hello people

have anyone of you encountered a weird phenomenon on where an image is being distorted when you view it in landscape orientation vs portrait?

this is the behavior in my photoshop and human subjects get distorted... anyone else experienced this?

hmmmm...... No... hehe.... :Grin:

have you been drinking?

No... hmm... even if it's Window's viewer

leandro, how distorted? baka naman sir basil's right? hahaha kidding.. can you post a screen capture?

the same reaction here...

hmmmm...... No... hehe.... :Grin:

&

have you been drinking?

hmmm are you referring to the edges becoming jagged when rotated at an angle other than 90 degs?

or the proportion becomes incorrect when you rotate it at any angle?

my lcd tv does the same thing- angelina jolie becomes oprah winfrey when viewed in wide aspect- hihihihihihi...

it does happen to my jpegs when rotating in multiply or sometimes with windows viewer (before I moved to OSX).

yes this is what's happening, the proprtions are different when in landscape orientation then changed to portrait one. no other manipulation was done, just plain image rotation

@sir basil
i think drinking crude oil may have affected my eye sight :D

Any image is degraded everytime you rotate, resize, or transform it. But you shouldn't notice any degradation/distortion on the first few times you do it unless you rotate it more than a dozen times.

hala kayo! the master has spoken!

Could it be your Display settings or Screen resolutions?

yes, it could only be due to display setting. perhaps the display is stretched either horizontally or vertically, esp if your using a CRT monitor.

Lasing lang yan si Leandro (Trans: Beer pa!!!!) :D

there maybe several factors... here are some of what i think:

<> You have a widescreen pc/laptop but your resolution is set to 4:3 (1024x768).

<> you rotated a panoramic image (or just a wide image). in my line of work, i've had several customers complaining about how their images turned out to be disproportional after rotating, when in reality its actually not. If you rotate it back, you'll discover that the proportions haven't changed.

verify by checking the before and after of the image's w-h.

<> corrupted dll file. reinstalling ps may solve the problem.

hope this helps!

if you use a professional editing program like adobe's or corel's this should not happen coz the program is not touching the file itself, until you save it.

well unless your work flow is rotate, save, rotate, save, rotate, save, then this is not impossible.

Even if you don't save it. Try to open an image (a simple checkered lines or circles is better so you can clearly see the effect) in Photoshop. Rotate it at 10 degrees CW 9 times (that would be equiv to 90 deg CW) and then rotate it back to original position by rotating it 90 deg CCW. Compare the image with the one before you did the rotation. Try it 18 times at 5 deg rotation and notice how the degradation get worse.

hhmm.. idk, i did the test you suggested but my images did not degrade. anyways... we're drifting away from the topic.

edit:

did some research:

<> turns out that mitz is right on this one.

I think were still on topic since the title is distortion as a result of rotation.

Try this simple image.

ill try this as soon as i get back home

thanks for the suggestions, i know i can count on DPP people!

4:3 image shouldn't have issues with a 16:10/16:9 display, just because a screen is wider doesn't mean the resolution of the display will be stretched or skewed.

Your fonts don't become wider if your viewing from a 4:3 screen or a 16:9 screen, why should your images?

The overall resolution is the same and is dictated by your video card anyway.

yup, i tried mitz suggestion...
IQ was degraded even with just one cycle of 10deg CW and back with 10deg CCW...

so the moral of the story is to keep the image rotations to the minimum during PP...

so it pays to get the horizon straight the first time...

Are you rotating too much nude pictures? Your PC has gotten dizzy because of this. :D

these 2 images came from the same RAW file, resized to 800 px at its longest end then rotated 90 degrees to the right for image #2, to my eyes, the boy's face is more "elongated" on the 1st pic, i dunno if it's just my eyes but the kid's face is not the same as the landscape oriented one which is the original orientation of the image

i also found a similar problem on the web, you can see it here http://www.adobeforums.com/webx?14@@.3c058119/5

he's also complaining abt the same problem as i am

Leandro: I grabbed a ruler and measured from chin to top of the eyebrow, both registered 8.5cm, they're the same.

this is not true in my case. i have a 12.something" screen laptop ( i dont know the ratio but i know that it is not 4:3) when i set it to 1024x768 and open an image on photoshop the image is stretch. even my windows are stretch.


**************************

@leandro: i've check the image properties (right click > properties)... hor: 800x533 ver:533x800. i think the issue is not photoshop or your image... it's either your monitor or (i hope not) your eyes.

here is one way (physically) to check again. if you're using a laptop, you can turn it 90 degrees so that the hor becomes ver. and from there you can judge if it's still the same proportions. (just don't let anyone caught you doing this... you may look stupid to them. lol)

Rob: Maybe 1024x768 isn't your screen's native resolution? Just wondering coz my 14" laptop isn't wide screen but my LCD monitor that I plug into is wide screen. Whenever I plug my monitor into my laptop, the videocard automatically adjusts the resolution to fit the wide screen display's native resolution (1440x900). If I open my laptop screen, it hobbles back to 1280x800...

Anyway, OT na tayo hehe, sorry bud.

Leandro: I agree, I think it's just the orientation that's skewing the ratio of the image in your case... I re-measured the photos on a larger screen, true enough, the distance between the 2 corner extremities of the eyeballs are exactly the same, nosetip to chin is exactly the same as well.

Kinda like the St. Louis Gateway arch... it doesn't look like it, but the span of the Arch legs at ground level is 630 feet, the identical as its height.

Leandro, same measurements, both landscape and portrait. Its just the brain is trying to deceive you, as in the landscape view, the brain tends to think of it as "longish". I tried to blend the two images using both landscape and portrait and set in different degress of opacity, same measurements. Nice piece of photograph for applicants (I.Q. tests)

leandro, now i understand what you mean....

and this could explain everything... optical illusions, mindtricks...

kencarpio, nice find. my eye/brain connection made me really think that the tabletops were of different sizes.

good lesson learned there.

ken you found it! i was scouting youtube for that video. XD

thanks sir dan... nice meeting you last night sa south shooters xmas party....


rob... with the power of google... eureka!
