Wideangle lenses for small sensor APS-C DSLRs

Good overview of wide angle lenses available for DSLRs. Expensive though, anyone want to buy the Canon 10-22 for me?

Canon 20D & RAW

Here’s a long thread which has almost convinced me that I should shoot RAW this weekend.
If I wanted to batch process I can probably do something like this:
for i in *.cr2
do
dcraw -c $i | ppmtojpeg > `basename $i .cr2`.jpg
done

RAW files are known to be much bigger. File sizes?
$ du -csh *
6.7M img_5881.cr2
24M img_5881.ppm
31M total

$ du -csh img_5879.jpg
4.0M img_5879.jpg
4.0M total

Shooting in RAW costs me almost 3MB of space per photo. I’m game to try it but the advantages will have to be absolutely amazing if I’m going to use it!

Linux Raw Image Management

I’ve steered clear of RAW photography for some time. Maybe it’s the extra few steps required to get a finished product, or the very large file size, or just that “it’s not jpeg!”
I changed the quality mode on my 20D to RAW this afternoon and was shocked when it told me that I could only take 79 shots! *gulp*
I fired off a shot, of an old Honda parked in front of my car and as I was in a hurry, forgot to do any more.
Later on I went searching and found a number of sites:

  • Raw Digital Photo Decoding in Linux – Dave Coffin’s dcraw seems to be the basic library that everyone else builds their GUI tools on. He went to the trouble of decoding the various RAW formats in existance.
  • Nikon D70 under Linux – plenty to read here, including a section on noise removal and links to a few GIMP noise removal plugins I must try out!
  • RawPhoto – the author says it’s beta quality code, but it works. I haven’t tried it yet however.
  • UFRaw – you can install this in Debian with apt-get install gimp-ufraw. I tried it. It works, now I have to read the user-manual to figure out what all those controls mean!

I’d post an example RAW photo but the only one I have is nothing to write home about so you’ll just have to wait in line like everyone else!

Naval Ships in Cork Harbour

Today myself, Ryan and AJ went down to see the various naval vessels docked in Cork Harbour.
Ryan has already posted some great photos and here’s some of mine here. The URL will change but I’ll update this post when it does!
I had a great time, the Germans got a great kick out of seeing a crazy photographer lying down on the quay taking snapshots of a coiled rope, but they did pose for a photo afterwards! It’s a pity my camera crashed minutes later and several of my shots were ruined :(

Sit-in at city shop

I went into town this morning and came across this group of protestors on Princes Street. I didn’t know it at the time, but they were employees of O’Donovans Butchers, a 105 year old company with a premises on the street. They had all been let go the previous day. The Evening Echo has more on their front page.
The workers were protesting because they were laid off almost a week early with very little compensation despite many years of service in some cases.

Dust on my Sensor! Must Clean It!

There’s dust on the sensor of my 20D. I need to remove it. Here’s a few bits I found.

  • Ken Rockwell has many tips, as usual
  • This review of IMS DSLRClean looked very promising until I found the exact same one here too! Is it a paid-for product placement?
  • Lots and lots of valuable information here.

Gulp! I hate the thought of wiping anything against my camera sensor!

Millennium Park loosens its photo rules

Looks like a win for photographers! Pro photographers who wanted to shoot in Millennium Park in Chicago had to have a city permit. That was only changed last month, so maybe I’m lucky that my 20D didn’t attract the attention of local security!
I would have loved to get a few shots of the Bean, but it’s being renovated and polished now, and was under a canopy. (via)
