I'm afraid I don't have the best eye for these sorts of things and I
need advice.

I shot Tri-X 400 spd 400TX kodak, with a "Quantaray" R2 coloured
Filter.

I used (old, from a tin can, but still clear and clean when cut open)
d-76 developer and kodak fixer. Development time was per specs, (which
was I beleive 6 mins 15 secs at 70 degrees)

I then scanned the negatives with a nikon Coolpix negative scanner and
for the most part converted them to jpgs.

I'm not really too familiar with this film tho and what it should look
like (I suppose it should look 'good' tho right!), or the whole process
either.  These are from the second roll of film I've developed, the
first I loaded horribly and almost none of the pics were any good.

http://i2.photobucket.com/albums/y13/Nygdan/Experimental%20BnW/Image1.jpg

Is it just that there is far too much sky in this one?  I should've
increased my apeture f-stop?  Is it possible to tell the diff between
poor expose and incorrect development times??

http://i2.photobucket.com/albums/y13/Nygdan/Experimental%20BnW/Image5.jpg

There seems to be a distortion around the tree to the left, not the big
one upfront, but the smaller one behind it, with the shrub growing next
to it.  The distortion seems to be at the height of the shrub. What is
it?

http://i2.photobucket.com/albums/y13/Nygdan/Experimental%20BnW/IMG001.jpg

Boring?  Sure, however it seems to have come out alright.  Perhaps then
the issue isn't one with development, but initial exposure.

I don't understand why these two look yellow, and the sky in the second
one hurts to look at!

http://i2.photobucket.com/albums/y13/Nygdan/Experimental%20BnW/Image4.jpg
Considering how bright the sky looks in this one, I am surprised that
there is any detail in the dark rocks, or texture in the granite
barrier.

http://i2.photobucket.com/albums/y13/Nygdan/Experimental%20BnW/Image2.jpg
Similar, what can I do about that sky? Is it the filter that is causing
a problem?  I suppose I can use a circular polarizer eh? Any
contrastiness I am hopping to get from the filter I can acheive by
developing for, what, 30 seconds longer or so??

If you are asking if they were over exposed during shutter time - I couldn't
tell without seeing the film.  It could be that the exposure was correct,
the development was off.  I've had mixed results with scanning my B&W film.
I've found that it takes a few passes at diffent scanner settings then
combined as layers in PS to get the best results.  Mostly I get results like
you see here, but when I use the negs to make prints with photographic paper
I don't have any trouble at all.

It's difficult to tell, but it looks like there's plenty of detail in the
highlights in the last 2 images, so probably a little burning at print time
will make them work out.

If you haven't already, you might want to check out Ansel Adams' "The
Negative".  There are interesting techniques on over/under exposing and
adjusting negative density at development time to compress and expand the
tonal range.

Scanner settings?  Didn't scan on grayscale?

BTW, it seems really odd that your skies are so bright when using a red
filter.  Was it sunset or sunrise time?

Here's a link to the film you used.

follow up.  Hope it was helpful.  Cheers! :)

BTW, with a little levels work in PS and some gamma correction...

It's pretty contrasty.  Either the development or scan is my guess.

You don't seem to have any featureless dark areas, so your
film exposures are probably ok. You do seem to have a problem
with your highlights, which with darkroom printing would
mean that your printing exposure was too short.

I don't know much about scanning film, but I have heard that
some people find that scanning B&W negatives as transparencies
and doing the inversion and contrast corrections manually
afterwards works better than the default negative scan settings.

As a general rule with negative film, actual overexposure requires
really overdoing it. If you were to take a series of exposures
one stop apart starting from seriously underexposed then you
would generally find that the first few exposures are low in
contrast and lack detail in the dark parts of the picture,
these are followed by several exposures which give almost
identical prints, and these are followed by a series of
increasingly dark negatives which will also print if you
have patience, but may show a bit of a reduction in contrast,
and increase in graininess and a decrease in sharpness.
The first of the exposures which give nearly identical prints
is the "correct" exposure. Doing a series like this could be
a useful experiment for you.

A red filter will darken blue sky quite a bit, but will have
little effect on skies which are not blue. It will reduce the
effect of the kind of haze you get on a clear day where distant
parts of the scene are bluish. This "haze" shows up more in
B&W film with no filter than your would expect when looking
at the scene. It has no effect on white mist or fog.

