Hello,

I'm trying to build a pinhole camera that is easy to operate with my 4 year old. He really likes taking photos. We have a kids digital camera, and one that prints using heat paper (all black and white). I thought he would enjoy making one as a project

Does anyone have experience building one? I'm not sure how small a box i can get. I'm going to take a trip to Office Depot and UPS. But my main question is does the film width/height impact the F-Stop?

Basically I will have f-length probably something like 4-8 inches depending what is available and then the diameter of a pin. However, there might be a lot of empty space along the back wall where the film medium is. I'm going to run a regular film cartridge through on each end so I can do the trick where one film cartridge can roll the each other in and out.

So my question is if a 4-8 inch deep camera is too large, along with the back wall being much larger than the film frame is a problem?

How do you all teleport around to all the patches on lunar? I seem more limited in my locations I can go to.

Is there a route guide somewhere to hit as many patches as possible?

Tangent points

Select the bottom-left corner point of your new shape (the intersection of the curve and the straight line).

...
I'm following that guide. but i can't for the life of me select the POINT. Every time I manage to select something and i select tangent, the curve goes away, and setting to 75 doesn't do anything.

I've tried selecting with the pen active, but that just creates a new point, and is waiting for me to make anothiner point

I've tried selecting the yellow circle, pink circle with crosshairs, the yellow square. nothing.

I know im doing something stupid but i can't reread that sentence anymore.
