Adobe Sketch is deliberately simple and stripped back, clearly aiming to be as easy to use as possible, featuring a very small selection of tools including a digital Pen, Pencil and Eraser. Almost replicating the feeling of carrying a sketchpad and pen around.
While you can sketch on the iPad using your fingers it’s definitely worth investing in a decent stylus – this will dramatically increase your accuracy and general comfort.
Begin your sketch by drawing the horizon line. A low horizon tends to make your image look more dramatic as larger objects become exaggerated. Once that’s in place begin to loosely define the main areas of the image – use reference images if you get stuck.
Now start to refine the image, using your exploratory marks to guide you through the composition. Use bold shapes, diagonal lines cutting through the landscsape will give it a dramatic feel. You should always be thinking about how the lines will guide the viewer to the focal point.
Then choose a large brush and begin sketching in the values. If you haven’t done this before, try looking at you reference image in black-and-white and work from that initially.
Once you have finished your sketch you can save it to the cloud and open it later in Photoshop.
