should i work in adobeRGB?

Fievel,

Your understanding is correct. The parameter settings 1,2,3 only
work with sRGB. It is one of the disadvantages of using AdobeRGB
on the 10D. I've pretty much taken to shooting RAW and normally
process the RAW image as AdobeRGB primarily because I do a lot of
printing. I always convert my AdobeRGB image to sRGB for web
display.

If you shoot raw, you can have your cake and eat it too, but at the
price of storage space. In your instance you could shoot RAW+jpeg
and choose sRGB as your color space and you would have all the
parameter settings available to you. The embedded jpeg in the RAW
file will be in sRGB and use the parameters you chose. If for some
other reason you want an AdobeRGB version of an image, just post
process the RAW file in your favorite RAW processor and generate a
AdobeRGB image.
wow thanks jim, there very well may be times when i would use that option, for example if i know im not going to take a lot of shots on a certain occassion
that's a fantastic option
thanks for pointing it out

feivel,

It seems you may be slightly confused about color management between devices. The camera, screen and print output are all different devices and you are striving to get the best output from the camera and/or screen to your printer. Rather than go into a long drawn out discussion on color management I would suggest that you learn how to soft proof in Photoshop as a good start. Also, your devices need to have profiles that give you a starting baseline so that you won't have to guess.

As an example, for my Canon cameras (D30,10D), I have custom profiles that I use in C1 Pro. I can then tell C1 what I want my output to like for web, Adobe RGB, print, etc. Because my system from camera to screen to whatever printer I use is calibrated, I always know to a fair degree how my images will look based on output. I stick with AdobeRGB throughout as I am very familiar with how it fits into my workflow.

No specific color spacing will give optimal output unless all device characteristics are understood and incorporated into the workflow as such.
Hope this don't confuse,
VG
PS...The swan histo color space may be YOUR best bet....hehehehehe
Some folks like choosing 150dpi to print, rather than 300. Or like
always doing it in raw. Or like always shooting TIFFs. So...

Try both, and see if there's any difference.

Opinion:

I shoot JPEGs (not raw or TIFF) and sRGB. I publish on the web
(sRGB), and get prints from EzPrints. They look just fine.

The only advantage to using aRGB is the fact that it's a wider
gamut, so adjustments that you do, with levels, curves, saturation,
and so forth, won't get truncated. However, this only happens if
the adjustments are severe, so you'll probably never notice.

On the other hand, if you're targeting the press, where CMYK is the
rule, you'll definitely want to use aRGB. CMYK and sRGB cover
different ground, so if your working space is sRGB, and you convert
to CMYK, you'll see the loss. If your working space is aRGB, which
is effectively a superset of sRGB and CMYK, then you can convert to
either CMYK or sRGB without loss.

If you're not targeting the press, sRGB and JPEGs are simpler.

that's the answer i was longing for,
so to summarize i should do everything in s(swan)RGB, and then all will be OK!
 
seems to be the consensus....
but
i plan to get a canon 10d soon which shoots in sRGB (can also shoot
in adobeRGB but i dont plan to use that feature for other reasons)
my output is to the web and sams club for prints, both of which
should be in sRGB
so
since my input and output are both sRGB, does it make sense to
input sRGB, convert to adobeRGB, then convert back to sRGB, or just
stay in sRGB through the whole workflow?

--You are going to love the 10d. I decided to shoot in sRGB because there is a loss of a couple of functions in the 10d if you shoot in RGB but I am still experimenting.

i plan to shoot in sRGB also, would like to have the freedom to mess with the parameters especially the sharpness, dont want to rely on photoshop for every pic

what lenses did you get?

feivel
 
feivel,

The in camera parameters are a joke actually. If you shoot in RAW, it doesn't matter what the parameter settings are as these only affect JPEGs. The parameter settings in RAW are determined by the conversion software.

