But anyway, regarding 35mm film "which is actually 36mm" you couldn't be more wrong, roll film is measured by its film gauge, that is, it is 35mm wide, hence 35mm film, it has nothing to do with the arbitrary dimensions of the film we expose.

Let me be more precise. The gauge (from edge to edge of the film including the sprocket holes) is 35mm. The area we exposed on a 35mm film was 24 x 36mm. That is the relationship that drives the "standard" lens.

I will research further on the relationship with cinema film.

Classic film before 35mm was 72mm but 35mm (which is actually 36mm) rapidly became the dominant film standard. If you use Pythagoras theorem, you will note that the square root of the hypotenuse (the diagonal on the film) equals the square root of the sum of the square of the two other sides of the triangle (24mm and 36mm)For 35mm format film that gives approximately 43mm. That is the perfect match for what the human eye sees. That got rounded up to 50mm for most purposes. I rather suspect you will find similar relationships with other standard film sizes, although I have never done the maths.

Great shot!  I don't know if the composition was improvised or not, but it works.

Jim

Thanks Jim. I was milling about at the front of the stage waiting to collect her, and saw her coming down. So, yes: improvised!

Cheers

This is my daughter leaving the stage. She plays violin with the National Youth Orchestra who were on stage for the entirety of the three concerts. This was the last one:

Abstract / Party time
« on: April 26, 2013, 06:43:06 PM »
I have been travelling an awful lot in the last three or four weeks, so have barely even dropped by the forum for some time... However, on my recent trip to LA, we went to a party at California Live, where I took my 5Diii and 1.4 nifty-fifty. Here are a couple of party time photographs:


2Y2A4218 by RCARCARCA, on Flickr

EXIF: ISO 10000, 1/5000 sec, f1.4 (you may well ask why didn't i turn the ISO down - it was late, I was in the wrong time zone, and had had a glass or two of wine... and in such circumstances you cannot believe how fast the glasses can move)


2Y2A4172 by RCARCARCA, on Flickr

EXIF (and excuses): as above


2Y2A4165 by RCARCARCA, on Flickr

EXIF: 1/2500 sec


2Y2A4153 by RCARCARCA, on Flickr

EXIF: 1/2000 sec

Thanks for looking. I may well post others from the trip on other sections. If you want to see more look here: http://flic.kr/s/aHsjERPw5N

Street & City / Margaret Thatcher's funeral
« on: April 17, 2013, 04:42:13 PM »
I don't particularly want to enter into a political debate on this forum, but I thought I would share these two that I took today as the procession passed near my office:


Second hand emotion by RCARCARCA, on Flickr

EXIF: 5Diii, 24-105 @ 105mm, ISO2000, 1/2000 sec at f4.5

Taken as the coffin was transferred from the hearse to the gun carriage.


:-) by RCARCARCA, on Flickr

EXIF: Exactly the same.

I did not necessarily warm to Margaret Thatcher nor did I agree with all of her politics, but I do not like the jubilation at her death. Nevertheless, I couldn't help myself and I had to take this photograph...

Comments (photographic rather than political) welcome!

Thanks for looking

Beautiful photo's. You were there in the right time of the day.
Did you do some post processing on colors?

Thank you. Some light processing in LR4, mainly increasing the temperature and upping vibrancy and saturation. But not too much (I hope!!)

I thought that was just great. You are inspiring me to try, but i might have to see my daughters both at university and get divorced before I could find the time...  :(
