Tee hee. I remember when they were hi tech. :)

Before that flashes were single bulbs you put into a metal reflector.

Dr John, I believe. Remembers the flash power era.

Actually, something bothers me about this...

The camera was obviously a film camera. You had to manually twist a knob 
to wind the film to the next exposure after every shot. I'm pretty 
damned sure it only had one shutter speed, and yet I don't remember ever 
taking over-exposed or under-exposed pictures with it. (Bearing in mind 
we're talking about a 7 year old child here.)

Similarly, I can't *imagine* that digital auto-focus technology existed 
at that time (or if it did, that they would actually put it in a child's 
toy), and yet I don't recall ever taking a photo that was out of focus.

Why is that?

How is it that 30+ years ago they could make a camera that's always in 
focus and correctly exposed, but today with the latest computer 
technology and 30 years of R&D into lens design, they can't replicate 
this feat?

Congratulations Andrew.
You have reached that age when the past was a “golden age”.
I had a box camera that only had a “sunny” or “cloudy” setting. And 
true, in my mind. They were always in focus.
Strangely, I only kept it as part of my hoard. I only ever used it once.
And I had a bellows type that had “mountains” for distance and “head and 
shoulders” icons.

It was a good first camera. The default lens was adequate.

I ruined a camera thinking poly bags would be waterproof. I recognise 
yours or the type. My school camera club had a few.

It's true. :-(

Ah, one of the ones I accidentally over-exposed. Yeah, most of them were 
just ruined, but a few of them just look really sunny, which is kind of 
appealing.

> And the water scenes

Yeah, even on this grey day, they came out quite well.

I think one of the tricks with HDR type tonemapping is that you can keep 
the local contrast correct all over the image (which makes bright things 
look bright) but the "exposure" can vary across the image. This photo is 
a bit extreme, but you get the idea that the sun still looks bright and 
the "shade" areas don't look black:

I got one a couple of years back for my camera, and it seems they also 
use them on pretty much any TV show recorded in a studio.
