How many photos can 4gb hold？

Here’s a rough estimate based on common resolutions and file sizes.

1. JPEG Compression: If we assume an average file size of around 2MB per photo (a reasonable estimate for decent quality JPEG images from modern cameras), then a 4GB storage device can hold approximately 4,000MB / 2MB = 2,000 photos.
2. RAW Format: If shooting in RAW format, which typically results in larger file sizes (often 20MB to 50MB per photo or more depending on the camera), the number of photos will be significantly fewer. Assuming an average RAW file size of 30MB per photo, a 4GB storage device can hold approximately 4,000MB / 30MB ≈ 133 photos.

Again, these are rough estimates, and actual numbers may vary depending on various factors including camera settings, compression levels, and file formats.
