[5-21] “Economics of data: a photographer’s perspective”
Photographs for six years—I look back and see my camera accumulating data. Large amounts; D750 gets 24 megapixels (~25 mb/image), higher-ends capture 45 (~36mb).
The question about raw/jpeg is more what a person feels regarding speed:
JPEG (fast, compressed, web friendly) <--> RAW (large, flexible, unwieldy)
For my blog of practical images (receipts, readings, product reviews) I’d err to shoot in raw; the extra information is 99.99% superfluous, like carrying a textbook when only one chapter is needed.
The extra get chopped during export, anyways.
Many do not see this—there’s a tendency to believe more (raw) is better.
JPEGs:raw => 1:17 (size ratio)
With thousands of images imported each month, differences:
• Transfer/back-up speeds
• Need to export in low-resolution
• Previews take longer
• Slower to cull/navigate 😢
The question is more: “Then why ever use RAW?”
Simply, RAW is better if mistakes are made.
White balance is not baked in; highlights/shadows contain more data, more pliable (e.g. overexposed skin, underexposed shadows).
It makes sense to shoot long-term work with RAW.
It also makes sense for beginners, as storage is not a big problem; flexibility for mistakes helps.
Because a professional has an interest in speed, quantity is not preferable unless accompanied by quality. It is a mark of an experienced photographer who takes fewer but more interesting, useful, and variegated images.
