Will Digital Images Last?

Only this morning I searched through my 35mm photos for photos from my holiday in Barcelona and I had to smile or grimace as I flicked through several years of photos – Paris, Spain, Chicago, Ireland.. All memories, good and bad. That’s fine for a once in a while trip down nostalgia lane but searching my digital images is easier.
Lance Ulanoff asks, Will Digital Images Last? in this PC Mag article. My 35mm snaps all fit in a small box but my digital archive already requires 3 DVDs to backup. What do we lose by not having the tactile feel of photos?

Sed one-liners

Cool! Several handy one-liners for use in Sed, the stream editor.

# double space a file
sed G

# double space a file which already has blank lines in it. Output file
# should contain no more than one blank line between lines of text.
sed ‘/^$/d;G’

# triple space a file
sed ‘G;G’

# undo double-spacing (assumes even-numbered lines are always blank)
sed ‘n;d’

The Missing Digital Photography Hacks [May. 11, 2004]

Here’s a couple of interesting digital camera hacks. The first one, an explanation of how the camera histogram works, is something I kept meaning to learn about for a while now!

What you want to be leery of is when the graph information bunches up on one side or another. A graph heavy to the left usually indicates underexposure with the image appearing dark (move exposure compensation to +1). If everything is scooted over to the right, that often indicates overexposure with blown highlights and washed out shadows and midtones (move exposure compensation to -1).

Later… There’s another 10 hacks on the book sample page!
