One of my favorite Bokeh lenses is the Nikon 500mm reflex telephoto lens. The "Mak" style with a rear primary mirror and a front secondary works a lot like common compact telescopes. The Bokeh is tricky to apply, it's a fixed zoom telephoto lens so your subject must be at least 10 meters or so a way and it's hard to handhold, but the "donut" aperture of the lens makes for some very cool (or weird depending on your ta…

Almost anything can be used well for artistic effect. Here are some shots from the Nikkor 500mm: http://www.indeed.co.jp/blog/scrap2/lens/reflexnikkor_500mm_...

This is a lovely example, thank you for the link!

And its all done in software (or ML) with recent phones to get around the lack of a good lenses system. And for most people it seems to work satisfactorily. This has been one of the complaints against camera manufactures recently, that the firmware on the cameras is wildly archaic.

If we're talking about non-point and shoot cameras, such as DSLRs or Mirrorless Cameras that cost $500+ such as my Sony A6000, I absolutely DO NOT want post-processing done on my camera. Portrait mode on my iPhone 7+ looks okay at a glance, but thinks like hair, wires, and twigs are TERRIBLE on closer inspection. Not to say the software couldn't be improved. For example, after taking a 20 second exposure, I have to w…

yeah its called an iPhone 11 PRO

It works horribly with hair and sharp edges even on the flagship phones. Plus it can't possibly work correctly with transparent and semi-transparent objects like glass.

My main complaint isn't that it doesn't work through glasses, but rather that it can't handle the frames at all. They are always blurred if the photo isn't taken from directly in front. It's a bit surprising as so many people use glasses -- a third, maybe? One could think that to be a major use case.

My understanding is that the processor on the eleven, eleven pro, and eleven pro max are identical?

Your definition conflicts with the author's. 1st paragraph: >as I own this site, I get to define good and bad Bokeh for the purposes here! The other key term is “image.” Bokeh is a property of IMAGES, not a property of LENSES.

not sure why I'm getting downvoted here for simply pointing out the author defines his definition of Bokeh in the 1st paragraph.

Whenever bokeh is mentioned in /r/pics, they are usually talking about the blurred background in an image that has shallow depth of field, not any particular quality of light in the image. Drives me nuts, but not worth arguing about.

Ugh, most people probably eat fast food three times a week too.

As a very nearsighted person, I can see bokeh if I take off my glasses and look at points of light - either nearby small lights, or far-away large lights. Also, when I look at a bright sky through a tree's canopy, the canopy transforms into a breathtaking mosaic of bokeh, which becomes animated if the tree is swaying in the wind. Can people with normal vision experience this?

I have good vision, and I can see good bokeh if I focus closer than the objects I see, and bad bokeh if I focus farther than them (which is much easier to do).

The delay after taking long exposures is caused by the camera taking a dark frame with the same exposure length as your actual image. When you take a long exposure, the sensor can exhibit noise caused by "hot pixels". The dark frame is taken with the shutter closed so that the camera can get an image of just the hot pixel noise, which it then subtracts from your actual long exposure.

You can turn this off in the settings, but I imagine it's way easier for the camera to correct for this specific kind of noise than for Lightroom to do so.

I believe it kicks in once the exposure length is >2" on my Sony A7ii.

Lots of mirror lens bashing :(

Bokeh is subjective. While the rings instead of filled circles resulting from a mirror lens look worse in many cases, I have seen cases where the 'rings' actually add to the image.
