Long Exposure

Here are a few shots of street photography, I shot while shooting for the event.  Conveerted using Topaz Labs B&W Effects.  Enjoy.

This homeless man was given the opportunity to try his hand at street painting at the Lake Worth Street Painting Festival, in February.

White Ibis in Everglades National Park.

A self-portrait.  All work done in camera.  The exposure is 70-seconds.  I walked into the frame, struck a pose and stayed there for about 40 seconds, then waled out of the frame.

Ian:

Merco gave you the correct answer.  Here is a quick video, which is the only thing I can add.  Good luck.

Back to the original post, that started the thread.

To summarize the correct replies before the thread was derailed:

1.  The Bigma is cheap when comparing prices for similar reach.  Otherwise folks wouldnt buy it.

2.  There is no way the Bigma will resolve the 36Mpix sensor on the D800.  No way.  Nikon barely makes lenses good enough.  The Bigma is not in the same league as the "approved" lenses.

Now on to my opinions.  The Bigma is a slow to aquire focus lens.  I tried two models at the insistance of my local photo shop, since they are Sigma dealers.  I was skeptical when I walked out with the lenses.  I returned them two day and about 400 shots later.  It is just not a very good lens.

If you want to play the games that the big boys play with long lenses then you need the real toys the big boys lose.  Expensive?  Yes.  That is why there are rental houses for those who cant afford a real lens.  Period.

A superb piece of equipment.  I was lucky enough to direct compare the 4s and the Canon 1Dx late last year at a street painting festival.  I got to fondle these two cameras and use them for about an hour.  More than enough time to develop a love affair with the 4s.

Two quick observations.  Twwo things I wish Nikon would ship over to thier cameras from Canon is the jog wheel that lets you scroll through photos and I found that the Canon rendered skin better.  The second observation may be unfair as the 4Ds was not totally "set-up" as a the Canon was so perhaps it is possible to get better skin with the Nikon.

Unfortunately I did not get to use the cameras at crazy high ISOs which for me would be the test for the 4s, as I like to shoot in the dark.

Let's hope there are no issues with this camera when the production run hits the street, as there have been with recent Nikon bodies.  I doubt, or perhaps trust there will be no issues because I am sure Nikon understands it would not be good to screw-up their flagship.

Is there a new more robust, deeper bit-map *.jpg format in the lab?  Yep there sure is.

When will it be implemented at the conumer level?  No one knows.  Get out the crystal ball.  Your guess is as good as mine.

That's a lot of reach.

 Not really. Not if you are a birder or a wildlife person.

This morning was foggy at the beach.  A rarity for south Florida, USA.  Playing around with the fog and long exposure of course.  I offer the original photo and a second with a filter layer I added in PS.  Thoughts?  Make it a great day.

Serge:

I understand your point.  The crop I show here does not meet the usual rule of thirds you allude to.  That was a contcience decision on my part.  I wanted the ocean and the sky to have equal emphasis.  Besides look at a lot of contemporary abstract painting or photo work.  50/50 is the new crop.  Good observation but I will keep the crop I have. Thanks.

Gents, I have two engineering degrees.  Some folks call me a technology nerd.

Maybe this is what we need for the D7100 to squeeze a few more shots in a sequence..

280MB/S read, 250MB/S write. Faster than the current 95MS/s top speed ones I have.

OK, here we go.  Maybe that will work maybe it will not.  What is the buss delivery speed of the D7100, as I do not own one.

More directly, or perhaps more clearly, what is the fastest card the D7100 will work with?  I am taking a SWAG (a scientific wild-ass guess) that the buss delivery through put is not equal to the new Sandisk chip.  Therefore, not it is not what the D7100 needs.  Will the D7100 take and use the 128 chips that are available?

Let me look.  The Nikon D7100 owners manual on page 347 claimes a UHS-I speed as the fastest the camera can use which is 50mb/s.  So there you have it.

Now that that is settled.  What is the solution to the problem you allude to, which is the reason I do not have a D7100.  The short answer is put EXPEED 4 in the camera then stand back.  The EXPEED 4 digital engine is basically the differenc between a dual core and a quad core machine, through put is almost but not quite doubled.  That is what solves the buffer depth issue of the D7100.  Also, and I cannot prove it but I bet there is a firmware hinderance built in to the D7100 limiting clocking speed on the EXPEED 3 engine.  Also, all of this begs another question.  If Nikon does not plan to come out with a D400 camera - a pro level DX format - and will rely on the D7100 then why did they not put the EXPEED 4 engine in it?  Clearly, the EXPEED 4 was in the lab and under development already.

Now with all this getting a bit long, what is the purpose new uber-fast sandisk card?  It is for video bit rates, up to 4K of shooting.  DSLRs and most video machines are still playing catch up to 4K.  Sandisk wanted to be rist to market to stake out their ground.

More questions?  ask away.

The view from the beach on Singer Island, Florida, USA in mid-day light.  A 10-stop filter was mighty helpful on this shot.

Drag the shutter and pan across a 1.3 second exposure with a 10-stop ND filter and this is what you get.  Peace.
