H4D-50, 4 images stitched



Impressive shot.  What lens and stitching software did you use?

Beautiful, but you might want to get that Swan's Neck checked out :)

Here's my contribution.

70 stitched shots from an Alpa FPS/Rodie HR50/IQ180 from the pinnacle of the tallest man made structure on Earth:



Hi,

I guess this: (http://wap.bild.de/bild/json.bild.de/servlet/json/wap/28561512.html is you as well? Just saw it. I think it is the biggest German newspaper😃

Impressive shot.  What lens and stitching software did you use?

This was the 35mm and I used CS6's built in stitching.

Used a Lee filter polarizer and a couple of Grad ND's. I know it looks a little HDR but it isnt.

Took several whilst I was on holiday last week:

Chris,

I don't have the 35mm.  I use the 50mm HC Mk.II which I think is my sharpest Hassy lens ( much better than the old design) and the 28mm but for stitching, I now use an entirely different solution, a Sigma DP2 Merril, which is very compact and gives superb quality.  I won't post examples here as its the wrong thread for that.  I have stitched using the H4D-50 in the past.  I will post one I did a while back shortly.

Nice work though ;D

Thanks Quentin. As a travel lens I like the 35 as on a 35mm it's around 24mm equiv and I never like to go wider than that, I have the 50mm MK1 which tbh I haven't used enough to be bothered with, for some reason I never shoot at 35mm equiv. Weird.

How is the Merril, it seems a nice price for such a high resolution compact.

The Merrill is a life changer.  I have both the DP1m and 2m, and will get the DP3m when it emerges.  The Hassy is superior, obviously, but not by as much as you'd expect.  When I went on a photographic vacation for a week to Morocco last November, I took just the Merrills, a NEX -7 (which I hardly used) and left the Hassy at home.   Used the Merrills for stitched work, including interiors. I know I said I would not post a Merrill shot here, but it is relevant for comparison purposes, and anyway, this is a "fun" thread so here is a link to one of the stiched shots (warning: large file!).

Some fun in the studio with MF ;) HP5+ and Fuji645





(Edit - My bad I didn't seen correctly the tittle with "digital" ...) Take it as a 6x4.5 cm digital sensor  :-[

I will never stop to explain: film is DIGITAL because you can count the individual grains. You can use a microscope to confirm this easily. Everything you can count is digital. The differences between film and sensor are:
- Film grain is randomly distributed and responds in a logarithmic way to light.
- Sensor sensels are regularly distributed and respond in a linear way to light.

Consequently you are under the headline and can continue to post images taken with a HP5+ "sensor".

I wrote it recently in an other thread here: There is no analog in this world we know of. Everything can be counted. Sometimes the numbers a just very big.

Best,
Johannes

It is very very easy to get what you want. Just say: "Fun with sensors which have an orthogonal sensor layout and linear response". This rules film out. AND you could add: "Sensor must be bigger than 24x36 mm." This rules 35 mm out.

Best,
Johannes

p.s.: Quentin I just saw you are a senior partner in a Law firm. I'm absolutely definitely sure that you know how important waterproof explanations are ;-)
p.p.s.: Don't take my remarks to serious.
p.p.p.s.: I'm not a native english speaker, my apologies for any faulty explanations.

Whatever... *sigh*. Or focus on the word "fun" and stop fretting....

Sorry, we cross posted, see above. I had to look up "fretting" in the dictionary. I only find a technical explanation and don't understand what I should not do.

Forget the word "digital" in the thread title.  Make it "fun with medium format". It makes more sense to be democratic.

This I don't understand either, sorry. But infinity exists to my knowledge only in mathematics and for Buzz Lightyear.

Good night,

Sandymouth: H4D-50, 28mm HCD lens


Quentin,
Excellent depth and fidelity - this is a very nice image. You are making good use of the 28. Mine was returned today after a "checkup", so now I have to catch up.

Thanks, Ed, but what was the problem with yours?  I purchased mine used in a private sale.   It's a good lens.  And this is actually a two image focus stacked shot. I wanted to kept the sand pin sharp along with shoreline.   I have made the mistake in the past of trying to stop down too far with diffraction issues.....

Quentin,
The crispness of the lens was not quite what I thought it should be, so while this body and lens were still under warranty, I wanted to have it checked. Sure enough they found that the sensor was a "titch" off. We'll see how it performs tomorrow.
