Color Profiles and sRGB for DSLR Photos
Colours that look vivid on your camera can look dull after upload if profiles are mishandled. Camera JPEGs straight off the card can be many megabytes each, which is heavy for sharing or web use.
Recommended settings for DSLR photos
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 3000 px on the long edge |
| Quality | 85 |
| File size | 1000 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Color Profiles and sRGB
Most screens and browsers assume sRGB. Photos in wider profiles may shift when the profile is dropped during upload.
Browser-based compression outputs standard sRGB pixels, which is what DSLR photos expects. If colours change dramatically, export from your editor in sRGB before compressing.
