How to tell what bond a species is?

I know that shorter bond = strong bond. But how do we know which bond is stronger? It is like triple strongest, then double, then single? If so, how do I know if a specie is single, double, or triple?
Also, if a specie has a one single bond and one double bond, is it single or double?
What if a specie has two single bond and one double bond, is it single or double?

Answer by Aesop Ruvelas
Triple bonds are incredibly strong and close bonds. A molecule is not described by any average bond, but rather each atomic-contact is described. Dihydrogen monoxide contains 2 single H-O bonds. It is described as having 2 single bonds, not a single bond molecule. I hope that makes sense. Telling the types of bonds by names is much easier in organic chemistry, because it's a great influence on the naming system. There are basic trends that involve common sense. Such as BF3. It has a spot for 4 bonds. Three will be taken up by Fluoride ions, leaving a free pair of electrons. Those electrons are also open for reaction, but for now there's only room for single bonds.

Apparently Bond Chapel is difficult to get into, but on this particular day we were lucky.

Aligning Shots for Symmetry
How do you line up a shot when you are shooting in a place like this? I used to use a bubble level, but I've found that I can do a better job lining things up in live view.

The first thing that I do, is to make sure that I set up my tripod in the exact center of the location. If it's a church, I make sure that I am in the exact center of the aisle. Next, I zoom to capture the parts of the interior that I want to include. The most difficult part is to make sure that the camera is level. I use live view on the LCD and I keep moving the camera until everything is right. In the Bond Chapel shot, I kept checking to see the two outer lanterns were the same distance from the edges of the frame. I also check to make sure that the center line of the ceiling is running down the center of the frame. I have the grid turned on in live view and make sure that the center line is running through the center line of the interior if there is one.

When I get the image back to the computer, I will tweak it if needed. But if you do not line it up in-camera, it is almost impossible to use rotation tools to properly correct it on the computer.
