Welcome to the PG guide to photo doobering. This is not a complete guide, but rather a means to get started. If anything is mentioned that you already know, then move on to the next item.

A word of thanks goes to Frank Turk, aka centurion. Mr. Turk told PG about GIMP, and maintains a site called GIMPUNIVERSITY. PG/Chamblee54 and Mr. Turk disagree on a few issues. This does not affect the gratitude extended to Mr. Turk for his help in the field of PhotoDoobering.

You can use GIMP for a lot of things. Duh. PG is focused on what he calls photodoobering.(The pd word is seldom used in 2016) This involves cropping, adjusting color levels, adding color saturation, and the use of filters. The result is something resembling an impressionistic painting. If you want to use GIMP for other purposes,cool.
This is a PC based guide. If you use a Mac, then there is help available elsewhere.

1- Download GIMP. You can find it at This site also has an “owners manual” which describes how to use the different features.
If you have access to photoshop, then go for it. If not, then GIMP will have plenty of play things to keep you productive. GIMP is an open source program, which means FREE. If you want to make a donation then you will have the opportunity to do so.

2- There is no substitute for time. The amount of time you spend with your hands on the keyboard will have a direct result on the amount of pictures you produce.

3- Learn to work the keyboard. The keyboard is almost always faster than the mouse. It is like trucks and trains…trains are cheaper, but trucks go more places.
The GIMP has a feature which allows you to assign keyboard shortcuts. You can access this feature by going alt-f, k. Many of the tools already have keyboard shortcuts, which are shown in this window. You can assign other shortcuts to features that you use a lot. It is a good idea to keep a list of the shortcuts that you set up.
When a feature is described in this discussion, the keyboard shortcut will be in parentheses after it.

4- Cropping is a key part of the process. Many pictures will have parts that are not interesting. If you are going to post pictures to the internet, it is a good idea to keep these pictures at a 4:3 ratio. This means that horizontal is four units long while vertical is three units high. This is the ratio of most computer screens.
One of the select tools is Rectangle (R) . If you want your cropped selection to conform to the 4:3 ratio, go to the lower part of the tool box. Check Fixed, and choose Aspect Ratio. In the field below that, type in 4:3.( Another fun option is the “golden rectangle”. Set the numbers for 1612:1000)
To crop to the selection, hit Alt+I, C. On PG’s machine, this is W. Crop to selection is a very good use of the Keyboard Shortcut feature.

5-There are four tools for selecting parts of the image. These are Rectangle (R),Ellipse (E), Free Select (F), and Fuzzy Select (U). You can also select the entire image with Ctr+A. If you want to add to a selection, choose the proper tool, and hold down shift while making your selection. If you want to deselect a section, hold down the ctr button while using the appropriate tool. De select is a very handy feature.

6- If you make a mistake, you can undo your move using Ctr+Z. One of the good things about GIMP is that you can used Ctr+Z many, many times. PG has never hit the limit of how many times you can use this feature. (If you hit Ctr+Z one too many times, hit Ctr+Y to undo undo) (What would Jesus Undo?)

7- Do not change the original. Use “Export As” to save the changes you have made. Hit Ctr+Shift+E. Type in the name you want to use, followed by dot-extension. If you do not specify a format, the GIMP will save it as a .xcf. Numerous file formats are available, all of which have their pros and cons. PG likes to use the old reliable .jpg. PG also likes to include the number of the original in the name of the altered image.

8- Have fun. This is not rocket science or saving the planet. Take some pictures, open them with GIMP (or drag the icon into the toolbox), and start to play. Save your changes under another name. The GIMP instruction manual can be helpful, but is a bit on the technical/tmi side. Just spend time in front of the screen, and make pretty pictures.

UPDATE Here is a Tutorial, another Tutorial, and a Text Tutorial. Here is a tutorial about how to make Blackout Poetry.
