Ed- I didnt mean to imply you couldn't get the image. I have no doubt you can.

Hey guys. I saw this on my own long ago, looong ago, one time from around the same area, but it wasn't on Santa Fe, it was even closer to the foothills. Monte Vista rings a bell...duh!

It seems to me that a reputable shootist like Immoos is going to put his best stuff up, which includes some of the rarest shots you could imagine. So why would he try to shop the photo? Makes no sense. What I'd like to see is a shot by Anders of Ed shooting the Dome! Ta-da! If Anders is unavailable, I volunteer!

Another shot worth trying, but lots harder, would be of the silo from the top of Half Dome. I am not volunteering for that one, fo sho!

Isn't that they way they caught Clinton? Some d00d hiked to the top of Mt. Whitney (might have been Longs Peak??) and he took a pic with a really powerful lens. He focused on the eastern horizon. I think it was an 800mm with a 2x teleconverter or something?

Anyway, he gets the pics back from the lab and ... low and behold, there was Bill Clinton ... passing a doobie to Mz Monica, on the Whitehouse's back porch!!

Of course, he claimed that he wasn't inhaling ... nor did he have sex, "With THAT women!"!

LOL!!

edit: Maybe you, (Jerry&Ed) cud check that one out also (from the Whitney/Longs, summits)!

Ain't no way. It's to big with respect to anything else at that distance.

what have you been inhaling splitter?

johnnyboy it has to do with the angular extent of the objects you are viewing in the scene. With a very long lens the scene is foreshortened...

LOL!

Good come back, Ed!!

edit: nuttin', just my twisted sense of humor, i suppose! ;)

i wonder what length of lens it would take to get that shot from Turlock? I think 'elcap pics' uses a 600mm! throw a 2x converter on that and I doubt it would still bring Half Dome that close. Maybe with a telescope lens hooked to a camera body like they use to shoot stars, planets and constellations, etc, eh?

EDIT: for instance; i have taken pics from the wawona tunnel with a 300mm lens and they did'nt come even near to looking as close/large as the OP pic!

SO, in regards to my comment in regards to Mt. Whitney/Longs Peak and Clinton, I was being facetious! becuz it looks photo-shopped to me!

This question is answered on the first page of this thread.
In Mungeclimber's post - you might have to scroll to the right a bit to see the lens size.

Also, regarding your 300mm - does your camera have a full frame sensor? It yields a "bigger" picture. Expensive, but many people have them.

I noticed the 400mm reference, but don't believe that would be nearly powerful enough! Like i have said, I have shots from the Wawona Tunnel with a 200mm and a 300mm lens and they are both tele's and fixed (focal length) at that mm (not zoom/were it could have been only partially zoomed in) and in neither shot does HD look that large!

edit: the shots i have were from an slr/nikon f3, from the mid/late 80's! I do have a digital camera today, but not sure how that would compare to my old film cameras vs the full frame sensors. the longest lens i currently use is a canon 70-200 f4 zoom!

plus, digital is much sharper than the old chrome slides (so i cud be wrong)!

You are right - Mungeclimber's quote was incomplete.
Check out the description on the original link:
http://www.flickr.com/photos/trimmoos/3294080995/
67.25 miles from Half Dome and in this image, shot at 400mm, the grain elevator is about 1.5 miles away. I took many other images with my Sigma 135-400mm and Tamron 500mm mirror lens. On an Olympus DSLR that equates to a 270-800mm and 1000mm field of view compared to a 35mm SLR. This was the one that had the best focus of all the ones I looked at.

It looks like he's using an Olympus E-3, 3648 × 2736 .

here's a more careful analysis... I have included the effects of refraction though these may not entirely correct due to the local atmospheric conditions over the mountains...


it would have been nice to have had a clearer day to pick out the peaks on the crest...

like I said, I'd love to go out there with Jerry, and anyone else who's interested...

but it is a lot less interesting than watching climbers climb, believe me... for a Moon rise the whole scene is usually over in not more than a half hour, after hours and hours of preparation for the shoot... and you've got to have the weather cooperate all the way to the horizon...

this is not so bad when you're standing in Yosemite Valley, since you've had a whole day to shoot other interesting things (well, not the whole day, but usually the best parts just after sunrise and just before sunset... and maybe something in between). but when you're standing out in a fruit or nut grove somewhere in the vicinity of Turlock it definitely strains the imagination to find something interesting to do... the air museum at Castle Airport looks quite promising...

the next opportunity for a Moon Rise shot is 12/25-27/2012 (Tu, W, Th) with the last date having the Moon Rise just at Sunset which holds out the possibility of having alpinglow on the crest...

the bearings are around 65º which, for Half Dome, puts the shoot location very far south, roughly 5 miles north on Santa Fe Ave. from its intersection with 59 (ten miles south of the shot above)...

To shoot Half Dome from the central valley is somewhat less problematic... but challenging none-the-less

Here's what last Saturday looked like from Ahwanhee Meadows

http://halfdome.net/ahwahnee_meadow/2012/ahw_2012_11_24.mp4

there was about a 40 minute window to shoot, with the clouds ending it... close call... Sunday was worse (I thought it might be given the meteorological conditions over the crest I spied on my way to Escalon)... the sky was fine until about 3:30pm then the clouds came in obscuring the Moon.

Since I had gotten the shot from Ahwanhee Meadows a few times in the past, and still haven't completed my images, I thought to do something different this last weekend. Now it looks like that will be the new obsession.

I can't believe there are so many people who think this shot is not real.


Back to the politics threads with you!

It looks to me that anything else at the same distance as Half Dome in the pic aren't near the same size proportionally.

It's huge relative to other objects equally distant.

I don't know if this website has been linked here. It is better than "hey what's that" at generating panoramas but it doesn't do the visibility cloak thing.

Ed-

I have a theodolite and tripod in the garage. It's old and not the most precise but it would work for identifying or locating peaks. Reads horizontal and vertical angles to the nearest minute and you can estimate to 6 seconds. The scope is 30x with a 1.5 degree field of view. I have California Topo! loaded on a laptop with a USB GPS so it is easy to calculate bearings from anyplace. One could relieve the boredom by setting up the theodolite, establishing a baseline and identifying peaks while waiting for the moonrise. Let me know if you think the theodolite would be useful or even just amusing.

Johnboy - exactly which objects do you think are equidistant?

Foreshortening....
