Discussion about raw photography. Notes at the bottom of this post
Competition winners:
- People’s choice award to Marg T for Yarck
- On-the-night award to Fiona Nika and Mike (the split rock image)
Next meeting: A WEEK EARLIER DUE TO SCHOOL HOLIDAYS: 24 JUNE. Kick start for a Lightroom beginner. Adam/Mike or others to run through the Lightroom basics on Catherine’s PC. (Mike will have a backup machine)
Future discussion topics: Please speak up if there is something you would like to learn about or discuss. I am happy to research anything to do with photography, or delegate!
Discussion around cloud storage. Crashplan and Amazon Glacier discussed
RAW
Actually “raw”
What is a RAW file?
- Not an image file
- Uncompressed. Larger than JPEG. Eg 22.9MB vs 4.4MB
- Lossless data from the sensor
- Higher dynamic range
- Not suitable for printing directly from the camera or without post processing.
- Can adjust white balance in post processing
In comparison a JPEG is…
- Standard
- Faster
- Compressed. Options – size and detail.
- Lower in dynamic range
- Able to be printed
- Able to be edited
- More compatible with other packages & applications
- Sharper. (Cannot undo/change)
Shooting in JPG
- Image is compressed. Some information lost
- 8 bit > 256 shades red, green and blue > 16 million
Shooting in RAW
- Needs DSLR
- Computer does the processing
- Select white balance
- 12+ bit > 68+ billion colours
Why
- Because you can?!
- You control the conversion, not the camera
- The SW for post processing offers a lot of tools and controls available.
- Easier to recover from mistakes / non ideal situations. Eg pulling details out of under-exposed images
- ‘Edits’ are non- destructive. Only a bunch of instructions for processing
What do you need?
- DSLR
- Software
Considerations
- Needs more storage. Memory card and hard disk. Impact on backups.
- Needs SW for post processing. Lightroom, Aperture, Photoshop (Camera Raw). Looks like Picassa can do for free, but I haven’t heard of anyone seriously using it.
Other discussion topics
- Shoot to the right. Do people do it?
- White balance - any definitive list, or whatever looks good?
- Sharpening techniques. Hard and fast rules or whatever looks good?
- People worry about colour space? (for personal use? For professional?)
- RAW is proprietary. Some people convert to TIFF or DNG
