Mark Hancock was interviewed by a book author. Here’s his excellent interview: Collegiate PJs should know this.
The depth of his knowledge and experience blows me away time and time again. *phew*

Canon 10D, Linux and RAW Photography
2 Links from GalacticSlacker HQ:
Shoot right: exposure and dynamic range
Useful article on exposing for RAW. It’s based on expose right.
Apparently, it’s better to over-expose RAW images because that’s where all the sensitivity of digital sensors is. That said, I have read many times that one should underexpose by a 1/3 of a stop when shooting with a digital camera.
Must test later.
Linux: Auto-mounting USB camera memory
I have 2 cameras. One takes Flash cards, the other takes SD cards. If my Sony still worked, I’d also add memory sticks to that list.
I’ve got a routine, a workflow, for copying photos off camera media but it’s slightly more complicated with multiple memory types!
Kevin Lyda kindly mailed me a script he had for auto-mounting his camera and copying the files off. It uses the usb hotplug program to do that but I couldn’t get it to work with my card reader so I wrote the following script. Bits of it are from Kevin’s scipt, so thanks!
I insert my camera media, and run “copyfromcamera.sh” and it find the Flash card and copies all files off it into a directory with today’s date!
Make sure you have your media mount points setup in /etc/fstab. Here’s what mine looks like:
----------/etc/fstab----------
/dev/sdb1 /mnt/cfcard vfat users,noauto,rw,uid=1000 0 0
/dev/sdd1 /mnt/sdcard vfat users,noauto,rw,uid=1000 0 0
----------/etc/fstab----------
Copy and paste this into a file and save it to /usr/local/bin/copyfromcamera.sh and make it executable (chmod 755 /usr/local/bin/copyfromcamera.sh)
----------/usr/local/bin/copyfromcamera.sh----------
#!/bin/shexport YEAR=`date +%Y`
export TODAY=`date +%Y-%m-%d`
export DIR=/home/donncha/Photos/$YEAR/$TODAY/
mount /mnt/cfcard/ 2> /dev/null
if [ -d /mnt/cfcard/dcim/ ]; then
mkdir -p $DIR
find /mnt/cfcard/dcim -type f -print0 | xargs -0i mv -vi '{}' $DIR
umount /mnt/cfcard/
df -h
fi
mount /mnt/sdcard/ 2> /dev/null
if [ -d /mnt/sdcard/dcim/ ]; then
mkdir -p $DIR
find /mnt/sdcard/dcim -type f -print0 | xargs -0i mv -vi '{}' $DIR
umount /mnt/sdcard/
df -h
fi
----------/usr/local/bin/copyfromcamera.sh----------
The Digital Journalist – July 2005
A bit late this month, but Dirck Halstead the July 2005 edition The Digital Journalist is out.
It has plenty to read, including a good article on the emergence of “citizen-journalists” armed with camera phones.
Photojournalism history was made last week. For the first time, both The New York Times and the Washington Post ran photos on their front pages made by citizen-journalists with camera phones.
As I was snapping the sunset in Kinsale last night with my cumbersome 20D, swapping lenses, and swearing when I realised I had left my second memory card at home, someone else got out of their car, hopped up on the ditch and pointed their phone to the west. Somehow I can’t imagine it matched my 300mm zoom, but the future is now!
Processing a Digital Photo
Here’s the digital workflow of one photographer. The steps he describes can be followed in the GIMP too.
Despite earlier reservations, I’m still shooting in RAW format and it’s been useful on occasion. I find it useful to slide the shadows and gamma settings around and then hitting “auto-adjust”.
I always have to use the Auto-Levels tool afterwards to fix the colours but the RAW converter does give me some extra control.
I can see I’ll need to make backups a lot more regularly however. DVD is way too small.
All about fstops, shutters and iso settings
This metafilter post is a mine of information about basic camera terminology. I shoot almost exclusively in Aperture Priority mode, or even in Manual mode now.
This post will help explain how those numbers affect your photos. (via)
The Sensor Did It!
Good article giving an overview of DSLR sensor and lens issues such as the multiplier effect and why you can’t get a real super-wide lens for DSLRs.
The Digital Shopping Dilemma
You bought a new camera? Oh goody! Oh look, there’s a newer version with shiny new features! Doh!
Get over it and take great photos! Read more in this essay by Mike Johnston.
