Long time no show – but this project is not dead. For the fresh start a new design for the intro is needed. And a new design needs new colours.

I used the Colorschemedesigner to create a palette of colours fitting the “Original MTG Orange” from the logo. Clever algorithms use old artists knowledge about colour combinations. This site even exports a GIMP palette file which is then imported into GIMP.

For the lettering I wanted some fresh fonts and found them at the League of Movable Type.

Episode 185: The 52.02 €rror – Printing with Profiles

Download the Video! (36:50 73.4MB)
Download the companion file with my printer profiles! (3.9MB)

I gave myself a real photo printer for the 5th anniversary of “Meet the GIMP!” and have now my work-flow ready to print in the “right” colors. One reason I shied away from printing for years were the costs. Original Printer Ink is one of the most costly fluids that are traded commercially (1544.54€/l (1) is not the highest price you can pay) and good paper is expensive. But now I have found a combination of a good printer, which is subsidized by small and expensive ink tanks and a good second party ink for 1/6 of the price. The ink is pigment based and so doesn’t bleach out in the light so fast as dye inks. Added to that two good but cheap papers for making beginners mistakes.

Of course the colors are off when I print with the usual TurboPrint driver. TurboPrint knows neither ink nor papers. So I needed two printer profiles – one of them was already payed for with the ink starter set. Well, I had to buy two more profiles because I had made a big mistake while printing the test sheets. Take care to switch off all color correction while printing calibration charts.

With the right ICC profiles GIMP can give you a Soft Proof of the image that is going to be printed. The look of the printed image is simulated on the screen and you can adapt the image to get your best result.
All you need to know (and much more) about calibration and the different “intents” is at Cambridge in Colour and at the Idea Machine.

(1) It’s even worse than I said in the video. The ink cartridge holds 11ml and costs 16.99€ Epson list price. That’s 1544.54 per liter. farbenwerk C7 runs up to 275€/l in the set and 230€/l for the ink only. Quite a difference.

Episode 184: Scraping the Web!

Download the Video! (14:04 28.0MB)
I found a new feature in GIMP, no idea how long it has been hidden in the files menue. One can import a whole web page in one image! Better than a screen shot, because you don’t need to scroll down. The web site of the GIMP Magazine results in an image of 1024×16037 pixels, quite an extreme portrait format. It doesn’t work with all sites and sometimes results in render errors. But it is a nice tool.

The GIMP Magazine will have it’s launch in some days on September 5, you should know this by now. ;-)

I helped a bit publishing a book, working as a Technical Reviewer. I got the drafts of all the chapters as a Libre Office File and worked through it, filling it up with nasty comments. So I can claim that I have read every word in Michael J. Hammel’s book “Artist’s Guide to GIMP, 2nd Edition” that I have on the lab bench in the second part of the video.
It is not a text book but a collection of small and medium sized projects. You learn by doing stuff.
Of course I am a little bit biased, got some money, fun and a box of books, but I would also have recommended the first edition of this book. And the second one is better!

The TOC

Not really needed here – the show starts with creating an image from a web site and switches over to the book review at 7:40. Nothing more in it.

Episode 182: A Special Day

5 Years of Meet the GIMP!Download the Video! (30:37 61.1MB)
Download the companion file! (65.5MB)
It’s a special day today, five years ago I rolled out the very first episode of “Meet the GIMP!”. And now it is #182, that’s 0.7 episodes per week. ;-) Update: An error corrected below and the comments are working again!

But the show starts with an other anniversary. Twenty years ago these days Tim Berners-Lee (still without a “Sir” in front of his name) published the first photo on the World Wide Web. Up to then it had spent it’s first year or so text only. The users and servers were somehow connected to the CERN particle collider near Geneva. What’s better to put on an image in a nerdy environment than a band? An all female High Energy Rock Band, Les Horribles Cernettes, of course. So a quick and dirty Photoshop (Version 1) hack (yes, web sites were that ugly once…) intended as a base for an in house CD publication found it’s way to the computer of Berners-Lee and history was on it’s way. There seems to be quite a dispute about this just now. Why can’t people keep proper records when they are making history? ;-)

 

Some epsiodes of Meet the GIMP! have found their way into an education program of the Indian Institute of Technology in Mumbai (Bombay). They dub them with Indian English and publish them on their server. The project Spoken Tutorial is a great way to reach out and broaden education. And of course I am proud that my material is used that way.

I love the Greyscale Icon Theme by Eckhard M. Jäger of the “Linux for Designers” blog. Keeping the active icon in color is a nice touch.

Ramon Miranda has updated his GIMP Paint Studio. This is a collection of brushes, patterns, gradients and more, bound together by presets and dynamic settings for tablet users. (If you don’t have a tablet, get one now!)

The GIMP Magazine is taking up steam. I have seen the drafts, they are nearly complete and get better all the time. Expect the first issue in early September.

And finally I process an image of a small part of the steam engine 01 1066, which I found in the Hamburg Main Station. The processing is nothing spectacular, just cropping, curves, a bit of burning and dodging. But this time I am printing the image on my brand new printer – an Epson 1500W. An Episode about printing is coming up, just now I am just playing around.

UPDATE I made a blunder here and switched the terms dodging and burning – I got the reminder of proper dark room culture from Saul Goode in the forum.

