Each program in the Creative Suite by Adobe has crossover, but each of the programs- Photoshop, Illustrator, InDesign, Acrobat, Dreamweaver, etc- has particular strengths as well.
As designers, we have favorite programs where we feel we can express our ideas best with the tools that are offered, but there will be times when a particular projects demands that we stretch our wings and use the program we feel the least comfortable in because it offers the necessary features to best complete the assignment.
See the article below written on Design Festival by Tara Hornor for her thoughts on jumping ship and transitioning into InDesign.
Why Switch at All?
First thing’s first, why do you feel the need to switch over to InDesign in the first place? In most cases, you’ve been handed a project by a client that is in the .indd file format. Or, maybe you’re latest project is a multi-page publication.
InDesign allows you to define a layout and then gives writers the ability to change up the content on the fly without destroying your well-designed layout. Sure, you can try to design a 12-page publication in Photoshop, but you can be sure of one thing — the editors are going to come in at the last minute and want a bunch of new content added or cut out. This can completely change your layout and which text flows from one page to the next.
InDesign is going to be your best bet if you want to have quick control of the global document without having to mess with multiple documents in Photoshop.
Easy to Switch
Photoshop and InDesign are produced by Adobe, and over the last few years they’ve done a good job of making the two systems talk to each other. Adobe has gone out of their way to make the interface between Photoshop and InDesign as similar as possible. In short, you can generally open up InDesign and know what you’re dealing with pretty quickly. There are some software-specific tools, but nothing you can’t figure out by clicking around or doing a quick search for.
