Odd 3D glasses, photo's that pop: I was reading another thread about viewfinders and I said my problem was the lcd screen that without my glasses that the screen was out of focus...

I was reading another thread about viewfinders and I said my problem was the lcd screen that without my glasses that the screen was out of focus unless it was at arms length. Thinking about this i thought hmm diopter for the lcd screen. So I was messing about a bit using my reading glasses as a diopter initially quite close to the screen. Any way holding them back from the lcd screen so the screen pretty much filled the glasses lens i noticed something my photo's had this 3d effect to them. I had photo's of different animals and birds and they really were standing out from the backgrounds. it's a really 3D like effect.

if the focus was off it was off but the birds and animals have depth to them. This is so cool give it a shot i reckon a cheap pair of reading glasses should work.

I think i may work out a kinda jig to hold them in place, it looks really good :) It also seems to work in the navigator panel in lightroom. Not all photo's seem to work but some of them the subject really pops out the screen.

I was thinking just yesterday about why the manufacturers don't have the LCD change for our personal eyesight, like they do for the viewfinder.
I'll have to give your idea a try. As soon as I run on to some reading glasses.

Here is a pretty good example. just try to fill one of the lenses with the photo and look through it.

just some trees but if you hold reading glasses away from your face

Oh I LOVE this tree

The 3-D effect seems to be present when viewed with a simple magnifying glass, too.

Thank you rjay. Way cool.

That might make things simpler, reading glasses are pretty much magnifying If I sit in the dark with my reading glasses on watching a film the screen does seem bigger than it's 13"s

meanwhile a metal flight case has arrived containing

1 pentax me - super (which wasn't cocking the shutter but since a little application of ipa is cocking everytime) + leather case
2 2x teleconverters 1 is pka the other pk
1 50mm pentax m f2
1 135mm Albina m f2.8
1 28mm vivitar close focus f2.8 Vivitar https://www.pentaxforums.com/userreviews/vivitar-28mm-f-2-8-close-focus.html :)
around 3 camera straps several lens cases and some colored flash filters (but not the flash they were made for) a few filters i think uv, manuals, end caps, lens caps, body cap and the key for the metal camera flight case. Approcimately $45 paid + post :)

I found this discussion on a physics forum.

I think it has more to do with the magnifying glass distorting and bending light, and the slightest movement of this hand-held glass gives the impression that the image viewed has a 3D quality.

Could be or the movement of your head smaller images seem to work best with the glass closer to the photo than your eye.

It's pretty good fun anyway. It also lets me know if i hit the focus right because it doesnt work well if the subject is blurred at all.

I just bought one, just under 3" in diameter.

Looking at the gallery I found this great photo

The LCD cannot be adjusted to your eyesight - unless you want an image that is more blurry. The LCD image is as sharp as it's gonna get…assuming you focused your lens correctly. The only way to sharpen the image for our poor eyesight is via an external lens, i.e. Reading glasses or a magnifying lens. The viewfinder has this lens built in so you can adjust the diopter value.

Thanks.
I guess I was hoping for a built in (adjustable) lens over the LCD that would magically make the image sharp to suit most anybodies eyesight.

Well there are a few loupes around mostly they are in the way.

Personally i'm quite happy with my magnifying glass i just bought.
Well worth the $1.50 it cost me with 5x magnification, there is no question of sharp plus you clearly see the depth of field, I kinda wish I had one years ago.

If you want to see TRUE 3D on your LCD screen, without glasses check out the Fuji W3 camera. Incredible! I didn't think one was able to view a 3D image without glasses. I was wrong. Seeing this, I joined a stereo photography club. Fuji stopped making the cameras but you can still find them on eBay.
