Do you consider mattresses "similar things like that" ?

Depends on the physical process. Are you carving, casting, bolting or welding or using 3d modelling and printing … ?

If it's a physical cake.

If it's software we seamlessly add functionality to each layer as needed.


But not actionable?

Software is not like "building a house" and is not like a sculpture and is not like a cake because software is (mostly) notional not physical.

Yeah the point is about design philosophy. The physicality or not is irrelevant.

Demonstrate that is so. Provide examples that are not physical.

No. You just don't understand what I'm talking about.

Perhaps if you talked about software instead of house-building, sculpture, cakes …

I don't see the difference. Could you explain how the physical attributes change the analogies?

I can use simple find and replace to change a variable name. If I've mixed salt and sugar up, there's no undo button.

The physical constraints govern the development processes described in the analogies.

The process for software is not constrained in that way.


It isn't that "photography can be a lie"; it's that an experience can be staged.

The role the photo plays in your examples is simply to record the staged experience.

Please show an example.


> I thought fixed focal length photography was pretentious snobbery.

35mm (50mm on ASP-C) was faster (f1.8) and smaller and sharper than 18-55mm f3.5-5.6 kit zoom.

And then 85mm (130mm on ASP-C, f2.8) wasn't much bigger.


Seems to have missed VA Smalltalk aka IBM Smalltalk.

Cool, I’ll check this out and ser how applicable it is to Ruby, otherwise I’ll try to use CRaC with TruffleRuby

> Is it to replicate what he saw through the viewfinder?

The experience is bigger than "saw".

Is it to hint at what they felt?

Later, looking at a purely-2d-visual representation is a different kind of experience than being there.


If it's art, to induce a feeling in the audience, then I don't see why you need to restrict it to actual photos of actual things. Once you start tweaking the picture, you can make it feel like all sorts of things that it's not, or appear to be something it's not, so why not go the whole hog and just create an image with whatever tools you can? It seems like photographs some with some sense of legitimacy as being "real" even though photographers can distort how things look to convey some feeling. Susan Sontag's essay described taking many photos of a subject until they showed the right emotion. So you can make anyone look like any emotion by cherry-picking from a huge set of shots.

> I don't see why you need to restrict it to actual photos of actual things.

We don't need to, although in that case, we might think of what we are doing as digital painting rather than photography.

> some sense of legitimacy as being "real"

A photograph is a purely-2d purely-visual representation of what we inescapably experience as 3d and multi-sensory. It can be "a real photograph" but not "real".

If what we are interested in is a documentary representation then we are making some additional claims about how the "real photograph" was made.

> any emotion by cherry-picking from a huge set of shots

Once upon a time, in the age of film photography, photo-journalists did take a huge number of exposures and have someone else process the films, and then select particular frames from contact sheets. Digital reduces that cost.

However, when someone looks at a photograph, they bring all of themselves and a little of the photograph.


> we might think of what we are doing as digital painting rather than photography.

Yet there is somehow some sort of value in it being photography instead of digital painting. You see pictures where there photographer carefully planned for when the moon would be in just the right place next to some building or mountain, even travelling to strange places where such effects occur and patiently waiting for the right moment so they could take a photo that looks just the way they want it. It would have been much easier to just photograph the moon and the mountain separately then combine them on the computer. I want to understand the motivation for doing it the hard way. Is it the feeling of accomplishment for doing a difficult task? It can't be that it's more honest because telephoto lenses and other photography tricks make it less realistic, and can make the feeling different from what anyone actually experiences looking at it.
