before buying SD10

[tammons]

I photograph paintings too and IMO the resolution is good enough for 24x36 or larger. Actually it is so sharp it picks up the canvas pattern so you might print a canvas pattern on canvas, but it does work. IMO you could probably go up to 40x60.

My big gripe with trying to do this with digital is color. I have yet to find a DSLR camera that can capture all of the color of a painting 95% all of the time. One color or another is always off. Its tough and they all need adjusting.

That being said....

IMO the SD10 or fuji S2 have the most accurate color. The S2 is oversaturated and its a bit soft, and the SD10 color is a bit flat for me, but it will work and is super sharp. I am not sure about the D70.

I think the first issue is proper lighting, which I will admit that I do not have the best setup. Natural plus 2 diffused light sources from the sides seems to work best, but you must shoot a custom WB to get good results.

Next, I think a must is profiling your camera to those conditions to get more accurate color. I am in the middle of working on that one myself.

My biiggest problem with photographing paintings is glare. I use a polarizer which helps a lot, but there is still some there.

Here is one of my later glazed paintings shot with a SD9 and a polarizer

http://www.troyammons.com/paintings/painting%20pages/pear.htm

Iam an landscape artist,(oil on canvas) i take picture of landscape
and viewing it and painting it from my computer. after finishing
the painting, I will be taking picture of my finish painting to be
sent to a comercial printer who specializes in the production for
GICLEE prints.

(What is Gicclee?
Giclée (gee-clay') a French verb for “spurt of ink” — is an
advanced printmaking process for creating high-quality
reproductions of fine art. The attainable quality of Giclée
printmaking makes the reproduction virtually indistinguishable from
the original. Museum-quality Giclée fine art reproductions are
recognized as “the next best thing” to owning the original and can
be found in the world’s finest museums and art galleries.)

But to have a good giclee print, the image file should have at
least 300pdi for a 24"x30". 50MB of file for one print along.
Before buying SD10 I would like to know if it will meet my
requirements.

thank you.

Don,

for the sharpest and clearest image I'd go with fix focal lens.

like I said before, with the sigma, the 50mm is the defecto lens.

infact, it is one of the best 50mm around if not the best as far as its optical quality. the 105mm will give you a bit more working distance vs the 50mm.

here are some shots with the 50mm and sd10 which has some similarity of what you want to do by Champa. you can see the detail the SD10 and the 50mm provides.

http://www.pbase.com/champa/textiles

once again, to print 24X30 is not a problem. it's almost as simple as output as double size from SPP and resize in PS to correct dpi and size. like a few of us mentioned in this thread. it's been done with good results. and definitely look over carl's big print thread.

good luck.

here's a conversion chart for you.

A0 1189mmX841mm = 46.81"X33.11"
A1 841mmX594mm = 33.11"X23.39"
A2 594mmX420mm = 23.39"X16.54"

so you're requirement is very close to the A1.

and here's Carl's amazing prints:

would costs around US $1500:

I like the SD10, which I have, and you may be OK, but let me know
how large your paintings are, and at what sizes you could settle to
pritn them.

I think the SD10 and SD9 images can be printed quite large,
provided the originals are sharp and well exposed, and free of
noise.

and they looked great for me.
Carl Rytterfalk made A0 prints with great succes, may you search in
the forum for it, or at pbase where he have some pics online.

comparing to nikon D100 be OK, instead SD10 for my reproduction to
a 24"x30" ?

Ok first of all to clarify the printsize issue.

A0 is 33.11" x 46.82" inch (when calculated exactly) but imho if you got to a lab here in Germany and order an A0 print you will typically get 35.43" x 47.24" inch
A1 is just half that so about 24" x 35"

For some A0 samples go here:
http://www.pbase.com/kunming/special

Now the comparison to D100 or any other 6 megapixel CFA / Bayer DSLR. They might do better in very lowlight and so on but for reproduction work you should have the light under controll, once you have that the SD9/10 will really shine for reproduction work because they measure full chroma and luminace resolution (both at 3.4mp) compared to the 6 megapixel Cameras that record 3 million green samples (that typically make up the luminace resolution) and 1.5 million red and 1.5 mill. blue samples that are used with the green to calculated chroma (=color) resolution. What happens due to this is shown here with a 10D:

http://www.outbackphoto.com/artofraw/raw_05/essay.html

The test was designed to make the Bayer Sensor look bad but you get the point. The SD9 reproduces the blue/red transition far better and with less artifacts.

Here is also an estimation of the real resolution of the D100 compared to the SD9/SD10 that takes the AA filter and the processing of the CFA/Bayer Sensor in the D100 into account.

http://forums.dpreview.com/forums/read.asp?forum=1027&message=6503328

In short you get 2.2 million printable points from the D100 and 3.4 million from the SD9/SD10

And please, to everyone out there, stop judging resolution by filesize. It just does not work...

Yes, it will. I own the SD-9 and do Giclee output all the time. Some of my files are almost 150MB! I have done 20" X 30," but there is some softening at that size....very slight, and depends on paper, of course. I have never once been disappointed with my SD-9.

Good luck...

why there are only 3.4 effective pixel
in the sd10 or sr9
and 10.million photo senser detectors

will it makes a diffence compare to similar cameral

8 million photo senser detectors

Thank to everybody

i have read all your comments thank your. you have given me
insight about SD10
I am now positively convince to purchase online the SD10....
thank again to all

As you suggested I thought, why not try out the software on some .x3f samples, even from:

http://www.sigma-photo.co.jp/sd10/gallery/index.htm

I really like the foveon concept though I have a hard time truly convincing myself to make the SD10 purchase. I feel that this camera as well as most digital cameras need to have next to perfect lighting, lens, and lens use conditions to get the ultimate out of the camera. In the real world this means many shots won't measure up to what I need. I already have a digital camera that does this as a one setting or nothing picture taker. What I need out of the camera is to have clean colours, clean colour transitions, clean detail (not over sharpened) next to no noise in all values across the picture in most all conditions and settings without using too much image processing after the fact.

Yes, the SD10 is very nice though I am sure I'll wait until Sigma has a 6 megapixel times 3 sensor... hopefully this will give more possibilities.

Patiently waiting,
John

John

Check out my other posting on the D100 / pixelcount to get an idea of how this relates to resolution.

There is more about that. The coolfip8700 Lens is very likely not suitable for serious repro work. And the ISO is even very limited by noise.
