Photoshop: How do I keep 1x and 2x (for retina display) images in the same document?




I just read on an article about designing for iPhone retina display that you can keep the 2x images in the same document and use a Photoshop Action to scale up the 1x to see how the larger version will look. Other than creating a separate canvas, I'm not sure how this could be done? Would the action be designed to scale up the entire canvas, including all contents, to the larger pixel dimension?


As a secondary question, I'm looking for retina-ready icons for a tab bar at the bottom of the app I'm designing. The only appropriate one I can find is bitmap, and looks blurry compared to the retina-ready vector image to the left of it. Would it be easier to design one like this from scratch or how could I otherwise go in and "clean up" the image to the left to make it ready for retina display? 


Thanks so much in advance for any advice with these two (admittedly, beginner) questions.

When designing for a variety of resolutions you want to scale down, not up. Do your design in a @2x resolution (640 x 960 @72ppi) and for the @1x assets you duplicate them to a new document (preferably) and scale them down by 50%. You can set up a Action script for this also to make the process go by faster. To learn a bit about Photoshop action script you can have a look [HERE](https://www.youtube.com/watch?v=BRpPGiGXcHc).


As for your second question, [HERE YOU GO](https://www.dropbox.com/s/sczltvow7jgtfiy/iPhone%204%20GUI%20PSD%20Retina%20Display.psd). The "reload" symbol you were after can be found in that Retina asset sheet, a sheet that is very good to have for anyone who wants to design for iPhone.
okay, from an iphone i see the problem. make sure you don’t have anything on too high of a pixel measurement regarding width as well as make sure none of what you have on position other than auto is sticking out. hope this helps. :wink::+1: on some cameras, there is a setting in the menu screen to adjust the brighness of the screen. i would also suggest just using the viewfinder to take pictures as well. hey thibaut,

i believe what you want to try is adding is a rectangle object that fills the rest of the screen but is a 0% opacity background. this may help to keep the object from resizing for the screen. double click in the figure to bring up the property inspector. make sure the units property is "pixels". then in the position property (expand it to see width and height), type in 900 for the width, and 100 for the height. if that still doesn't work, make sure the resize property is set to "on". thanks for the info joe. as it happens i can confirm this; i was teaching on a workshop yesterday and one of the delegates was using a win10 high-res display (a retina display mac booted into win10) and we saw exactly that.

the work around we used was that pixel units seemed to work fine; text beca… Then it shouldn’t be a problem to set the InDesign Transparency Blend Space to RGB. Also when you export for screens don’t use a PDF/X preset, they are designed for press output. Use the Export Output tab to convert the ID doc to sRGB.

Have you tried resetting your Preferences? (restart Photoshop and directly hold Cmd-Option-Shift)? >

You seem to be using the Windows Photos App, which is not color managed, and will not display correct colors.

Lightroom is color managed, and will display correct colors, as long as the monitor profile is correct.

This difference in color is more pronounced if you have wide gamut monitor, in which case you have to use only color managed applications to view your work.

Bridge and [Irfanview](http://www.irfanview.com/) are both free and color managed (you have to enable color management under Settings in Irfanview).

On Windows 10, the Windows Photo Viewer is apparently still color managed, but it's hidden somewhere. Do a search for it.

A paid option is the latest version of ACDSee (20).

The color space you set in the camera only affects jpgs (and the jpg embedded in the raw files), if you shoot raw, it doesn't matter which color space you choose. hey [@rapha](/u/rapha) , could you try these changes on your mobile mode? this suggestion stems from the fact that your cart takes up the whole height and is really narrow.

the result i get is the following:
