| p.57 #12 · Sigma DP2 Merrill: Have any of you tried it? |
On top of this I think Jede is perfectly capable to speak out for himself.
I actually thought we had this conversation over with, but I'll respond as you seem to expect it. I'm not very keen to respond on your posts, because as carstenw said, you have a confrontational style to express your opinions, which I feel leaves little room for objective rational discussion. I'm not interested in debating, so hopefully we can leave this discussion here. Additionally, I've been in a hurry for several days now with other things, so explaining myself here hasn't been the top priority. Neither do I really feel obliged to.
First of all, thanks for the replies concerning the issue. mortyb, contas and glacierpete, I will try some tricks mentioned by you in my future post processing. I have Nik's Dfine bought for noise removal, and one can get the effect minimized in Photoshop by using masking and brushes on the areas affected. It's a a careful job, but I've saved some nice images with it. I'll see how the output is when using SPP in the way contas described. I'm not yet feeling the SPP is giving me a "flow experience" that I have gotten with Aperture and Photoshop. Workflow feels a bit awkward, and I need more experience and practice in order to make it feel fluent.
It seems that the appearance intensity is dependent on monitor, calibration and knowing what to look for. We all have unique vision and visual thinking patterns, so for some it might be easier to see. My 15" Retina MBP has a pixel density of 220ppi, which is rather high compared to for example 27" Cinema Display with only 109ppi. It really seems to bring flaws out in a way no other display has before. I'm not eyeing images at 200% (or 300% zoom as you wanted to exaggerate), but the effects are visible when simply viewing landscape images in full screen in Aperture or Photoshop. SPP doesn't support Retina display mode yet (we just got Photoshop support in December, thank god), so it's hard to evaluate the results directly in SPP. I like to watch my images in full screen mode (again, WITHOUT zooming), because I seldom have the interest to print them.
Like I said before, my intention was to present an issue which I have learned to observe in many of my images taken with this particular camera. Reading at your posts, I sense that we are not even talking about the same issue here. Maybe I have described it badly, sorry for that, so I'll try once more. For the last time I hope. The problem is, that in some images there seems to be lines going across the image on regular intervals, which cannot be parts of the scene or flaws appearing in the specific environment. It's a technical pattern, that is most visible in bright even surfaces on dark scenes with long exposures, and in some sense also in outdoor photos with big sky areas and large even bright surfaces. On landscape pictures the lines are vertical, and on portrait pictures they appear to be horizontal. The dog image was just one example, and using juan's image as example might have required a better explanation. Here I've cropped the top right corner of the windmill image, and cranked the contrast to maximum. I see those very faint horizontal patterns here on my monitor, please have a look. They were visible even on unedited Flickr image, which is why I chose to use it as an example. If you can't see anything, then I'm putting this under the factors mentioned above, and you really don't have to be obliged to comment further. Click for 100% crop. Sorry juan for exploiting your image in this way
I know when to expect the issue, and it isn't visible on all of my photos. And the dog image is the extreme example, so we all should treat it as just that. Leaving noise control sliders on the middle in SPP seems to eliminate the issue on majority of images. It's not critical, it doesn't make my images worse, doesn't affect the fundamentals of photography, and most certainly isn't a problem for majority of the users. Still, it's there, and each and everyone can decide if it's worth noting. I'm new to Foveon sensor, but this is something I haven't experienced with my previous cameras, and that's why I brought it up in the first place.
This is my last response on this issue, as I really have better things to do (taking images for example). So hopefully we can leave it here.
