Practice Assignment

1. Imagine that you’re working on a marketing poster in Adobe Photoshop, and your client requests a version that can be quickly shared on social media with a square crop and optimized file size. How should you prepare the image to meet their request while maintaining quality?

  • Resize the original PSD to a smaller resolution and save it as a TIFF file.
  • Use the Save As option to directly save the PSD as a social media -ready format.
  • Crop the image to a square aspect ratio, adjust resolution for web use, and export as a JPEG. ✅
  • Merge all layers, apply a blending mode, and save the file as a PNG.

Explanation:

  • Social media platforms typically prefer square images (e.g., 1080×1080 px for Instagram).
  • JPEG is a web-optimized format that balances quality and file size.
  • Adjusting the resolution (usually 72 PPI for web) ensures fast loading while maintaining visual quality.

2. A colleague asks you to blend two photos in a composite image to create a gradual, seamless transition. What tools should you use?

  • Flatten the image and adjust the opacity of one layer.
  • The Clone Stamp tool to smooth the edges.
  • Layer masks and the Gradient tool to create a smooth, gradual blend between the photos. ✅
  • The Quick Selection tool to blend the images.

Explanation:

  • Layer masks allow for non-destructive editing, meaning you can hide or reveal parts of a layer without erasing data.
  • The Gradient tool applied to a layer mask creates a soft, gradual transition from one image to another — perfect for blending.

3. You’re refining a selection around a complex subject in Photoshop. Which tool offers the most precise way to adjust the edges?

  • Quick Selection Tool
  • Eraser Tool
  • Select and Mask ✅
  • Magic Wand Tool

Explanation:

  • The Select and Mask workspace provides powerful tools to refine complex selections — especially useful for hair, fur, or intricate edges.
  • It includes options like edge detection, feathering, contrast, and shift edge to fine-tune the selection.
