Adobe Photoshop Touch: how to use Photoshop for phone and tablets Sep 25th 2013, 23:01, by jmeyer One of the most exciting launches Adobe has announced in the past year was Photoshop Touch, the app that brings some of the best features of Photoshop for phone and tablet users. Tablets have huge potential for photographers. They are a great way of showing off your work to friends and prospective clients without having to carry a large portfolio case or computer, and there are some great apps that can make your life easier, by adding GPS tags to images, calculating hyperfocal distances, or even enabling a camera to be controlled remotely. Adobe has produced some superb mobile apps such as Photoshop Express for making quick, simple changes to images captured by the on-board camera, and Adobe Nav, which turns your tablet into a tool box to save screen space when you're working on your desktop computer. Photoshop Touch goes quite a bit further than Photoshop Express, giving you a pretty comprehensive set of tools and features (including layers) to edit images. It's available for the iPad from the App Store, and for Android tablets via Google Play, and it costs £6.99 for tablets and £2.99 for phones. Few are likely to switch to using Photoshop Touch instead of Photoshop CC, but it's a great platform for thinking through ideas and experimenting with images. You can treat it like a photographer's sketchpad. However, if you want to edit images when you're out and about, there's an impressive collection of powerful tools that give some great results, and you can sync your images and projects with your Creative Cloud account to carry on working on your computer when you get home, or share the results on Facebook. Google images The image search feature within Photoshop Touch is worth exploring. Just type a keyword into the box, and if you want, narrow the search using the drop-down list in the next field. You can specify a colour to search for by tapping the paint palette, or limit the search to images that are free to use. PAGE 1: Why use Photoshop for phone and tablets?

Sep 25th 2013, 10:59, by jmeyer Image size vs image quality is one of the great debates in the age of digital photography. In our latest cheat sheet we’ll illustrate the effects on your images at different settings to show you just how size matters! On most DSLRs, you get at least three levels of compression to choose from – the highest quality is 'Fine', the next-best is 'Normal', and 'Basic' is the lowest quality, and best reserved for emergencies. Your camera also gives you a choice as to how many pixels you want your picture to have. To choose the maximum number your sensor allows, select Large (L). Medium (M) produces images 75 per cent of the width or height, while Small (S) produces images half the width or height of the full-size version. We’ve illustrated the effects of this process in the infographic below. Simply click on the cheat sheet to see the full size version, or drag and drop it to your desktop to download. How to set image size and quality The process is pretty similar on most cameras. For the purposes of this tutorial we used a Nikon D3100 Info screen On a smaller Nikon D-SLR like the D3100, you need to press the 'i' button to display the Info screen, then use the multi-selector to highlight the quality ('QUAL') settings, top right.   Raw or JPEG? If you choose raw from the Image quality menu, you'll see that the Image size menu below is greyed out (RAW files are always shot at full size). To shoot JPEGs, choose Fine, Norm or Basic.   Image size If you choose one of these JPEG options, you can then use the Image size menu to choose the Large (L), Medium (M) or Small (S) image size, but see the box at the top of this page before deciding.
