Understanding Image File Formats

The video explains various image file formats, including JPEG, PNG, GIF, TIFF, PSD, RAW, and vector formats like AI, CDR, SVG, EPS, and PDF. It covers key concepts such as raster vs vector graphics, lossy and lossless compression, color spaces, bit depth, and alpha channels. The video also shares a personal experience with file formats and concludes with advice on choosing the right format for different applications.

What is the primary difference between raster and vector graphics?

• Raster graphics store images as a grid of pixels.

• Raster graphics are scalable without loss of quality.

• Vector graphics are made up of pixels.

• Vector graphics cannot be enlarged without losing quality.

Which type of compression is used by JPEG files?

• Lossless compression

• Run-length encoding

• Lossy compression

• No compression

What is a key feature of PNG files that JPEG files lack?

• Support for CMYK color space

• Lossy compression

• Alpha channel for transparency

• Higher bit depth

Which format is known for supporting animations?

• JPEG

• PNG

• GIF

• TIFF

What is a significant advantage of TIFF files?

• They support both lossy and lossless compression.

• They are limited to 8-bit color.

• They are always compressed.

• They cannot include an alpha channel.

Which format is the native file format for Adobe Photoshop?

• PSD

• TIFF

• JPEG

• RAW

What is a characteristic of RAW files?

• They are limited to 8-bit color.

• They preserve all sensor data.

• They discard some image data.

• They are always compressed.

Which vector format is widely used and supported by modern browsers?

• AI

• EPS

• CDR

• SVG

What is a common use for PDF files in professional settings?

• Capturing photographs

• Delivering final artwork

• Editing vector graphics

• Storing animations

What personal experience did the narrator share about file formats?

• Switching to PNG for its alpha channel

• Using JPEG for 3D modeling textures

• Choosing TIFF for web graphics

• Preferring GIF for animations
