I’ve been using Photoshop Elements 5 for some time now but there’s a few things it won’t do. I’m particularly interested in trying Tilt and Shift techniques but PE5 doesn’t seem to have the facilities to do this. I’ve always been interested in trying out GIMP but never spent any real time trying to make it work for me, so I’ve given up on it a few times. However now I’m going to make a concerted effort and I’m going to do by learning the features that I commonly use.
So to kick off I’ll be doing the following:
1. Install GIMP – easy enough, just follow the installer, I’ll not explain that
2. Get GIMP to read Canon RAW. I take all my pics in RAW these days but GIMP doesn’t recognise RAW “out the box”
3. Crop
4. Brightness/Contrast
5. Levels
6. Convert to Black & White
1. Installing GIMP
As mentioned I’m not covering installing GIMP, that’s easy enough to do. Instead I’ll tackle getting GIMP to read Canon RAW.
2. Canon RAW
It seems there’s a program/plugin called UFRaw that reads RAW files on behalf of GIMP. Follow the link and download the appropriate version (Windows for me) and install – it’s that easy. Now that I’ve got UFRaw installed I used it to open my pics, and it works fine.
3. Cropping
Simple crops are easy enough, just find the Crop button in your Toolbox and select the appropriate area.
However PE5 allows you to do photographic crops e.g. 6×4, 7×5 etc which is handy for getting images ready to print, and it turns out so does GIMP, again quite easily. I found out how from this link, but basically in the Toolbox, once you’ve selected the crop tool an option will appear for Fixed: Aspect ratio. In the box below you enter your desired aspect ratio e.g. 3:2 or 2:3 if you want portrait.
GIMP also provides a useful feature here known as guides, where you view your Crop with the “rule of thirds”.
4. Brightness/Contrast & 5. Levels
Quite easy this one as well. Select the ‘Colours’ menu at the top and then Brightness/Contrast. You can use simple sliders if you want but you also get the option to use Levels which have more flexibility. If you select Levels then you even get the option to do Curves (still got to learn them though!).
Obviously under this same menu you can adjust colour balance etc as well and you have access to some auto functions as well.
6. Convert to Black & White
There seems to be a few ways of doing this…
Desaturate
The first I found was to desaturate the image by going to the Colours Menu and select Desaturate. Here you have a choice of three options, Lightness, Luminsoity and Average, you can try each of them and see what happens if you have Preview checked.
Greyscale
To do get Greyscale go to the Image Menu, select Mode, then Greyscale
And there’s even more options listed here, too many for me to go through. Really I think you need to experiment with the options available, look at the link and decide what’s best for you.
Useful Resources
In writing this blog post I used the following resources:
Gimpguru.org – http://www.gimpguru.org/ – Used this resource most, got a lot of useful tutorials.
GIMP manual – http://docs.gimp.org/en/ – OK but I didn’t find it as useful as GIMPguru
More advice on plugins can be found here and some other GIMP tutorial stuff.
So I’ve quickly and easily found the tools I normally use in Photoshop, so no reason not be using GIMP. After a bit of practice with GIMP I’ll look at doing Tilt and Shift stuff.
