Frequently Asked Questions (FAQ)
Q: Is Photoshop hard for beginners to learn?
It has a steep initial learning curve, but beginners can start with basic retouching tools and build up gradually. The simplified Photoshop Elements version is a gentler starting point for home users.
Q: What is the difference between Photoshop and Illustrator?
Photoshop edits raster (pixel-based) images and is best for photo retouching and compositing, while Illustrator works with vector graphics and is best for logos and scalable designs.
Q: Which format should I use — JPEG, PNG, or TIFF?
Use JPEG for everyday photos and web sharing, PNG when you need a transparent background, and TIFF for high-quality, lossless print output.
Q: Do I need Photoshop CC, or are the mobile and simplified options enough?
Photoshop CC gives you the full feature set plus cloud storage. Photoshop Express (mobile) is fine for quick, basic edits and sharing, while Photoshop Elements suits hobbyists who want desktop power at a lower cost.
