More like sociopolitical commentary.

Art is whatever you make of it. Does it move you? No? Then it's not art FOR YOU. But it's probably art for someone else.

Hell, there's ALWAYS the art of selling art! That's an art form unto itself. In the case of graffiti, artists often do it for the ego trip. Others are lucky to be commissioned to do it for pay.

My son liked this urban landscape below the train station in our city. That wall changes all the time! It's opposite a parking garage, so it gets a lot of views.

It comes down to this: no matter how much we want them to be,
and no matter how convenient, profitable or modern it would be.....

some things can't be miniaturized without loss of quality and/or capability:
tractors, sails, pry bars, antennas, bass guitars, loudspeakers, cameras.

A tiny loudspeaker can be must as good as full-sized one--provided you
don't mind listening only to ultrasound.

And a tiny camera can be must as good as a large one, provided you don't
mind photographing only in ultraviolet light.

Size matters because audible sound and visible light both have a fixed range of
wavelengths. All optical systems have an aperture (if only the entrance pupil),
and so alll are limited by diffraction -- even in the absence of aberrations.

In addition, digital sensors have a finite (and not very large) pixel density.
igher resolution requires a larger sensor for the same reason that you can
only fit so many postage stamps on a given size envelop.

For a color sensor, it take three photocells to get one color pixel.

Scale matters profoundly in physics (both in classical electromagnetism and
wave theory--where shotrter wavelengths carry more energy-- and in
quantum theory).

But of course, there are flat-earthers are gravity-deniers...

Really good article. My camera is "only" a Nikon D3100 and by far the biggest limiting factor for performance is standing just behind the viewfinder. Maybe someday I will feel like more camera would give me better pictures, but for now at least working on my skills will help a lot more. [quote=Longshadow]Timing....

Very interesting reading, thanks.

Let me ask a simple question. If I have a Sony A7 and a Sony A6000 and I compose the same image in each viewfinder then pull the trigger on both, how much image do I lose on the A6000 compared to the A7?

I await your responses gladly.

The Sony A6000 has a 1.5 crop factor, the same as a Nikon DX body. Examples: https://photographylife.com/what-is-crop-factor

I came to a decision, at least my lovely wife did while I was out of town last Saturday and Sunday selling some collectible model trains. She has been looking at moving up to a Sony A7 II Full Frame for a while now and she purchase two of them on sale, one for herself and one for me. How nice is that, eh? We should have them by Wednesday.

My thanks go to the members for all the posts about Full versus Cropped Frame cameras, very good info.

Best regards.

"truthiness? Paul you need to invest in a thesaurus/ whoops. there IS a word truthiness. You learn something every day.