This looks like the kind of mark you get when you get a kink
in the negative when loading it on to the reel. It will look
like a dark crescent shaped mark on the negative. Most beginners
have this sort of trouble when loading film on a developing reel.
With more practice these marks will become rarer.

As far as color casts...convert your scans to grayscale and they'll be
"pure" black to white.

The distortion looks like it could be a mark on the negative, are you using
plastic or stainless steel processing equipment?  The mark is sometimes
called a half-moon or thumbnail.

Try scanning as a transparency, then inverting tones and adjusting levels in
Photoshop.  Older scanner?  Try Ed Hamrick's scanner software:  Vuescan.  Ed
supports a lot of scanners that the maker's have abandoned, like my LS-10
Nikon.  He has scan software for Linux, too.  Not a recommendation but he
seems to know his stuff.  Your mileage may vary, yada yada.

Wow!  I was about to sell my slide scanner on ebay cause it was so crumby,
but I just got the best scan ever from it!  I'm really impressed.  I'll toy
around with it some more, but I'm pretty pleased.

It is practically impossible to get good images from scanned B&W
conventional film, for a variety of reasons. If you want to use film,
you must make prints yourself in a darkroom with an enlarger. To show
you what a good print looks like, see:

hmm, not much sense in me processing film in a dark room then. This is
asort of 'inherited' darkroom, all the tubs and equipement are there,
along with a large stock of developer.  I only had to purchase some
fixer, stopbath, and wash aid. Even the film scanner and slide scanner
didn't have to be purchased.   Not planning on making prints on paper,
paper seems ludicrously expensive.

I pay $30 Canadian for a pack of 100 sheets of 8x10 inch RC paper.
A pack of paper lasts for around 10 evenings in the darkroom.
For me this is a modest price for a recreational activity I enjoy.

If I'm going to be printing a lot from a single film, I will
usually cut down the paper to a smaller size. An 8x10 yields
2 5x7s or 3 4x6s plus some test pieces.

If you already have an enlarger, you should really give it a try.
I find it a lot of fun.

Peter.

Paper is ridiculously cheap compared to the price of a scanner and printer that
can give you output comparable to chemical processes.  Don't forget that even
with a computer printer you need really good paper to get really good results.
So you will always have the paper cost.

Work the chemical side for a while.  You may just change your mind.

And the printer paper I use is more expensive than the fiber based B&W
Ilford paper I buy.

I know a professional photographer who get superb images from scanned
B&W conventional films.  But, he goes to a provider with a very
expensive scanner and gets large digital files that represent fine scans
of the negative.  This is not the equipment that the average person will
have at home.

No, drum scanners aren't cheap. :)

Correct. The scanners that are availabe in the retail market for under
$1000 won't cut it...

OT, I know, but how did you digitalize those images if you don't like
scanning from film?
Do you scan the darkroom made RC/FB print?

OK, that's claer by now.
Looks like I'm the guy that needs triple confirmation befor I believe
something.
But it's great to observe that others adhere to the methods I use myself...
Purely by lack of good filmscanner and photoshop knowledge, I stuck to this
method but found out it's still the most usefull: I adjust my images in the
darkrooom printing phase and only carry out very simple overall contrast
adjustments on the PC after the scan.

Sort of feel I have to comment on scanning B&W negatives.  I am far from an
expert and have successfully scanned many varied B&W negs.  It bothers me
when I see it repeatedly said they can't be scanned and thus discourageing
new people from trying it.  I have used a nikon LS 2000 and 4000 ED and an
Epson 3200 for medium format and all work fine.  With certain automatic
features like Ice you get quite a few dramatic faileurs.  So generally I
don't use Ice.  I find a small amount of unsharp mask is fine though.

I use both RGB scans and Greyscale scans, scanning as negatives which gives
you a positive image.  RGB might be a bit better but usually greyscale is
lots of info.  I don't see where scanning as a positive would make any
difference on the film scanners but see where it might make a difference on
the 3200.  I haven't tried it yet but plan to sometime.

I find processing your own B&W film and then scanning to be a very useful
workflow althought trying to keep making SG prints too.  On a little Epson
printer with Epson Premium Glossy Photo Paper I get quite nice prints 8x10
that might be thought real prints.

Just want people not to give up on scanning Tri-X without trying it.

Agreed. I've done little else to be honest with my Tri-X negatives. I do not
think getting a good scan is any harder than printing.
