Easily find and delete BIG files that are taking up space on your Hard Drive

full-hard-driveEarlier today I tried to copy a large file I had made in Photoshop and I was told that the operation couldn’t complete because there wasn’t enough room on my hard drive for it. So, I needed a way to get a lot of space back, but I wasn’t sure what was taking up all of the room. I set about looking for ways to see what was going on on my drive and I happened upon some really great tools to help you visualize all your files. The process is called “Treemaps”.

I managed to find free Treemap programs for Windows, Mac and Linux platforms. For Windows users, you need to get a copy of WinDirStat (Windows Directory Statistics) HERE. Once installed, you can start it up and tell it to either analyze your whole drive, or specific folders. Here’s how it looks.

There is two options for Mac users. Grand Perspective (Gets up and going really quickly, easy to use) and Disk Inventory X (Longer to scan but a more thorough and detailed interface). Here’s how Grand Perspective looks.

And this is how Disk Inventory X Looks.

For Linux users, you can get KDirStat HERE. I havent tried it yet, but it looks very similar to WinDirStat. This screen capture is from their site.They are all fairly easy to use. Just roll your cursor over the big ones and the filename appears in the bottom left corner of the window. You can then decide which files you want to delete, and start enjoying some free space on your hard drive again.

3D Video – How Do They Make Things Jump Out Of The Screen – Parallax Width

narrow-vs-wide-parallaxI got an email from a reader asking how 3D movie makers make things feel like they are coming out of the screen. The best answer I can give is that to achieve this effect, you show a lot of depth and dimension when you are actually shooting the video. In other words, have a very distant background, and have the object you want to leap out of the screen positioned a lot closer to the camera. This causes the background to have a narrow parallax effect, and the item in the foreground to have a wide parallax effect.

Here’s a sample video showing the effect, and you will need your red/cyan 3d glasses to see the effect – Check it out! I Got’s me a block of wood Yo! BOOYAH!

Below is a screen capture from the video. If you look closely at the tip of the block of wood you can see that the gap between the left/red channel of video and the right/blue channel is quiet wide. This distance makes the object appear close to the viewer. If you follow along the length of the piece of wood towards my hands you will notice that the distance between the red and blue channels narrows. This narrowing gives the feeling of depth and dimension, tricking the viewers brain into thinking I am further back in the field.

Parallax-EffectIf this video was shot in 2D and you wanted to convert it to 3D, the perspective of the parallax (The Wood coming out at you) would be lost, and the effect would not be as dramatic. You probably could rebuild it using something like Adobe After Effects, but it would be a MAJOR MAJOR undertaking. The quickest, and easiest way to achieve this effect, is to create it and shoot it in 3D.
