other side. You'll need to flip it, but of course keep a copy of the iris not flipped, otherwise the catchlights will be mirrored.

Are you sure it's only skin tones? What about other colours in the red, orange and yellow part of the spectrum?

Simplify it for me. Are you saying your screen doesn't match your pro lab prints?

Then it really sounds like a weird graphics card glitch, I reckon. However, if that's the case, it's out of my league. I'm going to move this post into Brian's area. @Brian, does it sound like graphics card misbehaviour to you?

But then, after that period, it goes back to being correct by itself? Without you doing anything?

Wow! And how long does the whiteness last for? A few seconds?

Ok, let's plug the desktop screen into your laptop and calibrate that. If it calibrates successfully, we'll at least know that the calibrator is still ok, and works ok with the Mac OS.

Do you still have your desktop computer as well?

When does it do this, exactly? Just randomly?

Hi Brenda, take a look at the troubleshooting section at the bottom of the Spyder 5 Pro instructions. They're not identical, but should give you some clues to try. Let me know if anything helps. How long have you had both the calibrator and the laptop?

How did you go?

How did you go?

Plenty more yet.

It doesn't matter. It absolutely does.not.matter. Your master files can be 300, 240, 72, 89, 426, 138265, 9, etc. It's completely irrelevant. It only matters when sharpening for print, and you'll learn about that in the Sharpening Class.

@Kendra?

As part of your general workflow, do you mean?

@Jodie Williams?

Nerds will chew your ear about PPI vs DPI, but for all practical purposes, they're the same thing, yes.

Excellent. So yes, do exactly what they say. Give them a Level 11 quality Jpeg file, make sure the resolution is 300ppi, but make NO change to the image size. Send them the full-res file that you camera took.
