How does one do HDR with the DP2 files?  None of the processors handle these raw files.  JUST do the merges on the 16 bit tiffs from SPP?? or is there another option?

Yep, just convert to tiff , send to Lightroom or Photoshop or whatever and your favorite HDR plug-in . Works just fine.

Juan,
banding in your pics might be a result of to much fill light combined with extensive curve bending in another program (Photoshop?).
I had a look at your pic of the beautiful pine tree at flickr. The colored version has no banding but the halos around the tree point to a fill light problem. Obviously the tree was to dark or the sky to light and you had to compensate for this. In such cases it's dangerous to use fill light alone. I almost always give the same amount of contrast when I use fill light. The picture looks  overexposed then and you need to compensate with the exposure slider. Over- and underexposure can be corrected with the highlights and shadows slider.

My rule of thumb is the following:  Contrast >= Fill Light = negative Exposure

Have you done the BW-conversion in SPP or in another program? SPP 5.5 is quite usable for that ;)

The banding is a hardware problem. It can be soldering around the sensor, electrical leak between layers, a bad electromagnetic shielding (maybe it is why the battery is so small), it seems to appear on a batch of sensors who might have a little default or another component around the sensor ... and so on. Be sure we will never know what is the true cause of this ;)

If it was only firmware and software problem, this would have been sorted Looooonnnggg ago.

Actually, it sounds like uvl just might have it sorted now....

Yes Hulyss, partially. This is a hardware problem for almost all digital cameras. It has to be dealt with more or less. Usually camera software is able to sort this out. The price for this are other artefacts.
Juans pics show banding only in BW-conversions. Color pics are OK even with 1.0 fill light. Maybe it's just a little bug in his BW workflow.

Thanks guys. I see banding always in my B&W pics that I procesed with Silver Effex. I think that this is the problem.
Thanks!!

A relative novice here.  What I know about photography could be rolled around in a thimble, but I bought the DP2Merrill last week and want to dip my toe into landscape and architectural photography.  I just hope I'm not the fool for having chosen such a persnickity instrument through which to learn.  I think it will be a camera that I can grow into and whose output I can enjoy immensely if I take a deliberate approach, and that is my hope.

It would not be my choice for a first camera only because there is a higher risk of less keepers, and because I think it lends itself to a smaller range of options then a normal camera, BUT, it will be a fun challenging trip for you.

For the heck of skin tones (FW 1.04):



Unfortunately, Flickr applies additional sharpness  >:(

Terrible skin tones on the DP2M!!!   I'm horrified....     ;D

What a lovely model.  Beautiful photo.

Hulyss, you sure they didn't fix colors w/ the latest firmware?  This example is lovely.

Thank goodness someone around here besides me posts Landscapes.

I was at Oak Creek Canyon last fall to hike and shoot.

Amazing place. Really, really beautiful.

Too bad I didn't have a Merrill at that time.

First time out with the DP2M.  I have no idea what I'm doing, but I'm having a good time.

What a gorgeous shot. Such detail!

Here is a link to a 9 image DP2M panorama of Cannes on the French Riviera.

https://dl.dropbox.com/u/9806585/Cannes_Panorama_Printready.jpg

The printed image is 24 x 100 inches at 300ppi

All images handheld, manual settings, stitched in PTGui.  The level of detail in the printed original is quite incredible.

OMG! This is absolutely gorgeous!

Gorgeous pano image! Due to the limitation of the 46mm lens of the DP2M I find myself to shoot pano more with the camera to get wider view for landscape images.

I like to know if you used vertical frames or horizontal frames to stitch this pano image? And did you use Nodal plate to move the camera a little bit behind the center of the tripod? Thanks! Here is the latest pano of the fall scene I shot the day before, 3 horizontal frames with DP2M.
