"So if I want the image to take up say 70% of the card, I calculate the
size so when it's taking 70% of a Retina screen it look good. "
When saving, which PPI should we be chosing.
I'm still stuck in the old "72dpi for web" which is the wrong use of
"DPI.. since photoshop is actually asking for PPI
If you take a great photo, resize to 2048X1536 px. then "save for web"
you still have to other options to set
I looked all over the web today... still confused.
AT photo.stackexchange we see this:

If your image is 240px * 240px at 240dpi, and you change the resolution
in photoshop to 72dpi, the image is still 240px * 240px and the quality
isn't changed. It is just a reference for if the image is to be printed.
If you're using an image onscreen you can ignore the dpi, it will only
ever display the number of pixels.
which begs the question: when saving for retina 2048 X1536: what PPI
should we choose on save?

I took the "ease the pain" path. I include 1 image that looks good on the
best resolution device and then scale it down. I use the iPad Retina for my
calculation. So if I want the image to take up say 70% of the card, I
calculate the size so when it's taking 70% of a Retina screen it look good.
Now when the image displays on a lower resolution device I scale it down to
70% of the current device size and place it where it needs to be. Now this
has one big downfall.....CPU time. If all there were was iOS then creating
all the sizes for the Apple ecosystem would not be too bad although lots of
work when the next gen comes out. With the veritable cornucopia of Android
sizes I determined that it would be an impossible task to have images for
all those resolutions. Now I did all this before there was rescaling in LC.
Back in the day I got Jacque's "You have to roll your own rescaling" reality
check. It's nice to see that rescaling is now in LC. I'm going to give a
whirl soon.
