    Re: Fun with MF images

    Trying to capture the grandeur of the Grand Canyon...a 8 panel stitch...reduced to 1920 pixels wide...the original image, after processing is about 43000 pixels wide.

    I guess images like these do not really work on the web.

    Awesome pano Christopher. The balance is too much!

    Those birds in the sky are the perfect compliment to the balance. Jaw dropper!

    Works fine on the web for me. I'll bet the prints are fantastic.

    Re: Fun with MF images

    A few with the H4D/40 and 35-90. Did a wedding in Port Sanilac Michigan on the shores of Lake Huron.

    Big house on a compound with 20 people staying there ... being an early riser I just went out in the AM to do a few personal shots and play with my new 35-90 ... which I absolutely love.

    I'm not a nature or landscape shooter, but must say I DO get the attraction ... it was so peaceful and almost zen like compared to the hub-bub of the wedding preparations and actual wedding itself. Getting paid to go on vacation is really cool ... LOL!

    Those annular rings in the OOF background highlights are NOT caused by diffraction (perhaps xpixel can confirm the aperture used and the ~magnification involved to confirm that there is no diffraction).

    Those rings come from the moulded aspherical surfaces in the lens' elements.

    Vivek, I'm merely an image maker and bow to your greater knowledge.

    Whatever the cause, this is the second image I've seen in the last week to be ruined in this way.

    Keith, I don't care what you call yourself but you are one of the artists I admire and look up to.

    If you are trying to say that bokeh from Leica glass in this example suck, I agree.

    It appears that sample variations may not show this annular rings. Sigma 50/1.4 lens for 35mm shows this and has been discussed with nice examples on the web elsewhere.

    Vivek, I really have no idea to the cause. The other image I looked at had come from the Pentax 645 but unfortunately the image has now been taken down from LL and I'm unsure which lens was used.

    Speaking as an image maker, this aberration, whatever the cause, would - save extensive retouching - render it unusable.

    The picture was made in at almost night with 70mm, ISO160, aperture 2.5, 1/60, SF58 flash...

    I like to see about the same kind of photo made with a hasselblad, phase or whatever... if there is also such a sharpness and color ... till now i think never seen here

    Frankly I could care less about the camera manufacturer and I'm not about to make any kind of judgement on this web jpeg regarding sharpness or colour.

    My sole concern was with the awful aberrations.

    Re: Fun with MF images

    looks like very bright pinpoint objects in the background, maybe more drops catching the light, are showing the bokeh effect

    Re: Fun with MF images

    Odd things happen with photography ... and this shot is an example whatever the cause.

    If it happened always, or a lot, I'd be pretty disappointed.

    IMO, apparent sharpness and color on this shot are more a function of the specular nature of the lighting, exposure level, and deep shadows as opposed to what gear was used.

    Thanks for the details. That appears to indicate the lens is nearly diffraction limited even at f/2.5 (ie., as good as it can get).

    However, there is more to an image than clarity as pointed out by Keith. While the 70mm lens may be good enough to photograph micrographs (and record all the details) from a distance, those highlights are unpleasant.

    IMO, "good" sharpness and color are relative terms, subject to the eye of the beholder. If *you* like that look, then you are in great shape! To my eyes, that particular image appears over-saturated and definitely overly specular as respects lighting (and/or processing -- I suspect the levels slider was crushed); then add me to the list of folks who find the ring pattern in the oof highlights disturbing...

    Man, there have been some great images posted here since I last visited! (I've been in the bush and out of wifi range!)

    Here's one from Quebec last week - 150 mm D lens.

    Thanks - you're right - it did and it does! You'll note the tree to the left is vertical and the camera was perfectly level. The building is tilting slightly.

    Bill
    I'm constantly faced with situations such as this.

    The point is we are conditioned to see straight buildings and tilting tree trunks. We can accept that wildly tilting buildings are indeed tilted, but when faced with a slight tilt our conditioning makes us believe that it was the camera that was off. In this case it doesn't help that perspective of the building looks un-natural.

    I'll often correct a slight tilt but accept there are those who prefer to not to. It's a very nice shot, but I couldn't live with the tilt and perspective.

    Re: Fun with MF images

    you know I think the tilt actually makes the shot something a tad more interesting than the typical landscape...a play on the eye..you know its the building when you see vertical trees and level horison - but you just

    Trees and buildings may lean but what can not be askew is the level bank of a placidly flowing river.

    Re: Fun with MF images

    Going back through some of my older images and found this one to rework. Original was from a Mamiya RZ67, 50mm lens and a 6 minute exposure on Fuji Provia, scanned on an Imacon. (The sand floor in this image is 'cottony' because other people were in the slot with me and continually walking through the frame as I exposed.) This is a recent rework of the original scan, converted to B&W and tweaked further in CS:

    love the tone Jack...love it in bw...can you share the camera settings?

    I was also recently in Page, and there were so many people there, its a pain to shoot. In Upper Antelope, I only managed to get 2 or 3 shots without people.



    Lower Antelope was better...it was much easier to get pics without anyone in it. Just for fun, the sun was low, and I shot a self portrait in shadow, and my shooting partner climbing the stairs.

    Thanks for the kind words!

    Camera settings were Provia film normally ISO 100, but rated here at more like ISO 12 due to reciprocity, plus I used an 81C warming filter. Final exposure was was f10 for 6 minutes.

    Beautiful image! At 6 minutes and f/10 it must have been pretty dark in there, especially considering that the slide film didn't blow the highlights. Not sure if it was the latest Provia 100F emulsion (RDPIII) which has excellent long exposure reciprocity with no corrections needed up to 128 seconds. But you really nailed the exposure spot on.
    Any reason why you've discarded the color of that film?

    Hi Dominique,

    It was the old, original formula Provia from about 10 years ago, which had pretty typical slide film reciprocity. It was early in the morning, so the light coming through the roof crack was actually very soft -- and yes, Upper Antelope is very dark as you get deeper inside. There are actually a few tiny spots that fully blew in the original near the bush, but overall a very tiny portion of the entire image. Re color, I of course also have the color version as well, but simply prefer this one in B&W because of the tonality and graphic nature of the composition.

    Here are a couple others in color from the same trip:



    This one was a double exposure -- first exposure was around 3 minutes to capture the walls and color, then about an hour wait for the sunbeam to hit the bush and a second, "Sunny 16" exposure:



    And then this one, which I also prefer in B&W -- that is sand slowly dribbling in through a crack in the desert floor above:

    I had a request for a different B&W from Monument Valley for a print so I went back to a P30+ shot I did and reprocessed it in B&W