As to lenses, I've got the 200mm f1.8 and I don't leave home without it as most of my stuff is shot with it. If you got the money for lenses, stick with the L's. The 17-40, 28-70 and the 70-200 (IS or not) are all good choices. If not, probably the most versatile all around Canon non-L lens is the 28-135mm IS. It's the closest thing to an L that I've seen and used. Another good low end but sharp and contrasty lens is the 50mm 1.8 at around 60-70 bucks. Some of the 75-300mm low enders do pretty good as well for a zoomer.

Go to photodo.com for some lens MTF charting as they are fairly accurate as to real use.
HTH,

Just a comment about the 10D.

I was originally miserable with the focus issue. Then I reread the manual. I found that (1) if I used only the center focus point (settings choice), (2) had good light, and (3) did some in-camera sharpening, the results were/are wonderful. Obviously, a decent lens is a must. I'm very pleased now.

The focus issue has been discussed ad nauseam on the 10D forum, frequently with personal attacks and jibes. They provided much heat but shed little light. I'm sure some units were not up to par, but before throwing up one's hands, an exercise in patience and experimentation is worth the effort (at least for me) and is sometimes (even) helpful.

The 10D is not an Instamatic; there is a learning curve, to be sure, but (it seems to me) after a while, amazing pictures will just "pour out" of the camera.

The above is just my personal reflection/experience and opinion... "works for me" - so please no attacks on the focus issue.

BTW, the retouching forum is scads more interesting these days than the 10D forum.

This sounds like a good move. Once you learn working with the setting in camera, you'll be extremely happy with the results in Photoshop. I do a lot less fixing shooting with the custom settings and using PS to play with. By the way, I may have been confusing you because I never call the custom settings sRGB and that's what they are. I prefer to think of them as custom settings. I do always refer to these settings as "in camera, " so I don't get confused with PS Color Management.

hang around for a while, if nothing else you'll discover that there are no personal attacks here, the most civil forum around

I don't have a 10D or am I planning to get one, but your comments are appreciated. Since I lurk all boards occassionally and have read some of what you mention, on the camera. I think you have a good summary of what has occurred there and with the exception of those cameras that needed a factory fix, it seems the brighter of the users figure it out and the images they get are among the best available now.

--I do switch to Adobe RGB when processing and printing. After you get it, try my editing action. It is working well for me and I will send it to you. I got the 17-40L which acts as a 27-64mm and is a great lens. I got the 200 2.8f too which is sharp but not flexible. I ordered the 100-400 too and had to send it back for a replacement due to focus problems. The images are smoooooooooth!

..and this chart says it all, really:



I use a 10D (excellent camera, btw!), and AdobeRGB offers a wider colorspace and captures a tonality that sRGB simply doesn't have.
Choking the color space down from the get go is a shame, imo.
 
Well, not quite all. How do you display the extra colors? On a monitor? On a photographic print? A bit of a problem here.

In my case, I couldn't see any difference in the final outcome, and went with the simpler workflow (sRGB).

I don't want to start a "workspace war" here. All I'm saying is try both, and if you see a difference in the final product, by all means use aRGB. If not, consider sRGB.

Since I was moving over from (on the film side) A Pentax system, I had to start from scratch with lenses. I'm a nut about availabl light, and try to avoid flash whenever possible. My budget allowed me to get 3 good lenses which are:

Sigma 15-30MM 3.5-4.5 EX
Canon 50MM f1.4
Canon 70-200 2.8L IS

The two Canon lenses are incredibly sharp and contrasty and the Sigma is no slouch either! I am exremely pleased with my lens choices. This is after shooting over 700 shots on my recent vacation to Ireland/Scotland. The photos are incredible and the only problems were operator error :-)

My next lens will probably be the Canon 100MM f2.8 Macro USM, followed by some "big glass" -- either a 400MM f4.0 or 500MM f4.0 hopefully with IS. I'll probably have to see my car to buy that one though :-(