Burning is letting more light from the enlarger onto the paper (as I told in the show) but as it is a negative projected on light sensitive paper  the image gets darker. So I burned the lower right edge of the image.

Dodging is keeping light away from the paper and so making that part lighter, no light at all would result in unchanged white. I dodged the rust on the fitting in the center of the image.

And here comes the twist. A “burned out sky” is white on the final image because it has been “burned out” the negative, resulting in solid black there. I haven’t been in the dark room lab for decades, perhaps I’ll try it again after the printing fever has gone old. ;-) (BTW, my new pigment ink and refillable replacement cartridges arrived today…. )

A very good demonstration of burning and dodging is done in the film War Photographer about James Nachtwey. Worth watching, even without interest in dark room technique.

A big thank you to all of you for the support in these five years!

Episode 181: 2.8, 2.9 and Counting!

Download the Video! (24:08 48.1MB)
A week of news: GIMP 2.8 is out, we have again a modern stable version of GIMP. Gratulation to the developers, this was good and hard work. But instead of relaxing a bit they threw at the same moment Version 2.9 into the world. High bit depth, not only the 16 bits everybody wanted, 32 bits integer and floating point modes are suddenly available. But be aware, this is a field of bugs and crashes, don’t expect any productive results yet.

In a first look at 2.8 I show the shiny new brushes, explain how to use the new sliders and the tagging system for brushes, gradients and patterns. For the lazy I add a bit of calculations in input fields.

Then nachbarnebenan takes you for a tour through 2.9, presenting the lossless operation of the layer stack and other stuff. But again, this is not for the faint at heart. If you want to compile 2.9 on Debian, here is a How To in our Wiki. (The link address says still 2.7, but it is 2.9….)

Episode 180: Not for Grown Ups!

Download the Video! (23:24 46.4MB)

Tuxpaint is a painting software for kids between 3 and 100+. Well, the targeted audience ends at an age of 12, but it is still fun to use when you are older. Tuxpaint is available for Linux, Mac OS X and all Windows flavours. Of course it is under the GPL and so free to get and to be shared. The ease of use beats everything I have seen in the professional educational market and I am considering to get it into my school.

The user interface and availability of tools in Tuxpaint can be configured to adapt to the skill level of the user and the level of annoyance the environment is willing to tolerate. There are nice sound effects, but how often can you stand

“QUAAAAAAAKQUAAAAAAAKQUAAAAAAAK DUCK”?

Also printing can be disabled because space on the fridge and ink cartridges have limits. The configuration is done with a separate program which can be kept outside of the reach of the little end-user.

The show starts and ends with some information about the upcoming GIMP Magazine. I am somehow involved in the team now but I promise to keep my priorities on this project here.

And then there is an invasion of goats int GIMP and 16 bits and more are in reach.

Episode 179: Corners and Edges

Download the Video! (9:03 18.0MB)
I am on my way to a class trip an so you get only a short episode about the corners and edges around the canvas. There is a menu button, a zoom mode button, a navigator and the quick mask for selections. And of course there are the rulers with the guides and control points to pull out.

All this after a quick update on the histogram from the last show.

Episode 178: Lurking in the Shadow

You are in for a night-time trip to one of the most secret places on the earth – until 23 years ago. The former Stasi headquarter is only 2 subway stations east of my home and I quite like the morbid, spooky atmosphere there. It’s a really huge areal, lots of office space and other buildings. Some of them are used as a museum and as the archive for all the Stasi files. Others are rented out or are simply empty.
My image missed some details in the shadows. I used a modified “burn with a layer in Overlay Mode” technique to get a bit of light into them. Instead of painting on the layer I used the L-part of the LAB colour model. I got the idea for this from the Darktable Blog.

UPDATE Mar 18: There is a nice way to use the histogram with selections. Select the dark region and look at the histogram – it shows only the data from the selection. The histogram tool is “selection-sensitive”.

Thanks to GIMPel for the tip.

Episode 177: Take 2 and GIMP!

Nachbarnebenan continues his tutorial from the last episode. He isolated his model from the a bit to vivid background by making two images from his RAW file. One is crisp and colourful – best for the model. The other one is soft and a bit dull – this tones the background down.
In this episode he combines them to one image with a layer mask.

Did you know that there is a filter in GIMP to emulate the look of an image for colour blind people? Nachbarnebenan shows how to use it. It’s no so important for photography – but think of all the graphics work done with GIMP. By using this filter you can make a difference in accessibility

If you want to get into programming plugins for GIMP in Python – here is the link to this great HD video from Gimpusers.com.

And for the next episode you’ll need a Trench coat and dark glasses – we’ll enter the Stasi headquaters at night.

Sorry, no TOC up to now, but at around 15:30 is the great segment about GIMP and colour blindness.

Episode 176: Double Photivo

It’s time for a guest again. Nachbarnebenan shows how to process a RAW image in the current (well, it was November…) version of Photivo. Photivo has a very different approach to image processing from GIMP and others. It’s more stacking up and tweaking of algorithms instead of making a series of changes one after the other. Fully non destructive and very powerful.

To isolate the model from the a bit to vivid background Nachbarnebenan produces two images from his RAW file. One is crisp and colourful – best for the model. The other one is soft and a bit dull – this tones the background down.
In the next episode he will show how to combine these two images in GIMP into one.

I am still looking for “Bad Good Images” from Phones and other not so good cameras!
