Astropad, like all Apps that create a bridge between computer and iPad, has a desktop version that provides the necessary connection. Upon initial opening of the Mac App, one has to decide what percentage of the computer screen should be allowed to appear on the iPad. Because of the nature of our complex work in Photoshop, it is advised to mirror the entire screen when possible. Connection between the Mac and the iPad can be established either by using a cable or wirelessly, assuming both the iPad and the computer are connected to the same network. As usual, the wireless option requires a fast and stable internet connection, so it's not always an option when working in the field. Naturally, the main question is: why would the artist prefer taking the computer AND the iPad to the field to provide a field drawing when he/she could just work on the Companion? There are many possible answers to this question.
- Working on the same file on the very same computer from start to finish, and thus simplifying the drawing process, certainly has a great appeal to anyone who has ever worked remotely.
- Moreover, the ideal studio computer is far more powerful than either the Companion or the iPad. Often it is the only machine that is capable of providing the necessary processing power for a large format multi-layered file without significant downscaling.
- The iPad Pro can be a lightweight drawing canvas that feels better to hold than Companion. With a lengthy cable, the artist is able to work on the iPad Pro either standing or sitting, while the main computer can be hidden in a dust proof corner.
- Many artists consider or already own a MacBook Pro as their main computer when working in the studio. Investing in yet another non-upgradable computer running a different OS that has to be constantly updated and managed can be discouraging and costly. On the other hand, having a lower cost, low maintenance "external drawing canvas" such as the iPad is the closest one can get to using a touch screen Mac in the field.
(1)To provide the same drawing experience on the iPad as we are used to when working with the Companion, we have to disable line previews and enable the cursor in the Mac App.
(2)The same effects can be applied directly from the iPad App, along with the option to reserve more processing power for drawing as opposed to easier scrolling.
(3)Eight Photoshop commands can be set up as short cut buttons. Present setup shows the Survey’s standard setting for fieldwork with mostly painted surfaces.
(4)Shortcuts appear on a sidebar when using Astropad. While shortcuts can be operated by finger or stylus, the Apple Pencil becomes the only input source when operating Photoshop.
(5)Additionally, the most commonly utilized hot keys, such as Shift, Control, Option and Command, can be added to the set of onscreen buttons, allowing the artist to execute quick commands.
Nevertheless, using Astropad as a substitute for Photoshop on the iPad is not always unproblematic. While it succeeds in documenting decorated surfaces where less precision is needed from the artist, such as painted elements, it fails miserably in an attempt to use more sophisticated Photoshop tools, such as the Pen Tool. Still, it is worth considering as an option if only for the fact that with the help of Astropad one is able to work on final layers in the field, which may be a time saver at the end.
WHAT TO READ NEXT
Changing the arc of a curved line is just as hard in Photoshop as it is on paper - assuming the artist is drawing freehand. The artist has to pay attention to keeping the smoothness, the thickness, and the sun-shadow transitions of the original line while carefully adding and removing extra brush strokes.
The best way to make local enhancements over smaller areas is by using the Burn and Dodge tools. The Burn tool can be used over light areas to make the pencil lines appear darker. When the artist uses the Burn tool, he/she has to be very careful
