Does anyone know if the Active D-Lighting of the Nikon D90 affect shots
done in RAW or just JPEG?

Well, in auto mode I think it underexposes a bit... not positive about
that but generally speaking no it doesn't change the raw file. I've been
using it for the first time and the raw look much different sometimes...
using the photoshop defaults. And you can add it after taking a shot.

What is odd and frankly unwanted is it sometimes increases saturation,
like yellow walls in the sun against dark backgrounds. It also
occasionally makes halo artifacts along high contrast edges.
I understand they had better software (licensed) which has been ditched now.

I've noticed similar experiences on raw files with my D300.  I will be
asking this question at photo-expo later this month. If I can get an honest
answer I will post it.

BTW have you upgraded your firmware?

No, it's a D500, is there an upgrade?

I do generally like the idea, most often I'm wanting to reduce contrast
& lighten up the shadows but I'm not convinced this is the way to go...
at least I have the raw files.

Don't know about other boxes. I can only say what happens on mine. I do all
of my shooting in raw. This Summer I took a digital landscape workshop with
Stephen Johnson.

He advised that the in camera contrast be set as flat as possible. then the
contrast should be increased in post processing, if necessary.

I highly recommend his book, it is well written, but not for absolute
beginners, as Kelby's are.

I purchased one of Kelby's books tonight:  "The Photoshop Channels
Book".  I did this because some comment in this (or was it another
photo group?) newsgroup on the subject of channels.  So far, I've only
read and done the project in Chapter One.

I am impressed.  I like Kelby's style and presentation.  I think my
$42 (including tax) was well spent.

I'm a bit hesitant about buying books.  I use Photoshop V 7.0, and
don't have an interest in upgrading because 7.0 does what I need and
know how to use.  So many of the books now available are written for
CS3 and CS4 and contain steps that are not the same, or not possible,
in 7.0.  The books written for the older versions disappear off the
shelves.

There are so many things to spend money on like books, Lightroom, and
Camera Raw (or similar) that you have to be a judicial in how you
spend.  That doesn't even include hardware updates.  I have to balance
these expenditures with my wish list for glass.

I certainly did not intend to knock Kelby. He does have a very easy reading
style and spoon feeds the material. But I see his books as the type I would
borrow from the library. I don't see them as reference material.

You can pick up the older version books for very reasonable prices, if you
cna find them.

Unless you are a pro with a need for rapid post processing, don't get
Lightroom. It is nothing more than Bridge on steroids. For the $200 you can
get an extra CF card.

I too have a limited budget. I agree that the best place to spend money is
on the glass.

I haven't been able to.  Not locally, anyway.  I'm an avid reader and
know every used book store in town.  I buy books from the "Friends of
the Library" used book store in the public library.  I stop by
Goodwill to check the used books.  Not for Photoshop books, but for
any type of fiction or reference book.  

Photoshop users don't seem to get rid of their old books.  They can be
found on Amazon, eBay, and AbeBooks, but I'm an impulse buyer and I
like to check out the book before I buy.  In this case, I went to
Barnes & Noble and paged through the book before I bought it.  I
wanted a book that covered the use of channels.

I use 7.0.  I don't have Bridge.  I used the trial version and liked
Lightroom, but I haven't gotten around to buying it.

Yes, that's how I shoot, and I usually don't increase contrast in the
end, which is why D-lighting is appealing but oversaturated areas and
halos don't jive with that approach.

Thanks for the info.  I too only shoot in RAW mode and tend to just use the
default conversion via ViewNX.  I really have no photoshop skills, but I
have made a few HDRI versions on photographs using Photomatix.

I'm gonna check out Steve's site and see about getting his book.

Now if I can just get rid of the purple ring that shows up in some
conversions....

Keep up your experiments. It's refreshing to see that others are not afraid
of trying.

There is a lot to learn from him. He covfers a lot of the history so you
learn why he suggests something, rather than a dictatorial, do this.

Can't help you with that.

Thanks.  I have some other experiments (and real shots) in my own gallery,
though I don't keep it was up to date as I should.

It all reminds me of the time 26 years ago when my father let me move up
from the 126 I was using to shot with his Pentax Spotmatic (the Asahi
version, not the Honeywell).  Rolls of 36 exposure film were my friend and
I tried every time to get those few extra exposures by being able to load
the film in the dark.  Somewhere I have B&W pics of leaves and covered
bridges.  Now if I want to shoot 300 shots on some weird idea, I do and it
don't cost me much other than time.

jpeg only.
there might be info stashed away in RAW to allow a similar
feature to be performed with an enabled RAW converter,
but in general you'd get the same by fiddling with the
curves adjustment in a normal converter.
