When you are out and about you may not always have your computer or laptop available with all of your required applications. GIMP Portable lets you you use the GIMP software on any PC without having to install it first.
Perhaps you are at work and you need to do a quick edit on an image. It is likely that you will not be allowed to install unauthorised software on work computers.
Keyboard shortcuts can be a great time saver when working within GIMP. Rather than navigating through the menu structure to find what you are looking for, if you learn some of the common shortcuts it will increase your productivity greatly.
Using GIMP for Windows you may have noticed that the toolbox is always on top. You maximise your image window and the toolbox stays on top obscuring part of your image. Some may argue that this give you access to the toolbar whenever you need it. Personally I find it annoying.
When working on large images I am often zoomed in to 400% and only viewing a small portion of the image. This makes it difficult to see any changes in context to the entire image. You could of course zoom in and out to see the overall effect of your changes to the image (the novelty of doing this will soon wear off).
The easy answer is to use the View > New View menu and create yourself a new view of the current image. You can set different parameters for your new view such as the Zoom.
This tutorial will take you through the process of removing image backgrounds step-by-step using the freely available gimp software. This tutorial assumes you are running the Windows version, but the concept applies equally to other versions of the gimp and other photo editing software such as Photoshop.
The assumption is that you have a basic understanding of how to use the gimp.
If you are interested in photography you will probably already know what a RAW image file is. If not, put simply it is an unprocessed image from your camera that represents the "as shot" state.
You can of course have your camera do the processing for you and apply things such as; white balance, sharpening and exposure. If you want to have greater creative control over your images, shoot in RAW rather than JPG and process the images on your computer rather than in the camera.
Using the GIMP it is an easy process to make seamless background images.
The background images on web pages are a good example of seamless images. They are generally small images which are tiled or displayed repeatedly by your web browser. This is very efficient mechanism as your web browser only downloads a single copy of the image.
Ever noticed that photos on some websites really has nice vibrant colours (no I didn't spell colours wrong, this is how we spell it Downunder - I digress) that seem to really catch your attention? Yet, your photo's are somewhat muted and dull in comparison.
With a very simple technique in the GIMP you will have your photos looking great in no time. Just one thing that I will say at this point is that you can make a good photo better but you can't make a poor photo good. So, before you start thinking I can fix all those duds, that's not what this tip is all about. This is about taking an already good image and improving it.
You would think that aligning text within the GIMP would be a simple task. Go to the "Text Tool" add your text and use the controls there to align "Left justified", "Right justified", "Centered" or "Filled". While that works fine but it may not be what you are looking for (you may not even notice any change if you only have a small amount of text.
Using this method will align the text within the boundaries of the new text layer that you added to the image. It won't align the text relative to the image.
I had a recent requirement to add multiple copies of the same image to a larger sized image for printing. Effectively I needed to tile the background of the larger image with my smaller image without any gaps. As there were many copies of the smaller image to be aligned I didn't really feel like trying to manually align each of the smaller images (I have better ways of spending my time).
