How may I help with torrents? Mind you, I’m no expert myself, but I can work on it …

“I know I could switch over my computer to Linux, but it would be interesting to see if they come out with a Windows port.”

No. This is sort of… um… I was going to say “political” )) The whole point of creating darktable for Johannes was to have such a tool on Linux. If I were you, I wouldn’t hold my breath for Windows version by dt’s principal developer. But if you want to port it to Windows, go ahead

@Norman

darktable is getting a year old one of these days and there is nothing really strange about Raw workflow tools emerging: UFRaw is really not sufficient when you are on deadlines. Been there.

Adobe and Apple have pushed great software for image processing and managing into the market. I have no doubt that the increased coverage in the magazines has nothing to do with the ads for Lightroom and Aperture.

So more people use RAW.

UFRaw is a very good tool but inherently ugly.

And then people are starting to program the next cool thing – and these are image managing suites. The good thing: it is all Open Source and so everybody can “steal” everybody else’s ideas. Let’s hope that we will see an arms race!

Good references are:

The definitive guide to HTML5 video is here: http://camendesign.com/code/video_for_everybody
although the code he uses as fallback is probably more complex than needed.

Basically only Firefox and Chrome can use Ogg Theora video now. Also some mobile devices, but not the iPhone.

The color stuff seems to bwork similar to the tools you have in Capture NX2 with the LCH-editor, in which you can affect a small range of the colours, if you wish. Make the greens brighter, the reds more satureted and so on.

PS: I think, no one really doubts your enthusiasm

For data backup, rsync is very efficient and it can be configured to the finest of degees. grsync gives a gui (but less functionality) if you are that way inclined …

Also test your harddisk, maybe with some tool like h2testw (runs fine under wine).

When RAM or a harddisk is failing you’re not only in danger of crashes but you might also corrupt your data (I’ve had quite some corrupted jpeg-images because of a malfunctionning harddisk.. but my system did not give me any warning ever, i just had growing number of images which had for example a brighter and a darker part)

Good luck with repairing your system! Take your time to make sure it does not destroy your work!

I’ll do a pure walkthrough throgh an image in the next show.

have you ever tested RawTherapee? I have not yet known UFRaw, thus the idea
Good luck, Jan

Great episode , i have really learned a lot today . Keep up the great work .
And , please , do some photo editing in future shows ( maybe new tricks ? ) . I really loved it when you showed us in the first episodes the basic stuff . Trying to imitate your work nearly two years ago was my first step in post processing , I kind of miss my german photography teacher . I miss Philippe too , he’s not around for quite some time .

Have a great week-end ahead of you .

Thank you for a really nice show, I really enjoyed it.
Thanks for the link to the ‘Rendering the print: the art of photography’ doc, it looks great too (haven’t read it yet, though).

Best

I hope that you dare to venture further down this alley. After all, these are very fundamental facts of digital photography and in the end, the best program (aka Gimp) can not help me when I choose to ignore them.

Regards, Stefan

PS: A very easy and clever alternative to hdr ala qtpfsgui (where you either need a doctorate in mathematics or a teacher like you) is enfuse from http://enblend.sourceforge.net/ Check it out!

As always love all of your camera theory thank you Rolf.

Please, if you would do this favour, continue in another Episode! I would love to hear more about the technical backgroud underlying the ‘arts’ part ! Finally somebody explaining the topic in a way, I can understand it. I don’t care if its correct in somewhat details; if I’m interested in, I can read them for myself. But breaking the important facts down to this level helps a great deal, to have the necessary background understanding the details.

In addition, pretty nice, seeing the possible future of our schools … Chalk on blackboard is always the right thing… I hate Overhead-Projections!

Regards, Axel

PS: And by the way, not wanting to imply anything, but I know a lot of people using PS, who would probably not be able to explain this matter in such an easy way…

Of course you are right in the second point, I was sloppy. The 9.81m/s² are “missing” in the reference system ISS (not observable) and are “present” (clonk) in the bus.

können wir nicht lieber alle z.b. mal ein portrait schicken, das >>> anständig <<< fotografiert wurde. (gutes licht, schöne person, schöner hintergrund, nicht zu viel bokeh, scharf.) dann wählen wir eines aus und dann kann jeder das post-produzieren und muss seine schritte notieren.

dieses bilder retten ist in meinen augen voll total sinnlos. (wer ständig bilder rettet, sollte lieber lernen, sich von bildern zu trennen und anständig zu fotografieren.)

I read it up. There are relativistic effects, quite some actually. That’s why I wrote “in the long run”. The decrease of altitude is not only because of friction due to some rogue atoms but also due to peripheral reduction of the orbit due to speed of movement (relative to Earth’s surface) and position in the gravitational field. Together with length contraction it sums up to almost a meter per month, which is quite a lot. Compared to more than a kilometer per year from drag it seems minuscule but it’s still amazing it’s in the same dimension and not just some micrometer or so.

> There are 9.8m/s² acceleration missing on the ISS.

Don’t worry, they aren’t missing, they’re still there. A little bit less, but the difference is not that noticeable. Thinking about it, it’s pretty clear, the station is hovering ~350km above the surface which is not much compared to the Earth’s radius of more than 6000km. The only difference in comparison to someone on the ground is, the station is moving. So while it’s falling to the ground is just moves enough to avoid crashing into Earth, resulting in a circular trajectory, also called orbit. It if would stop moving it wouldn’t fall much slower than someone down here. It just takes lower due to the long way. True weightlessness, aka 0g/m², only exists at the equilibrium, the zone between Earth and Moon where both gravitational fields sum up to zero. However, inside the station, with the hatches closed, you couldn’t tell the difference between both situations by any means so Einsteins law dictates we have to treat them as equal.

And then the same stuff happens as in a bus. The ISS increases its velocity, taking everything with it that is clamped down. The big Nikon wasn’t fixed to the ISS and stayed in the same position relative to the Earth. So the Nikon didn’t fly backwards, the ISS moved forward.

Let your camera or a bag dangle on a strap in a bs or train. With every acceleration your camera will swing backwards, every braking will push it forward. At least it looks this way because your system of reference is the bus, not the Earth.

Oh, BTW, on Earth don’t try this with your camera without holding the strap. There are 9.8m/s² acceleration missing on the ISS.

To an observer on the Earth the on-board clocks will appear to be running fractionally slower when compared to clocks on the Earth, and of course to the astronauts the Earth clocks will appear to be running faster by a very small amount.

Heres my quick attempt I thought it would be fun taking part in this fun competition thingy.

What I tried to do was split the photo so I had the girl reading the book clear as thats her reality in the middle I tried to do a silent hill feel where theres another world discontected from hers and then the top a dreamy world of her imagination… kind of like a comic thought bubble haha.

http://www.23hq.com/TeaKing/photo/5372946

My idea was to split the picture the foreground the girl reading being reality, the middle a kind of silent hill feel a world around us people dont see it just carries on with out us knowing then the top that is her dream the exciting thing thats going on in her book. Its a bit like a though bubble in a comic I suppose haha

my submission

I thought at this picture that she reads in an exciting thriller, which describes exactly a carnival parade in her imagination and created the images that appear around them.

Just two layers out of ufraw. First one with correct wb (cloudy), the other manual (3000K), 50% reduced saturation and -1/2EV. Normal wb one sharpened with usm, the other one blurred. Layer mask added to the blurred one with a radial gradient.

Something is wrong. Who can walk me through this stuff?

Last time I downloaded directly and then copied over torrent file and seeded alone. This time I cannot help out due to connection constraints.

Has anyone else run into this problem?
