I am having serious issues with photoshop at the moment in regards to the image size on the workspace. Its a 400x200px canvas at 72dpi and it comes up TINY on the workspace making it impossible to work with but it says its at 100%. When i zoom in the quality is decreased and i just can't do any work. Please see the screenshots below.

    You need to realize that there is no Problem.  You need to learn and understand basic digital image processing.  You need to understand pixels,  pixel size is  resolution Pixel density DPI the  there are displays that have a 96 DPI resolution and there are displays that have resolution above 300 DPI.    Displays can not change their DPI the are manufactured with a fixed size square pixel. Your image will display large on a low resolution display and it will display small on a high resolution display.  It comes down to Pixel size. 

    If you want your image to display the same size on both low and high resolution you need to have two versions of  your image.  One the has so many pixel for low resolution display and a second version the many times that amount of pixels for  high resolution displays.

    So basically 400 x 200 is tiny in photoshop but its the actual size that i want when uploaded to the web lol. How does one go about designing on something so tiny when zooming in and working just makes it so pixelated and hard to work with?

    Hi

    If your pixel resolution must be 400 x 200 then you can only zoom in to greater than 100% and live with the pixelated look. There are a couple of additional comments to that though:

    If you are designing with images such as photographs, many websites are designed to allow the upload of two or more images with different resolutions. The browser then shows the appropriate image according to your screen resolution. That way images can look correctly sized and sharp on Hi dpi as well as conventional screens.

    If you are designing with shapes then use vector shapes rather than pixels, which you can scale up and scale down without any ill effect. However, if you save as a jpeg, or png at any time then these revert to being pixel images.

    A quick web search turns up many articles on this but to get you started see the attached :

      Dave's excellent explanation is spot on.

      In other words, dopeantelope, there is nothing wrong here! You just have a very high resolution screen and this is what it does.

      What Dave did not mention is that all your other Mac apps, web and file browsers, image viewers - they all scale the image up. They do this to compensate for the small size, because otherwise Apple would be flooded with complaints and questions like yours

      Photoshop can't do that. It has to display accurately.

        What is your Display's dpi resolution.  Displays do not use image resolution they use their resolution.  400x200 Px would display 4"x2" on a 100DIP Display and 2"x1" on a 200DPI display and 1.33"x 0.66" on a 300DPI display

        it appears that my resolution is 1280x800 which says its the default for a mac. i've just tried changing this but it makes no difference.

        1280x800 is not DPI resolution it the number of Pixels your display displays.  Is your 1280x800px Display 30" or 6" in size.

        Is your 1920x1080 HDTV 65" or 32"

        At 100% magnification, each pixel in the image is mapping to each pixel on your monitor. 400 px by 200 px is quite small. Is that the size you need for the final output? If so, just zoom in a bit, not too much or it will become pixelated.

        Is this file destined for onscreen viewing?

        Hi, yes its for onscreen viewing. On previous versions of photoshop this has never once been an issue and the size came up perfectly normal. When i make an 800x400 image and put it online it comes up wayyyyy bigger than i was working with on photoshop and so all blurry and really terrible quality. I just can't work with it at all because of the quality on the screen but then also the quality when i upload.
