In my first article on simulating tilt-shift miniature faking with the GIMP I linked to instructions from Gimparoo!. Firstly, these instructions are no longer completely correct on the latest version of the GIMP because some of the menu sequences used have changed. Secondly, I've been looking at other sets of instructions on the web for doing this with PhotoShop and comparing them to the Gimparoo! instructions (particularly these instructions). What I've found is that the Gimparoo! instructions are not entirely complete so I've decided to write my own.

How to choose the best Linux distro for you
Choice is the best thing about Linux. Without choice, we may as well use an operating system where the developers make those choices for us. As we've covered in the past, anyone can create a Linux distribution. If it is different enough, it will survive, but most disappear without a trace. There is a flip side to all this choice however, and that's finding the time to find the perfect distribution for you. |

ReactOS Project: React Operating System
The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This will allow your Windows applications and drivers to run as they would on your Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows® would find using ReactOS straightforward. The ultimate goal of ReactOS is to allow you to remove Windows® and install ReactOS without the end user noticing the change. Please bear in mind that ReactOS 0.3.9 is still in alpha stage |
Realizzare un sistema anti-intrusione con la webcam (5/10)
Realizzare un sistema anti-intrusione con la webcam (5/10)Scritto da Massimo Mazza il 27-04-2009 ore 11:13Una soluzione economica per realizzare con poca spesa un filtro infrarosso, che lasci cioè passare la radiazione infrarossa e blocchi la maggior parte della luce visibile, è quella di utilizzare una pellicola per diapositive: le classiche pellicole fotografiche per diapositive - la Kodak Ektachrome è quella più famosa.Onde poter sopportare l'intenso calore generato dalle lampade dei proiettori per diapositive, queste pellicole sono realizzate in maniera da essere il più possibile trasparenti alla radiazione infrarossa, e ciò vale anche per una pellicola completamente nera, la quale quindi bloccherebbe la luce visibile, ma lascerebbe passare le radiazioni infrarosse.Queste pellicole sono in vendita in qualsiasi negozio di materiale fotografico, e in alternativa alle Kodak Ektachrome, si può optare per un'altra marca, purché sia una pellicola a colori invertibile, sviluppabile con il processo E-6. Bisogna chiedere al negoziante l'immediato sviluppo, anche se può sembrare una richiesta anomala.Poiché il rullino non è stato esposto alla luce in alcun modo, esso verrà reso dopo 24/48 ore sviluppato e, ovviamente, tutto nero. Per chi non fosse completamente a digiuno delle tecnologie fotografiche classiche - quelle basate su pellicola, tanto per intenderci - ricordo che stiamo parlando di una pellicola per diapositive, invertibile, non del classico negativo a colori.Un negativo classico, se esposto completamente alla luce e poi sviluppato diventa nero, perché poi nella successiva fase di stampa il positivo su carta apparirà bianco. Se invece non viene esposto e viene sviluppato comunque, apparirà di colore arancio trasparente, dando come risultato di stampa un bel nero. Le pellicole per dispositive funzionano invece esattamente al contrario (donde il nome di invertibili): ecco perché, per poter ottenere una pellicola nera, occorre svilupparla senza esporla alla luce.Il formato più comune che sicuramente troverete in commercio sarà quello da 35 mm, ma se desiderate avere un formato che abbia una superficie più ampia, da cui ritagliare le porzioni di pellicola per i nostri esperimenti, potete provare con il formato 120, conosciuto anche come 6x6.Una volta in possesso del nostro rullino di pellicola nera, potremo iniziare a utilizzarla per realizzare il nostro filtro infrarosso e ottenere interessanti risultati, come vedremo nella puntata successiva.Programmazione.it :: Realizzare un sistema anti-intrusione con la webcam (5/10)
Tweet This Text: seleziona del testo e postalo su Twitter con un clic
Tweet This Text è un bookmarklet (un piccolo javascript che si piazza tra i segnalibri del browser) che serve a postare su Twitter del testo prendendolo direttamente da una pagina web.
Una volta trascinato il bookmarklet tra i preferiti si evidenzia il testo che si vuole pubblicare e si clicca sul segnalibro (che conviene piazzare nella barra così da averlo sempre a portata di mouse), saltando così un paio di noiosi passaggi quali copiare il messaggio, aprire twitter.com e incollarlo.
Niente di rivoluzionario, ma un modo decisamente più rapido di aggiornare i propri 140 caratteri su Twitter!

Reader Tutorial: How to create an awesome action picture in GIMP
This tutorial is a remake from a Photoshop tutorial, that can be found at http://abduzeedo.com/how-create-radical-photo-sequence. It was written by Paulo Canabarro. This tutorial is intended for people that have a general idea of layer masks, as layer masks are a big part of this tutorial.
Some things you will need before we get started: A few pictures, that were shot in the “burst” mode of your camera. (See step 1 for more info about this)
Step 1
The most important part about this whole tutorial, is having pictures that will work. To get the pictures that are needed, use the “burst” mode setting on your camera. On my camera (Sony) its found under the “menu” button. On your camera, it could be located in a different area. In a short description, the “burst” mode takes pictures for as long as your capture button is held down. There are some things to know about this option though. If your not in good lighting (at least on my camera) the photoshop will be blurry, which is why I recommend a well lit, outdoor setting. It's all trial and error, so just find out what works for you.
Step 2
Load all your photos into GIMP, and find your first image. This would be the one that's either coming in from the far left, or far right. In my case it will be coming in from the right.
Step 3
Find your next image in the order, and select the whole document (select>all) Then copy the image. Move to your original image (the one in step 2) and paste it in. Make this floating selection, and new layer by clicking the new layer button.
Step 4
Repeat for each image. Keep selecting them, and pasting them until there all in the document.
Step 5
You may notice that one image does not line up perfectly, that will be fixed.
Step 6
Hide all the layers except for the bottom layer, and the next one up. In my case this will be the background layer, and layer 1.
Step 7
Select layer 1. Make a selection around the subject, make sure to get any shadows that are casted by the subject. This is important when adding the layer mask. Right click on the layer that you just made the selection on, and add a layer mask. Make it a black layer mask.
Step 8
Your layer will disappear, but don't worry, we will get it back. Make white your foreground color, and fill that selection. There is the subject now in view, but without the background it originally was on!
Step 9
This part is important. If you don't click on the layer image, before you move the image to line it up, you will move the layer mask, which is not what we want to achieve. Make sure the image thumbnail is highlighted with white.
Step 10
Move your new selected layer, to match it up with the background picture. Don't worry if parts of it don't line up, you can fix it with the layer mask.
Step 11
After you have lined it up, select your brush tool, and change your foreground to black. Remember black hides, white reveals. It's all trial and error now, trying to get the look you like, perfect. Remember to reveal the shadows, to make it look good. You can play around with layer opacity, to easier view areas you need to reveal and hide. (Note: If your layer mask doesn't seem to be working, remember that you selected your layer, and unselected your layer mask in a previous step, so remember to reselect your layer mask by click on it in your layers panel.)
Step 12
Once you have completed this with your first image, complete it with all the other layers you have.
Here is what my GIMP layers looks like:
Conclusion
My layer masks didn't need to be changed very much because my images lined up pretty well.
You can do this tut with as many, or as little pictures as you would like, though I recommend more then 3 pictures, and not too many pictures that they are overlapping and you can't tell what's going on. I also did not use very many pictures, because the goal was to get the technique across.
If at all possible, use a tripod, it makes the lining up process a lot easier. This can be done with any kind of image that shows movement.
