H3D50 + HTS + 28MM + Stitch

[David Grover / Capture One]

What about it? Please elaborate. and what about sharpness fall off? We've seen some captures with the HTS on the forum by now. showing the field of view or certain possibilities of use. But never a 100% crop of the edges.

Edge definition is excellent.  I will post some crops when it is not a holiday weekend and I shouldn't be on the computer!

Thanks for posting the Shift+Stitch images I think a comparison between that and a VR Stitch pivoting the whole camera on the EPP would have been more valuable exercise which I suspect would have given better results than the 'quick 7 image stitch' in post 3

Granted it would not have shown the potential versatility of the HTS but for a £3k investment the HTS's  killer app is not just stitching

It has to be with Perspective and Sharpness control ie  the Tilt/Swing features and the DAC integration.

for architecture, as this example looks like, not that useful - when you put the straight 28 mm shoot over the stitched image, you reward for the work of stitching 7 images is to my eyes, the same
images combined with some nice dark corners.

If goal is to kill time, then making 7 images and thereafter stitch them, is of course way more efficient than just do one shoot    - in this perspective my Rodenstock 23 mm seems as a bargain......

other subjects than architecture, it's probably more useful.

very best

If the only benefit you're looking for is a wider FOV, then there is little point. If you're looking for more detail then there will be a huge (7x/2 or whatever the actual megpixel difference is) difference in the resolved details.  You won't see a difference in a web image, but 100% crops will show the difference.

Hi Phil,

I agree.  Its killer app is not stitching.  The purpose of the 7-way stitch was to show the extent of shifting (rise, fall, etc etc) movements.

Apart from the architecture photographers using it?

Distortion is fully corrected based on the T/S and Rotation settings off the HTS, which are displayed on the camera, written to the image file and then used to match one of the 60,000 lens maps in Phocus (our software) to correct for CA, Vignetting and Distortion.

If you take the DCU off the back of the point-and-shoot adapter, and put it on a mirror-free view camera with non-retrofocus specialist digital apo-chromatic lenses, you get good sharp pictures without DAC software correction of lens aberrations.

This would, of course, work a great deal better if you would enable the live video feature on the H3D11-50, or give me my money back so that I can get a Sinar.

(I have suggested that Hasselblad UK might like to lend me a 39 Megapixel back until you have enabled live-video in Phocus for the 50.)
