As far as the 100% vs 200% goes, I think something odd is happening, maybe with wordpress. There is no stair stepping or edge artifacts visible in Light Room 1:1 view on my Retina screen.
Not surprising as a \"Retina\" resolution screen hides detail at 100% view as compared to a traditional resolution screen at that same % view. In essence, what you see at 100% on the Retina screen is like viewing at 50% on a traditional screen. This works out perfect when printing (as 50% view at 240ppi is about what you see in a print*) but when critically editing an image, viewing between 150%-200% is required to simulate what non Retina users see at 100%. Yes, confusing but one aspect of using higher resolution screens...
*50% view at around 240ppi on a traditional resolution screen (which is about half the resolution of a Retina screen) is roughly equivalent to 100% view on say a Retina Macbook Pro 15\" since it\'s screen has a native resolution of 220ppi.
OT (sorry) I don\'t know what you\'re talking about... I\'d love for you to explain it in a way I can understand.
Here\'s my problem with my Retina display. When I open a photo in Preview on my Mac Retina, it looks pixelated at 100% view (command+0). When I open the same file on my older Macbook Pro non-Retina, it looks fine, and is exactly the same size as it is on my Retina display.
I find that I have to view everything on my Retina one step below 100% as in, I press command and 0 then command and - (minus button next to 0 button). This gives me a slightly zoomed out view, and that\'s the only time images look sharp.
This pixelation also happens on a lot of websites, where someone uploads a say 800x1200 image and I\'m viewing it at 800x1200. No matter the DPI, quality etc. The second I go onto my old MBP it\'s fine.
So I don\'t know if it\'s a flaw in the programming of the OS, but I hate my Retina display. All my works ends up being done on my Thunderbolt display, which is just the HD display, and doesn\'t have this problem.
Do I have something set wrong? Or is this the normal behaviour you\'re talking about?
Preview will scale the image based on the setting in your display preferences. So, if you have set that display setting to make things appear larger on your screen (i.e. \"Larger Text\"), that could be the issue you are running into as it will basically magnify everything. If you use a \"Retina\" aware Adobe app (or other imaging app), open the same image in Preview and compare it to how the image looks in the Adobe app at 100%. It likely looks a lot smaller in the Adobe app since the \"Retina\" aware apps display images at the native resolution of the Retina mac. You can do the same test with a web browser as well (same image, side by side. One opened in web browser and the other in say Photoshop/ Lightroom at 100%).
By default, a 15\" Retina Macbook is set to scale images to mimic a 1440 x 900 display. That is actually half the resolution of the Retina display and will be in effect for most general apps (but not \"Retina\" aware imaging apps like Adobe Photoshop/ Lightroom which will still use the native 2880 x 1800 when displaying images). That is why the above exercise works.
Adobe LR and Photo shop are the only programs that work fine, but annoying to use when editing on the Retina.. The web and preview and other apps don\'t work right. I don\'t have any of my settings away from default. No enlarged text, etc.
If you view the same image in Photoshop at 200%, does it appear the exact same size as it does in Preview and in a web browser (pixilated or with issues) on the Retina Mac? When using a Retina display at the default settings, this is exactly the point I was making. At 200% in Photoshop on the Retina, that image would also roughly be the same magnification as when viewing at 100% on a non retina monitor. This is entirely due to the higher pixel density/ resolution of the Retina display.
