Interesting, and slightly different tonal range.
I have to start investigating digital dark room.
This one is slightly cropped.

D-200 with Nikkor 28mmf3.5 lens at1/250 sec., f8, ISO125.
Not quite FP-4, but still nice. I need to learn about highlight reduction, I think..

Image

There's a 50% crop there to pull up detail.
Note wood-grain detail on the backing board.

Image

Aphid infested elm leaf.
Nikkor 50 mm f-2 at 1/125 sec, f2 ISO 100 in the shade.
Not sure I like the out of focus highlights in the back-ground that much.
Like most of all my other Nikkors, this one settles into it's comfort zone about f5.6, or f8.
Taken from the balcony at Daughter's place on the 5th floor.
I don't normally see elm leaves up this close.
The lens was set at it's minimum focus distance for this one.

Image

50mm f2 again at 1/80 sec. f2. ISO "High 3",
which I suspect was 2006 Nikon-speak for ISO 3200.
Pixillation is quite obvious here.

Image

Same exposure details as above.
Snoopervisor on a late evening siesta.
These last 2 photos would likely benefit from photo suite adjustments.
Still, for what they are, from the slow processor and all, not bad. ;) :bigrin:

Regards,

Doc Sharptail

Some kind of flower taken with the 85mm f1.8 nikkor near sunset.
I think this was proabably about 1/60 sec. at f4 at ISO 125.

Finally continuing with the monochrome experiments.
These are with the current to me D-810, and show the advantages of an 8 year newer and 3 X the pixel capacity of the more modern sensor...

Image

!/10 sec hand-held here at f2.8 at ISO 3200. Fairly steady here after a big rib end pork chop supper. I braced my left elbow against the fencing here to stabilize the image a bit.
Nikkor S.C. 50mm f1.4.

Image

Pretty well the same thing here, except for 1/15 sec. The rest of the image data is the same.
Other than the high-lights being a bit on the drab side, this is almost acceptable.

In all honesty, I'm not too sure what to make of this.
First, and fore-most is that the rendering is definitely not the equal of B&W film.
There are settings on the camera to compensate for night-time high-lights.
It may be worth investigating further.
The rendering "feel" is a completely new one on me.
I need to look around a bit more and see how others are doing with digital monochrome.
Not sure I want to get into the light-room/photoshop thing yet.
Probably have more to add here after more experimenting.

Regards,

Doc Sharptail

i always shot B&W for me , i had a nice darkroom in my old first house , it was the coal room converted , i had a sliding bookcase for a door - when colsed you didnt know it was there , a small red light said i was "IN" and operating - DONT COME IN , i miss it but i dont have time anymore and cant stay up 15+ hours working it these days , had a lot of fun tho , had my enlarger on one wall with storage cabinets and all the chem trays in an 8 foot sink i built against the other wall , was actually quite roomy , i had closed off the coal shoot when i installed the upgrade electrical service that was bigger than my current house which is three times as big , anyway , i got off on a tangent - sorry

A little further experimentation.

In a well controlled setting, it ain't too bad:

Image
F11 at ISO 64 with the 55 micro nikkor.
Probably one of the few nickels left in circulation that actually has any nickel content in it at all.

Image

There's a good 80% crop of the image above.
Nice detail.
I still can't quite come up with a comparison to film though.
This medium is still pretty new to me.

Image
These look like pushed Tri-X here, by about a stop and a third.
Camera was set for ISO 200, f11 and 1/250 sec- a manual setting that I forgot I had entered into the camera. Nikkor Q.C. 200mm f4 at about 45 feet.

Image

90% crop here. I think a slightly faster shutter speed coupled with a pale yellow filter here would snappy this up quite a bit.

Still a ton to investigate here yet...

Regards,

Doc Sharptail

they look pretty sharp to my eye and seem to have good contrast , i always found tri-X to get grainy when you went ouside some of the parameters - but i shot a lot of it over the years

Tri-X was my most used film.
For most of theater work I did, it was pushed to ASA 1600.
I used speed T-grain developer- Rodinal was master here- at 1:100 for 16 min at 68 F.
Single shot with that low of a mix.
Rodinal reacted quite quickly to oxygen, and was generally not salvageable above 1:50.
1:25 lasted about 3 days in the refrigerator if I was lucky.

My favorite paper for that combination was Ilford multi-grade Pearl.
Contrast control was actually very good with Tri-X used in that fashion.
While a bit grainy, it never overtook the image like trying to push with fine edge developers.
I actually got as high as 16" X 20" before the grain degradation became noticeable.
Grain edges under the focusing magnifier showed deteriorated edges.

Regards,

Doc Sharptail
