    "Well finally got a chance to get out and shoot my SK 60 TS"

    Please forgive my ignorance but does the "SK" refer to Schneider or what?
    thanks,
    Robert

    BTW, ya'll are making a convert out of me big time with these amazing images!

    Re: Technical Camera Images

    worked this image a hugh amount. was after the greenish stormy light,wanted the middle foreground to retain the light, etc. assembled from 3 panos, but had to crop vertically to keep the best parts of each. for example, i fi let the rh stacks assemble from two overlapping shots, i got an Escher-like balcony rail since the stack in one pano was closer to the outer edge of the image circle and distorted a bit. you can see this in the first posting. light was changing through the panos as the clouds moved so i had to crop out the parts i did not want to merge, just barely got the merge to overlap enough to work

    David Duffin is an awesome host!

    Castle Mountain, 3-image horizontal stitch. SK150, Alpa STC, IQ180. I shifted 18mm each way and then cropped off the edges outside the image circle. I gotta work on it some more, but wanted to post something and say, "Thanks David for hauling me around the last two days!"

    Ciao,

    Out of my element here. Didn't realize that these units could shift. THAT must be a challenge with frozen fingers.

    Awesome views Steven. Is this from the last dollar road lookout? I car camped there two autumns ago but the fires west of wilson peak ruined the sunrise view.

    Ed, exactly, well almost there is a road that you can get to on the other side of the airport. Almost got stuck in the snow, but worth the effort.

    Re: Technical Camera Images

    Very nice Jack - the first and last are my favourites..

    flat stiches really increase the utility of the lenses don't they ? - and I must admit combined with the ( elephant gun ) 80 megapixels - really deliver a lot of optionality to the landscape shooter in terms of post shot cropping etc..

    Dave and Pete, thank you. Yes, stitching 80 megs opens up a lot of doors towards adding utility to an existing set of lenses!

    Here is the obligatory Zabrisky Point shot. It was not a great morning, but we work with what we got...

    Another one from my Days With Duffin. 8 image focus blend with Helicon Focus. Focus blending is much easier when the water is at or below 0 c.

    Quite nice. I only have one question, on my display the image looks a little purple, is that on purpose? I personally would try to fix it by moving the blues a little more towards the cyan side.

    Re: Technical Camera Images

    Thanks Christopher. Yeah, it is on purpose. i remember a very "purple-ish" scene. Maybe that whole Purple Mountain Majesty thing...
    I appreciate the feedback. I did struggle with white balance on this, probably because my memory was affecting my judgement. Could be a good thing or a bad thing I suppose. I have a couple different versions, some more neutral. To be honest I don't think I've found the right one yet. I will ignore it for a few weeks and go back for a fresh view.

    Ciao,

    Re: Technical Camera Images

    Here's one from a cataloging project. AS Monolith, Rodenstock 135, IQ 180, f11, stacked. Yes, one of those subjects that only a collector could love, but technically interesting. Movements are doing what they should but note the distortion. How would one correct that? No profile for this lens in Alpa LC. Time to start shooting square grids and rolling my own or is there an easier way?

    I don't collect old microscope parts, but I find it interesting--but then I run a microscope lab.

    You can only correct a limited set of converging lines at once--you can straighten your vertical lines, but the other radial directions are still converging. In this case swinging your back will not help--round objects are a pain. For a single shot, the only solution is moving back and using a longer focal length lens or cropping. You can also combine multiple images.

    It seems your back is not straight (converging verticals) and also you seem be shifted/risen towards the edge of the image circle as I'm seeing rectilinear distortion on the cylinders top right. I don't think it's a lens distortion issue but where you've ended up.

    I would centre the lens/back and ensure lens/back are parallel, aim camera down to the desired comp, broadly focus where needed and then straighten lens/back to perfectly horizontal. Now tilt only the front to affect focal plane. That's about as distortion free as you can get it. There should definitely be no converging verticals. If you're still seeing the rectilinear distortion and don't like it, you might try tipping the back to vertical (so you use less rise), take two shots and stitch them, shifting only the back on a horizontal plane.

    Yes, the only solution is to take a longer FL, actually as long as possible when such round or spherical objects are to be reproduced without distorsion.

    Re: Technical Camera Images

    Every time I see a shot done on the 70HR-W it make my eyes bleed and my heart flutter....... do I really need another lens?

    Great work from everyone in Death Valley!

    Has any an explanation for the "Racetrack" rocks? (my apologies if I missed it)

    Hi Thierry,

    The rocks at the racetrack remain a mystery as to exactly how, why or when they move, there is no rhyme or reason. There are four credible theories, but the most agreed to seems to be extremely high winds -- though they do not know what the lubricant is. They have satellite imaged and geo-tagged some of the rocks and discovered some rocks move when the playa is wet while others move when it is frozen, while others don't move at all, but then some move when it is dry; some move a lot at one time where others do not move at all and then those do move when the first batch doesn't; big or small, some seemingly never move then all of a sudden make a large movement of several feet, others move minimally over regular intervals; some move in straight lines, others curve and still others make abrupt, angular turns; and the most confusing to the wind theory is some move in opposite directions at the same times.
