    And that is why I thought it strange to see that one artifact.




    Perhaps these are my insane ravings. Or, perhaps I noticed something and simply wanted to ask about it.

    My browser has a protractor plugin. When I saw the artifact, I measured 3.3 degrees of correction. When I compared that photo to the one below it without a crop artifact, it measured *another* 2 degrees of rotation. So, +5 degrees of difference from photo 1 untouched to photo 2 below it (zoomed in). Just seemed not on the same horizon line.




    My wind-research spills over into that field as well as many others. Ha ha

    I just found it curious that the photo needed to be corrected in post when the mountains and angles looked just as good un-photoshopped.

    It was just a question. I don't see what is insane about the observation.
    i don't usually post in here, but i just read all that and thought "this guy is crazy".

    Most cameras have a grid feature you can turn on - I find this helps immensely when taking pics on slopes. Either line up best you can with horizon or a tree. At least now PG knows about crop and rotate! The more you know.
    Agree. The grid keeps things level. I think every professional should use it to keep things level.

    If, as Kalisto says, that the photo with the noticeable crop/rotate artifact was corrected for horizon, then I'd expect other photos to also be corrected for horizon. When I saw the picture I originally commented on, I thought "Whoa cool! That looks steep." Then I saw the rotated background artifact at the bottom corner and went "WTF?".

    Lee is a professional Instagram influencer with his own blog and much social media presence. I just want to know that when I see his pics, that they are real. Actually, it would be nice to believe that all the stuff posted in ski-zines is real.



    Let's see what happens when we adjust another photo for the horizon. After all, that is what was done to the other, right?

    Correcting that for the horizon makes it less steep. And the pole-planted is now vertical as is the ski strap dangling off the top skis. So that corroborates the rotation correction.

    What about the zoom action shots? Here is one picture. A split second later the same skier in a zoomed version. I assume they were rapid fire shutter press and zoom was applied afterwards. What happens if an object is used from the wide angle and a correction for the same angles is applied to the zoomed in version.

    Name:  jgLbkjb.png

    Correcting the zoomed pic to match the unzoomed pic results in it being less steep.

    I have no doubts that Lee or his clients can rip steep stuff. That's 49 degrees uncorrected and to rip that with a touring pack is quite amazing indeed. If they are ripping 49 degree slopes like that then I take my hat off to them and many kudos to them for seizing the opportunity.

    As a comparison, the average of drop + chute for Corbett's Couloir is 53 degrees. That includes the terrifying vertical cliff drop. So 49 degrees is seriously steep.


    Perhaps the steepness of the photo depends on latitude. That would explain why all the Aussie pics here are upside down.

    That's all I have to say regarding #rotategate. I'm a little crazy as everyone says. I just wasn't crazy I think to notice and comment on the rotate artifact a few posts up.



    Edit: A second look at the skier wide + skier zoom images. I don't think the top anchor image looks realistic either. After all, snow smooshes from skiing don't fall backwards. So, correcting for the snow-smoosh from the skier and the snow falling angle, I think 7 degrees is reasonable. That changes them both by 7 more degrees. Probably could be more than 7 degrees, but I'll give benefit to a little forward gravity since we are in the Northern Hemisphere. The lower of the two images, the zoomed one, is now corrected by a total of 12 degrees. Which make this image of both. Which still looks very good and very acceptably steep. Very good and very acceptably steep still. And I think the cliffs look right now too.

    Edit: But wait. There's more!! Here is a fix for "Alpine Skiing at the Durrand Glacier Chalet, BC" on a well known ski-touring huts photos page. Corrected so that the obviously flat cloud bottoms are actually horizontal. Line added to show cloud bottom alignment. Original photo here.

    PG I think you're crazy but that visual analysis was actually very interesting and informative.

    Do I care that the photos were rotated? No.
    Was I fascinated by the write-up and the fact that browser protractor plug-ins exist? Yes.
    Will I ever download or use said plug-in? Nope.

    Covid has brought mental instability in acquaintances. Then there's PG who's always been batshit crazy

    But I learned that doppler effect, red shift and lens flare can compensate for tilt rotation

    What’s awesome about tilt gate is that in literally every ski magazine and every ski movie ever this is a common trick of the trade to make things appear steeper as long as obvious give aways like trees or the horizon aren’t in the frame. Every single pro cine/Photog who made a living at one point making ski images does it. Pg has seen it thousands of times without ever realizing it.

    Great day all around.
    Good call on the early start.
    Let the masses ahead migrate to the known lines. While we skied a lesser trafficked N line



    If anyone wants to get out inclinometers for peak 2, and 3 here’s what they looked like that day. Don’t think I bothered taking a photo of peak 1 and the group of 8 not socially distancing, all lined up together and ready to drop in to the tracked NW face around noon.

    Look closely and ya can see Lee’s group.
    Can’t quite see if he is tilting the camera though-lol

    Got somewhat early at 8am to grab last parking spots. Not surprising for such a cold, clear pretty day.

    Lost the crowds by moving one ridge and one glacier over only seeing one other group. Got this mini-Gipfelglueck couloir to ourself and then mogulled the Berlin Wall (named the Borussia Dortmund Westfalenstadion wall today for special occasion)

    Powder and weather of acceptable quality

    The alpine

    Went back to the Summits and Icefields on Hesse this time to scope out the N Facing glacier of Rotenburg an def Fulda.

    We found the quality of views and snow again to be passable

    Warming up now. Time to focus on dumbing down trails
