I tend to prefer this version of the image, portrait mode looks better to me.
It's not the same picture, it's another shot though.

I agree 100% ! Superb shot !

Today decided to go outside and practice some hand held shooting with the A 645 120mm F4 macro lens. If I can manage to nail the focus I should get some pretty good captures with this old beauty. All shots were taken with aperture at f11. With this lens mounted on a 645 film body the minimum focus distance is 39cm, approximately 15 inches. Mounted on the K-1 the min focus distance is about 1/2 that. The sea shell shots were all taken at about 7 inches away with camera mounted on the tripod. Up that close the DOF is only about 4mm @ f8 or f11 which does not leave much margin for error. I am really looking forward to having a great time with this lens.
The first shot of the rhododendron bud was from a distance of about 11 or 12 inches.
Second photo is a close crop.
Third shot of the weeping willow bud was from the same distance of about a foot.
Fourth photo is a tight crop.
Fifth shot of Natchez was taken from roughly 15 feet.
Best Regards, Bob

Hi Bobby - I had the 120mm when I had my 645... it was an interesting lens. I kinda ignored it because it was part of a bundle I got and wasn't the object of my desire, the 300mm was! So it sat at home mostly, which I now regret after seeing your Natchez shot, and I see it is a decent portrait lens. The 35mm was my absolute fave of the 645 lens line up... man, it was pure joy to shoot. The 300mm was special too, and great for back of the church shooting. The 80-160mm was a great run around the reception zoom. You just needed a sherpa to carry and load film backs and lenses for you and you were all set. LOL!
Great pic of the pooch, I really like the rendering.

To further understand what's going on with DPS it's interesting to look at the dpr studio scene with the following settings
Image comparison: Digital Photography Review

As expected from the Pentax explanation the odd "Tripod PS (Handheld Mode)" produces worse looking images than "Handheld PS (Handheld Mode). Look at the womans lapel and its clear that Handheld mode benefits from the camera moving. Another detail is that handheld mode picks up the horisontal lines in her headscarf whereas the tripod handheld indicates vertical eching (probably moire) I find it strange that dpreview did this Tripod ps handheld mode shot but it helps in understandeing that it indeed works as described.

This also suggests that it might be "true" pixelshift. The pixel level motion artefacts also suggest that the four shots are merged without being demosaiced.

The above is all amateur analysis and speculation.

The Pool of Asmodeus.


Quite a few steps involved with this shot.

Firstly I realised that F9, ISO 100, meant a 25 sec exposure for a pixelshifted image, this meant that some fern was moving/blurring even after Motion Correction was applied PP (RawTherapee).
So I knew to take a second shot that was higher ISO (1600) but same aperture to capture the aforementioned motion blurring fern more static.

These two shots were then stacked and masked.

Finally a 3rd shot was taken with 50sec exposure for the water, this was stacked on the aforementioned stack to bring about a smoother glossier water affect.

Lots more editing in LR and Topaz (Clarity and Adaptive Exposure) whilst unmasking the affect from the water to keep it with that glossy look (I find boosting clarity on the rocks is nice, but doesn't do the water too much favours, so I tend to unmask the water from that effect).

A labour of love indeed.

Still I am quite happy with the outcome, no highlights blown, a nice exposure and sharp in places (due to pixel shift) with movement only where I wanted it.

The Pool of Asmodeus..

A lot of work but the end result: 1) is worth the effort; 2) is so seamless I would never have guessed what had been done.

Thank you.

Normally I do not have to work quite as hard on a waterfall shot, a single pixel shift image and a slow mo stacked together is enough, but the falls I have photographed recently have been in poorer lit areas making ISO 100 pixel shift images harder if the intention is freeze fern and other plant life.

I agree portrait mode works better. I would be inclined to crop even more from the bottom. Great image.

A pity dpr did not "understand" how DPS worked before they tested it and declared "it is not what you think"

Haven't looked at this thread in a few days - lots of great stuff as usual.

Da*300 & tc1,4x

Great shots - especially the otter and jaguar.

One more of Ardvreck castle in the Scottish highlands - on a rather damp afternoon. D-FA 24-70.

beautiful scene - scottish highlands are on my short list of places to travel - now just need my kids to be a few years older

Forgotten in the Rain

I think I slightly prefer the color version, though wouldn't complain about either . Something about wet hair...

The trusty 24-70mm.

kind of a sci-fi vibe to these shots with the spherical shape of the gondola cars and the toning - I like it

The Pool of Asmodeus.

turned out quite nicely - always nice to have a lengthy editing job come together as envisioned!
