This is of course only a recipe, no set of rules and open for discussion and change. I have started to translate this into a Wiki. It's open for everybody who cares to create an account. text/html 2012-05-04T19:21:27+02:00 rolf http://wiki.meetthegimp.org/doku.php?id=compiling_2.7_under_linux_debian_esp&rev=1336152087&do=diff This was covered in #154 for Version 2.7. There is a more general and permanent solution here 2.9 is a development version. There is a big chance that it will not compile or run properly. If so, try the next day or week. Compiling under UBUNTU is described for 2.7 at blog.bloke.com and it is working like a charm. How much has to be changed for 2.9 is currently unnown. text/html 2012-05-03T08:42:52+02:00 nachbarnebenan http://wiki.meetthegimp.org/doku.php?id=more_tools_and_techniques&rev=1336027372&do=diff Multiple exposures of the same person or scene with just some detail(s) changes can be a lot of fun, as seen in episode 44. Doing this yourself is not difficult and a lot of fun if you follow a few hints: * Shooting The most important thing is to use a tripod — this is crucial. You may be able to get away with another kind of solid object to place your camera on, like a table indoors or your car if shooting outside, but a tripod is the easiest and most reliable solution. Second issue is to set… text/html 2012-01-01T00:05:56+02:00 nachbarnebenan http://wiki.meetthegimp.org/doku.php?id=keyboard_shortcuts&rev=1325372756&do=diff A lot of GIMPs functions are bound to keys or key combinations, so they are easier and faster to activate without having to use the mouse. As explained further down, the bindings can be changed, so these are the default values: * Undo (Ctrl+Z) restores the image state before the last editing step (“moving down the stack”) * Redo (Ctrl+Y) is the oposite to undo and restores the state after the last editing step (“moving up the stack”) text/html 2011-12-28T00:37:54+02:00 nachbarnebenan http://wiki.meetthegimp.org/doku.php?id=noise&rev=1325029074&do=diff Unless you shoot with a very expensive camera, there will always be sensor noise. It may or may not be noticeable but it's there. Several methods and techniques exist to counter it. Noise was covered in episode 36, 62 and 63. Noise removal uses additional image information to discern between actual image detail and noise. This method requires the most work but gives the best results. text/html 2011-12-26T00:29:39+02:00 nachbarnebenan http://wiki.meetthegimp.org/doku.php?id=bitdepth&rev=1324855779&do=diff Bit depth is the size of the datatype used to store the color information from one channel of a pixel. Normally this is uint8 which is 8bit and ranges from 0 to 255. Together with the most common color space RGBA and the three color channel being R(ed), G(reen) and B(lue) this gives a mximum of 16,777,216 (2563) different colors plus 256 different levels of opacity (A) for each and every pixel. So one pixel takes up 32bit all in all, usually stored in a uint32. text/html 2011-11-02T21:09:47+02:00 nachbarnebenan http://wiki.meetthegimp.org/doku.php?id=tools_of_the_trade&rev=1320264587&do=diff Several programs can accomplish different tasks at the same time, but it is sometimes advisable to use specialized software for each step in the workflow. The available programs can — roughly — be split into three major categories: * Management These are programs that download the photos from the camera or memory card and which you can use to tag, rate, sort and categorize images and export them to other programs or upload them to a photo hoster. Examples are digiKam and Shotwell Also, p… text/html 2011-11-02T20:56:11+02:00 nachbarnebenan http://wiki.meetthegimp.org/doku.php?id=motifs&rev=1320263771&do=diff Placement Normally, you'd consider that placing the most important part of the scene in the middle of the image would be the best choice. But in many cases this is not true. A seemingly slightly off-balanced image can be much more interesting and attracting more viewers than a perfectly balanced and centered one. The most used guidelines are the rule of thirds which some cameras can even show in the viewfinder, other examples of placement are the rule of fifths and the golden sectioning, an anc… text/html 2011-11-02T20:29:51+02:00 nachbarnebenan http://wiki.meetthegimp.org/doku.php?id=color_light_contrast&rev=1320262191&do=diff Contrast Contrast is the difference in brightness between neighboring pixels or regions. Together with color difference this holds the actual image information. First is an example of an image without contrast — it is filled with only one color/shade of grey. Second image has the maximum possible contrast at the edge in its middle, because the difference between the black and white regions cannot be larger. text/html 2010-11-03T19:41:01+02:00 http://wiki.meetthegimp.org/doku.php?image=gimpguide.odt&ns=&rev=1288809661&tab_details=history&mediado=diff&do=media
