Threaded tires should have the thread "arrow" pointing forward. The quick release lever *can* be on both sides, but usually it is on the left side of the bike. Check the original pic: quick release on the right, arrow pointing backwards => wheel should be turned around.

He should check the front wheel, it looks lie it is installed the wrong way.

Seeing the roof shape, I dare say: yes, you could have. It was a close call. Glad you're still among us.

You OK? What happened?

This is, in a nutshell, how I make my stereoscopic pictures. \end

With time and experience you will be able to eyeball the right distance for your picture. In doubt, take more than two pictures, moving everytime a bit on the left (or the right), then you try to paste them together in several combinations and use the pair that gives the best result. \13

We see in 3D with an eye-to-eye distance of 6-7 cm, and that is a good distance for close-ups. For distant landscapes I have used distances of up to 10 m. \12

Regarding "move a bit": the "bit" depends on the subject distance. The more you move, the more the 3D effect is amplified, but the more closer objects are difficult or impossible to view. \11

For parallel view, the picture taken on the left is on the left side, the picture taken on the right is on the right side. For cross view, it's the opposite: right pic to the left, left pic to the right. \10

Finally, I paste the two pictures together side by side to get the stereo image. This can be done in Gimp, or using command line tools such as the ImageMagick suite. \9

If necessary, I rotate one of the pictures to compensate slight rotational errors (background objects are a reference here). Keep in mind anyway that the brain can compensate little errors. \8

Then, I edit the pictures on my PC using Gimp: I superimpose them on two separate layers, and make sure that they are aligned (above all vertically, horizontal alignment is less important). \7

Now, to taking pictures. I use a normal camera (my phone, actually) and take two pictures of the subject: first picture, move a bit to the left or to the right, second picture, trying to keep the same framing, exposure, and rotation as the first picture. \6

I use parallel view, that is why I always publish parallel view pics before cross view ones. \5

In cross-view, you cross the eyes like you would to do look at the tip of your nose, and try to make the pictures superimpose. With this technique, the left eye focuses on the right image and vice versa. Honestly, I couldn't use cross-eye view to save my life. \4

You could use a paper sheet perpendicular to the screen, and centered in the separation between the two images, to help you: put the paper, put your nose on the paper, so that each eye sees a single image, and try to have the two images superimpose. \3

In parallel view, you de-focus your eyes, or focus to infinite, and let the images "float" until the left one superimposes to the right one. With this technique, the left eye focuses on the left image, and the right eye on the right image. \2

Let's start from the bottom. You might be able to see stereo pictures without any aid (not everybody can). There are two techniques: parallel view and cross view. \1

Now, this is a bit of a paradox, because #crossview is not my cup of tea...

Wonderful pic!

Who in their right mind would try such a solo with just one buttock?
On the other hand, who in their right mind would play an ass-solo?
