I have been a long time admirer of toned Black & White photographs. I recently read a book on this subject to see it I could use any staining techniques on digital prints (I see some tea and coffee staining experiment sin my near future). This book introduced me to the fact that some toners work from the highlights to the darks and some work from the darks to the highlights, so I thought to myself that this was a principle which I might be able to replicate in GIMP. I call it Quick N’ Dirty, as it is not an accurate representation of real wold toners, but it does produce an interesting image, in my humble opinion.
The original photo is of Cullahill castle in County laois, Ireland. It has had a quick “Auto Levels” adjustment but is otherwise unchanged. Persoanlly I didn’t much care for the colours which seemed oversaturated to my eye.
1. From the “Colors”menu select “Desaturate”. As you can see I have used the “Average” option here, but feel free to experiment.
2. From the “Colors” menu I next select “Curves”. On the “Value” setting I noted that the Histogram suggested slight underexposure, as such I dragged the top of the left slightly.
3. In order to simulate a green toner acting from the darks toward the hightlights I once again opened the “Curves” dialog. This time I selected the “Green Channel”. I mouseclicked in the centre of the curve (Straight line at this point) to add a n anchor point, I then dragged the bottom half of the curve upward to add green to the darker tones.
4. In order to simulate a blue toner acting from the highlight to the darks I again opened the “Curves” dialog and this time I select the “Blue Channel”. I again added an anchor point in the centre, but this time I want to drag the top half of the curve upward to add blue to the highlights (the sky in this case). Note that the curve is not as smooth as the one I used for green, this is because I noticed that the darker area in thetop left corner of the phot was not being affected, so I skewed the curve a little to counteract this.
5. I was going to call it a day at this point, when I asked myself “how would a more purple sky look?”. So back to the “Curves” dialog again, select the “Red Channel”, add a central anchor point and drag the upper portion of the curve upward to add a little red to the highlights. That’s about it, Sharpen and save it off. This effect may not be everyone’s cup of tea but I like the resulting image and it was fun to do.

OK, so she’s been with us a few weeks but I didn’t have a blog then. Here she is when she was a little wee thing. I thought that it was a little too soon after Lal’s death (our old dog) to be getting a new dog, but I saw her and fell in love. Mammy was a Rottweiler and nobody knows what daddy was, but she’s terribly cute. Personally by the look of her coat I think that daddy was a German shepard (Alsatian), that should stop people asking directions!, more of little Ms. Mischa to follow.
I’ve been asked about the name, not very Irish. Frankly I named her after Hannibal Lecter’s little sister. I was thinking of calling her Maebh, after Queen Maebh (Maeve in the English spelling, no “V” in old Irish). But this won out, thought to myself, could I picture her guarding castle Lecter when she grows up I and found that I could.
Loves ears they must be tasty.

The installation of the GIMP on a Windows system is very straight forward. However I do remember an issue which arose a few months ago when a friend of mine decided (was persuaded) to try the GIMP. He was becoming frustrated that every time he double clicked on an image file, the image would open in his old editing application and not in his brand spanking new GIMP installation, exactly the same thing happened with my first GIMP install.
This happens because unlike many other applications the GIMP does not steal file associations when you install it. However there are two simple ways around this.
Method 1: (Custom Install)
1. Double click on the Gimp Install file (get it at www.gimp.org) and the select Run. Select Next at the Welcome screen and Next again at the License Agreement screen.
2. At the Ready to Install screen select Customize
3. I usually leave the Installation Destination at the default and select Next. On the Select Components screen I normally leave it at the default again and select Next.
4. And here is where it gets interesting, on the Select File Associations screen scroll down and select all the file types you want to have associated with the GIMP. At the very least you will probably want to select .JPG and .TIFF but see for yourself as you may have other file types on your computer wish you would like to associate with the GIMP. When your done select Next”.
5. At the Select Start Menu Folder screen select Next and at the Select Additional Tasks screen select Next.
6. This bring you to the Ready to Install screen, select Install here and watch it run. JPG’s and any other file types you selected earlier will now open in the GIMP.
Method 2: (Set File Associations in Windows)
If you have already installed and GIMP you can either run the install again, this time selecting the Custom Install as outlined above or you can set the file associations in Windows, to do this.
1. Open Windows Explorer and from the Tools drop down menu select Folder Options…
2. Go to the File Types tab scroll down the list to. JPG and select Change then select “Gimp-2.6” and select OK. If “Gimp-2.6” is not listed select Browse to locate the file Gimp-2.6.exe manually, it is usually located in C:\Program Files\GIMP-2.0\bin\Gimp-2.6.exe
3. Repeat the last step to add any other file types you wish to associate with GIMP and select “Close” to finish. GIMP will now be the default editing application for the file types you selected.

Yes that’s right a weblog, I’m sure that this will come as an immense shock to any of you who know me. That said here’s the proof, one blog.
I decided to start this blog as my way to share my love of a few things, namely photography, dogs (cats are OK too) , snowboarding may even get a mention.
I am also hoping to put together a few photography or photo editing tutorials, which may be of benefit to someone at some stage. Just my way of giving something back to the hobby which has given so much to me. Don’t get me wrong I claim to be no expert but gosh darn it I’m trying.
Also, I Terence Moran hereby pledge to you unfortunate reader, that I will try to refrain from turning this blog into a rant. I do this for two reasons,
a.) if I start I might never stop (I have been accused of having principles)
b.) Some people think that you should never discuss religion or politics in the pub, however I personally feel that the pub is the only place worth discussing religion or politics. This second point takes care of at least some of the ranting possibilities.
So without further adieu, I bid you welcome.
