Tilt-Shift Photography, or How to Make Everything Look Tiny

This is a large format camera:

Unlike your digital camera (which most likely doesn’t even need you to focus), or an old-school SLR film camera (which only needs focus, shutter speed, and aperture), a large format camera has a lot of controls. Check out how each piece moves in 3 dimensions in the picture below:

2 of the adjustments you can make are called tilt and shift. Without getting TOO technical, what you’re doing is moving different focus planes to interact with each other in a way that you can’t really do with other cameras, thus selecting a certain region of the film to be in focus. There are modern tools that can do this on modern cameras (even digital!) – for example, lensbaby.com offers a lens that can make those adjustments. What will this do for you? You may remember this picture from a previous blog entry:

So, if you don’t have an extra $350 to spend on a lens (ok, let’s face it, you’re going to use it to buy video games and Mt. Dew), you can still acheive this same effect with a Gaussian Blur. It’s a great effect. You take a picture of normal sized people and magically they become miniatures!

Select a round (circular or oval-shaped) selection around the center, in focus, portion of your photo. Invert your selection and feather it by a lot. 100 pixels isn’t too many. Select Gaussian Blur from the filters section and experiment with settings. Can you make a photo look like these?

Robotics: Not Just For Boys

I’m spending this weekend at Hilltop High School in Chula Vista, California, for the final round of qualification in the VEX Robotics “Elevation” tournament.  (For a quick rundown on the rules, keep reading.)

iD Tech Camps gave away a scholarship to the “Excellence” award winning team – Team Spyder from Poway High School!

The winning Alliance consisted of 3 teams, the rest of the matches were 2-on-2.  Check out the pictures – Robotics isn’t just for boys!

The ingenuity and enthusiasm I see at these tournaments is unbelievable.  We use the same kits in our iD Tech Camps RoboContenders class that are used for this tournament, and I can’t wait to see what this summer’s crop of roboticists comes up with!

Here’s a quick rundown on the rules, from the vexrobotics.com website:

• Elevation is played on a 12′x12′ square field. Two alliances – one “red” and one “blue” – composed of two teams each, compete in each match which consists of a twenty-second autonomous period followed by two minutes of driver-controlled play.
• The object of the game is to attain a higher score than your opponent alliance by placing cubes into goals, and by “owning” goals by having the highest cube in a given goal. Points can also be earned by “parking” on the platform or by “controlling” the bonus cube.
• A bonus is awarded to the alliance that has the most total points at the end of the Autonomous Period.

Use Adobe Bridge to Quickly (and Easily!) Make Contact Sheets

If you’re like me, sometimes it’s hard to get a good idea of what your best photos are when you’re looking at them on the screen.  Sometimes it’s good to get away from the computer, and look at paper.  While I always advocate “staying green” and avoiding paper where possible, sometimes clients (or grandparents) prefer things the old-school way.  Professional photographers use “contact sheets” which are sheets of paper with sample images on them, much like you may have seen “thumbnail galleries” online.  A contact sheet is a paper version of a thumbnail gallery.  Adobe Bridge features a really easy and customizable way to view just the images you select.

Open BR CS4.  Select “output” from the top row, and you’ll see a dialog box on the right hand side with multiple sets of options.  At the top it asks if you want to output to a pdf file or for the web.  According to what output options you choose, you can customize the way you want it  to show up.

You can see a couple of samples here; a contact sheet with 40 smaller images, or one with 20 larger ones.  You can choose whatever sizes you’d like, or use some of the more common presets.
