I am looking for the scans of pages from 25 to 33 of E.B. Leaf book "Ships Modeling from scratch", where is described how obtain scaled drawings from photographs.

Can anyone please help me ?

find an object on the photo of a known size (hatch, life ring, scuttle(porthole),etc.) take a pair of dividers (or compass, whatever even a good ruler) and measure the item. EXAMPLE; Standard scuttle Charles F. Adams class (DDG's 2-8) was 22inches (I know from experience) take your dividers and measure (1inch) take your dividers and measure what you need (a gun barrel for example) it comes out to be twelve inches (I don't know the length of a 5inch 54 caliber mk 42 gun barrel off hand) 12inches x 22 (your known object) = 264 inches. Not quite sure if this will help or not. You can often find some known dimension from a plan (especially shipyard refit plans), then scale from there.

If you are try to determine the scale of the pic try the same thing but divide known dimension by size in the pic. For the example; 22inch scuttle/1 inch in pic is 1/22. hard to scale from pics because of the angles at which pics get taken.

Best of Luck
