I'm trying hard to figure out the size of a fish from an old scanned picture.  This picture was part of a larger picture, showing me holding a large pickerel.  It's an embarrassing picture of me as a kid which is why I cropped myself out.  I think there is a way to figure out the exact size of the fish.  Assuming that the oar is a standard size wooden oar (from the late 1970s) and there is something standard about the way it is placed in the oar holder, somebody should be able to determine the exact length of the part of the oar, from the oar holder (from the base where it is screwed into the boat) to the visible tip.  I can then measure both that length of oar and the fish as they appear on my PC screen, (Edit - probably more accurate to measure in Photoshop) do the math, and determine the exact size of the fish.

 

Math is not my strong point, but this seems logical to me, so I have 2 questions:

 

1 - Is my logic correct?

 

2 - If so, what is the exact length from the base of the oar holder to the thin, visible tip?

 

Thanks

 

 

 

 

Why not try to use the distance between the rod guides.  I you happen to still have that one around or remember what type it was, casting or spinning.  If I had to guess, it looks like a 6'6" spinning rod (based on the number and space between the guides and how the one being used is being held with guides down) so if you measure one you have with the same number of guides, the spacing will should be very close to the same.  I think you can get much closer that trying to use that ore that has nothing to reference by.

Also the oar is at an angle so you may not get a proper reference for you fish measurement.

I never talk about the size of another man's oar.

 

Seriously it's impossible to tell exactly. The dip net sitting there is probably close to 2' long but it's farther away and you don't know by how much. 

exactly?

"probably" around 2' give or take

Thanks for the replies.  I just checked the original picture and unfortunately the back of the net is behind me, so i can't use this as a reference.  I don't have that rod anymore, but it was probably a normal spinning rod/reel combo, so if I can find something similar, I'll have something (the distance between the rod guides) to use a scale.
