Originally posted by Lloydy Mag, I also have dyscalculia. I went through school branded as 'stupid' - then decided to become an engineer, because I love mechanical things. There's a lot of maths in engineering, which I couldn't do - unless I had the formula and a calculator. I could understand the concept and theory of something, but not the numbers part of it. I can't even remember my home phone number and it's been the same for 40 years. I can't add together a simple column of numbers or calculate the change in a shop.
But I can estimate the result of most things with surprising accuracy, because I understand the concept. Something that girl doesn't seem able to do.
All my number related tasks are done by estimation and 'pictures' in my mind of what I'm dealing with - that's a crappy description, but it's hard to describe how I see 'quantity'.
It's the same with photography, even after 40 years of interest and using SLR's I have no idea about the sequence of f stops and speeds, I just know the reasons for having them and know how they relate to each other. It's also why I almost exclusively use manual focus lenses on manual settings, I get to visualise the image, and make changes, before I press the shutter. With an AF lens and using Auto I have no concept of what the camera display tells me because it's showing me numbers. The camera telling me what f stop it's chosen is no use to me, I want to see if there's a big hole for a small DoF or a small hole for larger DoF.
The girl in the video had no concept, or at least very little, of the 'problem' - then compensated for that by over complicating the whole thing. Very interesting.
This made me laugh a bit. The home phone # that's me too. 30 years with the same phone for my folks and I still have to sit there and look it up on the cell or a piece of paper every time someone asks me. I don't calculate DOF and such via formulas. I've basically got a cheat sheet that I worked from books and with my teachers of the perfect settings to get what I want under what circumstances. That little DOF/aperture calculator on my Cruz pad it's a freakin godsend. I can calculate the change from money and I can add up columns with a calculator and figure out say the gross vs net sales for a shop for a day but if I have to put down some flooring, figure out square feet or figure out yardage materials for sewing I can get into major trouble. I usually buy lots of extra material just in case so I don't end up with too little if I end up cutting wrong. I hate sewing patterns, directions for things like crochet and knitting. If I take apart an item in my head to copy it, try to figure it all out visually as shapes, I can make a copy of a shirt or whatever and usually get it right. If I try to do it from a pattern, calculating properly I will usually screw it up. Same thing with home projects. I've put my bookcases and grills together by eying the pieces but using actual official directions can be a lesson in frustration.
Even with a formula and a T calculator there in front of me I can really screw things up. Word problems surprisingly are not much help either. I'm not too sure I can calculate MPH and how long it would take, how much gas etc if someone asks me. That kind of word problem used to completely stump me in college. I didn't get the formulas very well but I didn't get those word ones either which always surprised me as I'm so good with language things otherwise. I'm sitting here literally learning 3 languages via computer but I simply can't do a job in engineering or computer programming et all. I seem to be completely wired for reading and language but not for maths. I can sit there and read a wordy 500 page book in a time frame that simple boggles the mind of most people watching me but put a page of algebra problems in front of me and I'd be there all day and likely I'd never get it all done or most of it right.
