Macbook Pro Sharpening.

Hi all. Haven't been on the forums for what seems years. Would very much like to hear from anyone that uses a MBP/Retina for editing of aviation images. Main issue (only issue tbh) is sharpening. As the screen resolution is so much better than the previous Satellite I had, when it comes to sharpening, the Retina screen makes any image seem sharp without actually applying any sharpening. Have been told to change the resolution but even then it seems difficult to judge. Any of you had the same issue? What resolution do you use? Thanks!
Spencer.

I use 2880 x 1800.

Avoid posting "Me Too" messages. These are messages that are posted by people who agree to a point being discussed and post a one liner, "me too!", "Good post Jim!", "I disagree" or similar message. This takes up time as readers must sort through these messages which have no real value to the group at large. Any message containing nothing more than a line or two of text is probably not worth posting.

You use the full resolution then. What (on average) values do you use for sharpening? At 1600px wide, and image on the Retina display barely takes up half the screen. As such it appears sharp (perfectly sharp in fact) without any sharpening. How do you gauge it for viewing on a pc for example? Not everyone has such good resolution so my concern is I am not sharpening correctly. What I've noticed is if I apply even a low amount of sharpening it tends to bring in jaggies, due to the image being so small on the Retina screen.
Thanks
Spencer

My main editing computer is my 13" MacBook Pro with retina, except for both screening and editing Airliners.net images. For that I have to hook my computer up to my 6 year-old HP LCD screen. Honestly it's a pain in the ass and its holding me back on a desktop/iMac upgrade, but until this site adapts to the shift in screen technology I wouldn't trust editing for Airliners.net on a retina screen. If I'm in a pinch I'll scale down the resolution but as you noted, that doesn't help much.

Hey Spencer I mentioned this on your FB page but think it got lost.
Because of the greater pixels per cm sq if you view your edited shot at 200% in PS it will look very very close to how it will look on a low res monitor.
I have tested that on my 27" IMac Retina as I was having exactly the same problem when I first got it.
The 200% works well.
To test open an image you have edited on your old screen then open it on the Retina one at 200% on the new one.
View them side by side and think you will find that they will look basically identical.
Meaning if you sharpen at the 200% view it will give you a good image to view on a low res screen or site.

Thanks for the tip! I'll try that out.

Just to add some detail my comparison was on a 2010 IMac at 2580 side by side against the new 2015 Retina running at 2580 Hidpi.

If your running a new IMac an excellent post on the way Apple had to tweak the display to allow for the still many low res viewing websites still out there.

My wish would be for minimum res of 2500 in all the hard core photo sites.
A few reasons.
Firstly 1280's etc hide many flaws in images shot with the current swarm of hi res sensors on today's market.
Ie everyone gets swamped with a mass of images many of which would fall apart under close scrutiny of hi res screening.
Yes you get less usable images but the detail and quality of a great image is there for everyone to see.
At the lower resolutions the astounding detail available today is lost in a sea of 1024 pixel images which show none of the capability of the camera, glass or photographer.
With 4K and 5K the new viewing standard companies like Apple have to come up with fixes so that a 1280 pixel image is actually a viewable size by doubling its native resolution to make it Viewable at any level.
Obviously this changes the viewing perception of the image considerably.
Technology in monitors cameras etc has left the Internet in its wake and our ability to view beautiful hi res images in sizes unimagined only a few years ago.
The big players need to catch up and jump ahead or they will be left behind surrounded by the 1024 pixel swarms ile the world wants 3000 to 4000 pixel highly detailed beauties.

You mean like the people who buy 36 megapixel cameras to fully process them and upload exclusively to Instagram?

Thanks a lot Darren. Will check the 200% out later.

I've got the same issue Spencer, and haven't figured out anything but an imperfect workaround. I'm using the "looks like 1680 x 1050" resolution on my 15" MBP Retina. I usually use Smart Sharpen in Photoshop as needed when editing a high-res file, and then when I resize to 1200 or what have you, apply USM with amount = 12%, radius 1.0, and threshold 0. It's not exactly a perfect method but seems to work decently well to consistently sharpen the low-res file without going overboard. I love to edit the high-res files on this computer but low-res is definitely more difficult.

Here are the settings I use (or close to them) when sharpening for a.net:

Royal, that's for a screen in the default mode, I assume? That's after cropping as well? Thanks mate.

That's with the screen at 2880 x 1800. Right now I am using a finished size of 1400 wide.
