I hadn't previously updated my Gimp as I was always to frightened of 'getting it wrong' (tech dummy), so I looked at http://gimpchat.com/viewtopic.php?f=7&t ... p&start=30
a post by Pocholo; "I have Windows 10 and the way I do it is, I uninstall the old version first. When you uninstall Gimp, the only thing that will uninstall will be program on your C drive Gimp 2. The directory on you personal Gimp folder your PC: C:\Users\Pocholo\AppData\Roaming\GIMP\2.10 will stay. DO NOT DELETE THIS FOLDER. You need this folder because you don't want to loose your preferences, (brushes, gradients, patterns, plugins, scripts...etc. Once you Install a new version, this new version will take over your Preferences and you will have everything you place in your preferences."
I followed these instructions and updated from 2.10.6 to 2.10.8, all plug-ins, brushes, patterns etc in place just dandy
NB; this for Windows users, i don't know about other OS.
A good idea to keep all the tips in one thread RJKD, one that for me makes things a little easier is the small icon at the extreme top right in the image below, when clicked the image is enlarged to fill the screen
I never noticed this before either. Thanks! The keyboard shortcut is CTRL+SHIFT+J, which is what I always use, btw.
When you save a .xcf, all the layers and paths you have made are kept. This is good if you have done a project that you might use again. Also you can play with the layers and alter the images any way you wish. You just go to File/Open. Choose your directory for saved files and press Open.
An .xcf file is like the whole project, as opposed to an individual image. One note about this is if you set up guides, the .xcf file will keep them intact, which can be really handy if you are working on different projects.
Remember, with Gimp there are very often more than one way to achieve things. "Where did my tool options go? grrrrr"
One thing related to this, in both single and multi-windowed modes, if you want to temporarily hide the dockable dialogs, just hit TAB, and it will toggle them on and off. When I first learned this, I had accidentally hit TAB, and suddenly everything disappeared. Don't reinstall GIMP like I did, just hit TAB to get them all back!
One useful tips for beginners is to always, always, always make a duplicate layer of what you are working on, and personally, I always work on the copy. If all goes well, you can simply remove the layer later, but it is better to have it than to make 100 small edits, and realize you can't undo something.
Another tip I find very useful for repetitive tasks, like applying the same filter or effect to multiple images or selections, is using two keyboard shortcuts. Previously, I had taken a screenshot, or written down the exact settings, then if I had 10 images, I would open the image, open the filter or setting, then manually enter the information. However, simply hitting CTRL+F will automatically apply the last effect and the last settings to the current image or selection. Likewise, if you hit CTRL+SHIFT+F, it will automatically open the last TOOL or filter or whatever you used, and let you manually adjust the settings as you desire. This has saved me a TON of time. Hope it helps!
One thing I realized I use constantly, even though I never really thought I would, is the quick reverting of the foreground/background area under the tools. By default, the foreground is black, and the background is white. Often, I use it to get new colors, and then I need black or white, and have to open it, then move the cursor to the top or bottom corner of the color picker window. Well, if you hit "D" on your keyboard, it automatically resets the BG and FG colors to B and W, and then you can also use the shortcuts CTRL+, or CTRL+. to automatically fill a selection with the FG and BG respectively. Use them all the time, hope it helps someone!
