OK. I am still back in Mr. Crosby’s chemistry class 1961-63 where we learned that silver nitrate was a molecule, and was used in photographic film. And I believed that the molecules were either au naturel or changed by exposure to light. Even in those days I saw things in binary. Film crystals were either on or off. I had no idea that the emulsion could exhibit different characteristics. That changes everything.
Quite so, but MSPaint is about the limit of my ability to play around with colours! If it wasn’t for my signature this month, I would not have been brave enough not to ask!... MS Paint is not a photo editing application...
Fair enough. Perhaps it was true back in 1990 when my photograph-mad pal Rick tried to explain the difference to me.ChrisGreaves wrote: ↑20 Dec 2021, 11:51...Film then provides a much finer resolution of light values than can digital...No, that's not been true for a long time now.
OK. Of course, I see the advertisements for so-many mega-pixels as advertising bumf, meant to sway uninformed amateurs like myself.The amount of detail, i.e. the resolution, that a digital sensor can capture is determined by the size / number of pixels on the sensor. It's a bit of an over simplification but digital SLR cameras began to have better resolution that film once the sensors got to over 7 megapixels (MP).
And I am so old-fashioned that I still think of a camera as an array of elements, each with a soldered wire. Times have changed, and it is all printed circuits now, atoms sprayed onto surfaces. In 3_D yet!
And just like that a whole afternoon’s VBA programming goes down the tubes.If you want a good starting point on digital photography try these tutorials:
