Vocab
Metadata: "data about data"
- provides information about the image file such as location, date taken, file size, and file extension, among other things
- primary purpose is to make sorting and organizing photos more efficient
PPI: number of pixels per inch of your image
- Affects print size and quality - can be heavily pixelated
- Defines the resolution of your image itself, with no bearing on the printer quality (DPI)
DPI: Dots per inch of your image
- Refers only to printer and ink used
- Generally, the higher the DPI (more ink dots/inch), the higher the overall quality of your image
Print v. Digital Photography
Digital Camera
Pros:
- No film - easier to carry
- Instant feedback - LCD screens mean you can see your photos immediately
- No prints - easier, safer storage; no risk of dusty or yellowed photos
- Flexibility - you can take more photos than print cameras because you don't have to worry about running out of film, and can delete them instantly if you don't like them
- Sharing - photos can be easily shared through phones or computers
- Editing - Poor lighting, focus, and colors can all be touched up in Photoshop or similar programs
Cons:
- Complexity - essentially mini computers and can be hard to handle
- Need for computer - don't bother if you just print your photos anyway
- Cost - High quality models can exceed $2000
- Battery life - Like any other electronic or batter operated item, you'll need rechargeable batteries or a lot of regular batteries
- Resolution - some detail can be lost, especially in black and white images
Print Camera
Pros:
- Cost - lower initial cost (i.e. the camera itself)
- More detail - in black and whites especially
- Resolution - most film is high res and forgiving of minor exposure or focus issues
- Heavier
- Storage - photos need to be physically stored, which can be expensive or just troublesome
- Editing - little potential to fix mistakes
- Developing - can't see the photos immediately; take time to develop
- Cost - film is a continuing cost, even if camera itself is cheaper than digital
