Draw that Histogram?!
« on: August 20, 2013, 12:25:14 PM »
I have a new game I'd like to play with all you guys and gals out there.
I'm afraid its actually one of those educational games that is designed to enhance your photography skills in a round about way. Its like being a kid and playing scrabble etc, its fun AND educational..... Hopefully  ;)

SO, what's the game I hear you ask.
Well, I post a pic and you have to guess and then draw the histogram that it would represent.
After we've had a decent number of guesses then I'll post up the actual histogram for all to see and discuss.
I'm afraid you will have to do some of the heavy lifting as you will need to draw the actual histogram and then upload it as an image here in the thread. Can you do that? Just do it in paint or whatever, don't make it a work of art for the tate gallery.

OK, here is the first image to start us off.

I once prayed to God for a camera, but quickly found out he didn't work that way.... so I stole a camera and prayed for his forgiveness.

This can't be good. It requires thinking.  Not one of my stronger suits.  ::sigh::  :P
Take your camera with you dammit. You can't take your next "best photo" if your camera is sitting at home in the bag, now can you?

To be honest, I'm sad this hasn't had an uptake - I was really really looking forward to it....

The only reason I haven't is because I have yet to fully understand them - I mean I know them basically but not so much that I could come close to drawing one from the image...

Okay okay, I'll try!

Here's my best try... I'm not very good at drawing in paint. not too many deep blacks, but lots in the "darks", not much of the mids and then a spike at "pure white"(I think my far right side should be a little skinnier).

Nice first attempt! Glad someone tried.
Now Zubbuz you have no excuse histogram are essential for us photographers to understand.
Black on left, white on right and the amplitude is the amount of that colour/shade if grey.

Have a go!

I know and it is something that I have been meaning to sort out for ages...

I will just ask a question to see if I do have a basic understanding - if not I'll go read more...

OK lets arbitrarily (no units just numbers for the sake of a question) say the far left is 0 and the far right is 100 (ie <0=underexposed and clipped; >100=overexposed and clipped), therefore we are left with approximately 100 'brightness' values. is the histogram effectively just showing how many pixels essentially are at each of those brightness value points?

Exactly right!

Cool idea. I gave it a go in a really crude way but I think you will all get what I am saying here.
I'm an old film guy just playing catchup in this digital world. Help me out.

square root of 2:   f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22, f/32, f/45, f/64, f/90, f/128

Here's the answer.

I was hoping a few more would take part but I think that many out there may have looked and guessed but not bothered to post up a drawing of one. So its time to share the histogram for all.

I think drzenitram was almost spot on. Well done!
Skippy was pretty good however there arent that many whites and the blacks aren't really black

Anyone want another?
We could just describe the histogram instead of the effort of drawing one?
I really thought this would have been right up Andy Civil's street. OR was it too easy for you Andy? ;)
