Re: Resizing photos for Z scale
|
You need to find some reference object (or multiple) in the photo to give you a starting scale. The larger the better as any error you introduce in measurement will be less significant. Doors and windows are good since they follow certain standards.
Now it's a matter of ratios.
Let's say you have a 30" doorway in real life, and you measure it in the photo as 1.5" (most image software can give you as-printed numbers, if not, just print it with no scaling and measure the photo).
Divide the 'real world' by the size in the photo, then divide that by 220 (z-scale). The result is what you scale the photo by.
30/1.5 = 20
20/220 = 0.090909? (or 9.0909%)
(or all in one shot: 30 / (1.5 * 220))
Scale the photo to 9.0909% when you print (DO NOT scale the image then print as you will lose quality!)
Check your results: A 30" wide door, in z-scale, is 0.136" wide. (30/220) 9.0909% of 1.5"? is 0.136" (0.090909 * 1.5)

I know how to figure out scale from prototype to Z or another scale but has anyone taken photos or images and reduced them to 1:220 to use on their layout? I'm thinking something like finding a photo of the inside of a barbershop and resizing it to put in the window of a Z scale building to look like there is something inside. I'm trying to see if there is a better method than just printing a lot of different examples until I find one that fits.? _._,_._,_
