Sorry – no mobile version yet!

A short one this time – I upgraded to Karmic Koala and did a clean install with new partitions and EXT4 file system. And now I am getting the important stuff back on the disk and leave the cruft out. This meant that a lot of the files needed for a proper podcast are still on the external disks.

I take a look a the new Folio by Jeff Curto at Lenswork – because it’s an example of printing an image on paper with a different aspect ratio, the images are really good and Jeff is a friend and I hope he sells a lot of them.  Jeff does two podcasts in the Photocast Network, Camera Position and The History of Photography. The last is the only podcast where I have experienced a coffee break.

I use an image from “wbool63″ from the forum to make some nice frames with G’MIC, the Swiss Knife plugin from France.

And I have done….

No blackboard this time – and no mobile version  yet. The upgrade broke the toolchain, I have to compile ffmpeg to get it running again. Software patents are really …….

This weeks show starts with some additional talk about tablets. After Episode 101 there still was the question if a Wacom Bamboo tablet is “good enough”. Matthias visited me with his tablet and we sat in a street café and compared. (Sorry, the sound in this segment is not very good and out of sync.) The Bamboo is as good as the Intuos if you don’t need diffenrent pens. I would buy one. (Too bad that I don’t get money from W….)

Then I follow a comment from Steinar and explore the Device Status dialogue. It gives you all information you need about your row of input devices. Even if they are plugged in too late.

In the image I tackled last week were some really big damages. And I tried to fix them with the Resynthesis plugin and G’MIC. Both did well with small defects and considerably good with the big ones. They were only at loss where knowledge about the world was needed – like in the back of the chair. We know that the wood goes on – the computer does not. Perhaps the result would have been better with the first plugin if I had followed Tobias’ tip thoroughly.

UPDATE: If you call the Resynthesis plugin via Filters/Enhance/Smart remove selection you get a much better result. See in the image on the right.

Both plugins are not easy to use and need ore time to explore than I was motivated to invest. I found no way to “automagically” select the damaged parts of the image. Perhaps a scan in full colour mode would have been better. There may be a colour difference between dirt and image that can be exploited for a selection. So, scan in RGB!

There is a an other plugin perhaps usable for such work. It’s the Wavelet decomposer. I’ll try that in a later show.

At the end of the show I tell you a bit more about this young man, show Norman’s version of the reconstructed image and propose a different approach with an oval “matte”, like it must have been in the original.
