The remains of a boat lie in the water by Dunboy Castle in Co Cork, Ireland. We were there last March, only days before 3 young men were killed when their car went into the water.
As you may know, I’m in Colorado along with most of Automattic. You can check out photos taken by me and my colleagues. It’s a beautiful area, but the thin air at such a high altitude is playing havoc with my body: breathlessness, a racing heart while lying down, sinuses out of whack, the after effects of 3 drinks feels like a heavy night of boozing.
Budget Day today in Ireland. If I don’t catch the RTE coverage of it live I’ll watch Twitter and check the headlines after.

Chains on a quayside in Schull, near where yesterday’s shot was taken, I think.
I’m in Colorado, at 9,00ft. The air is noticeably thinner here. Won’t be any running about or physical exercise for a few days!

Fishing tackle in Co Cork somewhere. Can’t remember where now! Love the texture of this sort of equipment, especially in black and white.

Carvery Lunch, the fast food of “proper food” IMO. Many will be going to pubs today for their Sunday lunch and it’ll be carvery on offer. Nothing wrong with it of course, but some people are snobs about eating out and want food delivered to their table. Considering the price of carvery food, I can see their point. It’s generally the same price as food in a restaurant, so why not eat somewhere else?

A small ferry casts off and heads out of Bantry Harbour with lots of hunting dogs and their owners. This was last February and I watched with interest wondering where they were going.
More QE2 photos to come, when I have time to work on them!

The curves tool is a very basic tool that can be used to improve photos with a few clicks of the mouse. It is used to change the brightness and contrast of an image. It can also modify the separate Red, Green and Blue channels of an image too. The Curves Tool has a histogram to represent the shadow, midtone and highlight detail in the image. In the GIMP, you access it by right clicking on an image and go to Colors->Curves.
This is the second article in my GIMP for Photographers series, but as usual, all of this applies to Photoshop, or any other image application with a Curves Tool. The first tutorial was on The Levels Tool, and worth a read if you missed it!
Here’s an image I shot at the Lord Mayor’s Picnic in Fitzgerald’s Park a few months ago, and the Curve Tool below it. Notice the histogram? The photo is fairly well exposed, but some highlights are “clipped”, as the histogram hits right hand side without sloping off.

It’s easy to brighten an image. Just drag points on the line up.


Now, let’s darken the image by dragging points down.


A classic use of the Curves Tool is to increase contrast in an image. You do this by darkening the shadows, and brightening the highlights. The curve looks sort of like an “S” when you do this. Don’t go overboard on this though, because it’s easy to lose detail in either direction.


If for some reason your image has too much contrast, a quick inverted S curve will solve that problem,


You can select any of the Red, Green and Blue channels and do strange things to your photos. Here’s what happens when you play with the Red Channel.


And here’s what happens when you change multiple colour channels in different ways.

After you have opened the Curves Tool, click anywhere in the image. Notice how a vertical line goes up and down the histogram/line? That vertical line is the colour of the pixel where you clicked. That can be useful if you’re trying to modify a particular part of a photo. This is what you get when you click on the black coat on the left of the image above.

Eddie Rocket’s in Blackpool, Cork. I haven’t eaten here. The last time I did was in Galway at a Linux thing, probably in the late 90’s when all I remember was that it was overpriced. Still the same?
