Grading Season

I have been very silent in mail, forum and video lately – it’s simply the grading season. Still standing in waist high piles of numbers, spread sheets and student output. Next week the worst is over.

EDIT Jan 23 – Well, one can dream…. I had a corrupt grade table to fight and some minor trouble with printers and paper. And then my PC power supply went dead Friday night. One Capacitor had a nice bulge on it’s head. Bought a new one, it stopped working after an hour and then of course the store was closed. Now I have a new one which seems to work fine. Tomorrow is completely filled up with work but on Wednesday I have a free afternoon for making a show.

Episode 174: Wilber in a Can

Download the Video! (21:45 43.3MB)

To get something festive to drink over the holidays I have ordered a special MTG-Beer from a brewery. It’s finest Pils in a can with Wilber on it! (Why a can and not a bottle – there is no “Make a Bottle Filter” in GIMP.)

In this episode I explore the Map to Object filter. It can render an image on a plane, a box, a sphere and a cylinder. The default dimensions of the cylinder are that of a beer can. Quite significant insight into the world of programmers. (BTW, the box preset is a cube, not a pizza box…..)

The image used in the show is stolen from Steve Czajka.

But before that is a look back onto the last show. Saul Goode shows a much easier way to generate patterns with the clipboard and I explain how I got the dots of different sizes in the blog image.

For all of you a happy holiday!

I hope to be back still in this year, so I’ll keep the new year wishes for later. As a distraction the 28c3 is coming up 10 minutes away from my home. I got no tickets but hope to get in there at night and watch some stream on the day.

Hand Craft and Digital Art – Custom Calligraphy for Meet the GIMP

Steve Czajka has made a custom calligraphy for this site – and he has documented the process in a well written tutorial and a video.

Have a look!

The banner on top is also (you may have guessed it ;-) ) from him. It will be there for the holidays. After New Year the rotation of your images will start again.

I wish you all a happy holiday and a good new year! (And there will be at least one more show in 2011…. :-) )

 

Episode 173: Lots of Dots

Download the Video! (14:10 26.9MB)

Meet the GIMP is on Youtube! Mike AKA Eppic has started this channel and is uploading all the old episodes. Thank You!

I need some dot patterns for a project with Moiré. And so this episode is deveted to building dot patterns out of a grid without grid lines. Misterious? Have a look at the video!

The video ends a bit abrupt. Cinelerra went on strike with the last part of the footage. So some stuff is left as an exercise for you!

In this show I explore the Color Balance tool to get the right mood into an image shot just after sunrise. These sliders push the colors around in the RGB color space. But how to push?

Then I compare the Curves and Levels tool and give both o them a shot at the image. Both results are fine on some parts of the image – just combine the two parts with a layer mask. An finally cloning out a disturbing sign at the edge of the canal.

After the recording I decided to do a crop of the image. You can see it on 23 and on flickr.

Pen Pal anyone? ;-)

I need (EDIT: Not now – schedule changes….) some one-time pen pals for my class – more later down in the post.

Fist about the next show. I put way too much time into trying to convert Nachbarnebenan’s Photivo/Gimp video into something that Cinelerra would eat. He has a new microphone, sound is well, tutorial well done – and the framerate changes all the time. No audio sync, wrong sync and at last a version with perfect sync that kills Cinelerra (and the whole system) 5 minutes into the video. I found that out after editing for quite a while – lots to do in the first minutes.

I started to record a show today but put too much on my plate GIMP wise – new try tomorrow.

Pen Pals!

I have to teach English in my class for some weeks. One lesson only per week, so no big deal. But I got the idea to have the kids answer some real letters from real persons – not only these fake ones out of the text book.

If you want to help me, send my class a short letter from your hometown, perhaps with an image or two in it. The kids are 13 to 14, learning English in their 4th year. Most come from migrant families (Turkish, Arab, Vietnamese), English is their third language. Some are starting to tackle French now too. So please don’t torture them with too high brow English, but they should be able to read more than Kindergarten level. And they have the Oxford dictionary….   ;-)

Most of them know basically only Berlin-Neukölln, TV and perhaps the hometown of their parents. Everyday stuff will be interesting for them, your street, your local attractions, where do the kids hang out….

You can mail your contribution as a text editor file (Libre Office can import a lot) or as a pdf to info@meetthegimp.org . I’ll print that for the kids. Or if you have still envelopes, stamps and so on, write to “Alfred-Nobel-Schule, Klasse 8d, Britzer Damm 164, 12347 Berlin, Germany”.

 

Of course you’ll get an answer from the kids!

Thank You!

Torrents will be back after solving the server problems.

While proofreading a new GIMP book as a “technical reviewer” I came across an interesting deviation of the presented recipe. Making a nightmarish effect.

It’s really easy, very flexible and you can learn a lot about some layer modes while playing around.

The original image is from my new Android phone, the quality is really good. So much progress in the last years. You can find it in the companion file and at Google+. ISO 1250, on a phone…..

The TOC by Kevin:

00:25 Welcome
01:30 The source image
02:24 Use the channel mixer to make a monochrome version of the image
04:05 Instead make the monochrome version using desaturate
04:40 Make blurred Hard Light and blurred Burn layers
07:48 Tidy up using the clone tool
08:45 The theory behind the burn layer mode
09:38 Make a test image to understand the burn layer mode
12:00 The theory behind Hard Light mode
14:00 Why were the layers blurred?
18:00 Remember to save your work
19:15 The End

Download Server Problems

Status

There are some severe but still unexplored problems at the download server. And not only there, it seems to be a larger problem at the uni. Marcin is on the hunt for people to put the blame on ;-) – and we all will have to wait.

Nightmare show is editied and ready for upload – when we have a server again.
