Understanding 16GB Storage for Photography
File Format Impact on Storage Space
The choice between JPEG and RAW dramatically affects your digital photo storage requirements:
JPEG Characteristics:
- Compressed format with smaller file sizes
- Typical range: 3-10MB per photo
- Perfect for social sharing and quick workflows
- Limited post-processing flexibility
RAW File Details:
- Uncompressed format preserving maximum sensor data
- Average size: 25-50MB per photo

- Industry standard for serious photographers
When comparing RAW vs JPEG storage space, RAW files consume 3-5 times more capacity but provide unmatched editing flexibility.
Memory Card Storage Calculator Formula
Use this memory card storage calculator method:
Available Storage ÷ Average File Size = Total Photos
For a 16GB card (approximately 15,000MB usable):
- 15,000MB ÷ 5MB (JPEG) = 3,000 photos
- 15,000MB ÷ 30MB (RAW) = 500 photos
