Lean Pickings (Modified)

These two photos are identical. The right hand one is a direct cut and paste of the left.

So why does it slant more than the left?

Or does it?

For that matter, the right hand photo looks to have a darker sky. Curious.

...

For Lucy, I have created a threesome photo. Looks weird. (Click to enlarge.)

  1. One of those photoshopped pics, I guess..

  2. This is known in optometry circles as the bifurcated linear parallel declinatory verticals effect or BLPDVE for short - pronounced "Blupdove."

    Either that or I'd be clueless...

  3. Thanks Paul. I think.

    Hliza: It is only photoshopped to the extent that I copied the LHS photo as the RHS. Therefore the pics are identical. No fiddling.

  4. Oh my! That's cool. Why *does* it slant more?

  5. hi lee, if one copies a jpeg and then pastes and saves it as a new jpeg, then some pixel information is lost in the jpeg compression process and so the new jpeg would not be identical pixel for pixel. Might that be part of the reason for the increased contrast in apperance of the one on the right? just one graphic designer's guess. big hugs snowsparkle

  6. I would suspect it is just an optical illusion. Even the darker colour is not really?
    It is interesting how the brain can be fooled by what we think we see.

  7. Just HOW much of the red stuff was consumed on the oataversary?

  8. Maybe you were leaning to the right and sitting in a shadow when you c&p'd it, Lee!

  9. Damn that blupdove. They really are the same! I just measured.
    We had a book with optical illusions in it when we were kids, but I haven't seen this one before.

  10. Kind'a looks like a (fingered) peace sign.

  11. That's clever. Did you suspect it would do that when you copied it? Intuitive blupdove!

  12. ...what would happen if you added a third one?

  13. OK Lucy. Done. I will add it to the original blog.

  14. Don't do this to me, Lee - I had to get up at 4.00 am this morning, do a round trip of 240 miles in heavy rain and pick up family from the horror that is Heathrow Airport. (They enjoyed their first time in Oz by the way).

    Optical illusions?..this morning's drive was enough!

  15. Would it eventually fall over if you did, say, 10 or 20 of them??

  16. Same for me, the sky turns blue-er!
