Profile that Thing

I recently purchased the Coloreyes Display Pro app with a spectrometer module. This attached to your computer display and then software will show specific color patches for the spectrometer to read. As your monitor needs a profile to interpret the colors of a given color space, you normaly have to assume that it's taking the right decision and shows you what he wants to show you. Such a system can help in that it adepts the profile of you specific monitor under your specific working conditions and creates a custom profile for your operating system. So basically, after profiling, you see what the OS thinks he's showing you. This is crucial for photography, especially printing, as the systems conversion engine assumes that your monitor is configured correctly. This is why you often get a slight tonal variety in your prints, and can be quite an annoyance. Profiling my MacBook showed practically and ideal profile, whereas my old CRTs gave catastrophic results before profiling. I guess sooner or later I'll have to switch the screens anyway, but most importantly I now see what I got!

From Camera To Print - Fine Art Printing Tutorial


If you're into photography and ever wanted to do you own prints, you probably ended up with your fair deal of deception. Fading colors, lack of sharpness etc are rather common among printing amateurs and to adress this, Michael Reichmann from The Luminous Landscape along with Jeff Schewe created a 6h video tutorial covering anything related to optimizing your prints that you can imagine. It costs 35$ and worth every cent of it! 5$ will go to the newly created Endowment fund to support photographers with grants. I can warmly recommend this tutorial, eventhough I've yet only seen the first 2 videos!

Panoramic View of Luxembourg City

Panoramic View of Luxembourg city, Pont Grande-Duchesse Charlotte, Kirchberg, Pfaffental, Grund, Findel and Cents

I love panoramic stiching. But this one really was a pain to realize. Even when ignoring the fact under which safety precautions I took them... Because doing a panoramic stitch with 40x 12 MP images shot in RAW means calculating and lots of temporary space. Although I praised the CS3 pnaoramic stiching capacities in a former post, when coming to a monster such as this one, PS will fail (if you do not happen to have some 8 GB of RAM and 2 Quadro cores). So I moved to PTGui, which is a very nice alternative, if you want more user interaction. The app will set a number of cross-referenced control points that the user can then adjust. Well you do have a million of other options which I will not go into, let it just been said that after hours of control-point setting the calculations could finally begin yesterday evening. After 20 s the first Warning: Will require 105 GB of temporary space... Lucky I have enough external HDDs... It took some hours to produce the final 17'500x4062 px monster (that's 71 mega pixels for all you humans). Sweet, and that in 16 Bit, say hello to a one GB big image. Well, as you can imagine, I won't put it online in the original size...

Photoshop CS3 and Panorama stitching

In my opinion, there has been less fuss about the latest addition to Adobe's family than usual. That being said, I find nevertheless that Photoshop CS3 has some very interesting improvements, one of them certainly being the panoramic stitching capabilities (not to mention the speen etc...). This function, to be found under File-Automate-Photomerge, is around since the last couple of Ps, but since now did never a great job in convincing me to rely on the majorly automated stitching process. I always loved working with PanaVue Image Assembler, even though in could be a real pain in the arse, especially when working of multi-line images (stitching a 5x8 or so panorama). Well I did not really expect the CS3 version to have any major updates, but I was wrong. Its engine just feeds on the images you give it, and outputs you a near perfect result, merging the pictures with layer masks for easy editing. And this even with 16 Bit files! Yummy! More RAM please!

BTW, this ones a 140 MPixel image in 16Bit, please forgive me for uploading a resized version...
