I'm a software developer, not a designer, I usually have designs provided by my clients before the work begins. It seems the designers always want to provide the designs in
.psd file format, is this a good (industry standard) practice?
The designs in question are for either websites or desktop/mobile software applications.
As a developer I find it easier to work with vector graphics (Fireworks / Illustrator), I find them much easier to slice and manipulate.
To be honest, I thought Photoshop was for editing photos, not for designing software. Is this statement correct?
