Has anyone had any experience using the low light noise reduction feature on the Nikon D100? I have done some shooting in low light (topside) and can easily see noise mostly after I make a Photoshop adjustment...sliding the Levels slider to the left causes the noise to get worse. Any suggestions?

Any software that one recommends to attack unwanted noise?

I will do some testing as soon as I heal from some scuba related surgery sad.gif , but thought I'd get a headstart.

Thank you for your feedback.

In PS, try Filters/Noise/despeckle

Well, that kind of thing happens all the time. I was just reading an article in the Lembeh Chronicle... laugh.gif

Spooky!

Check Fred Miranda's site. He has a PS plugin specifically for D100 pattern noise.

I use neatimage from 400-800 iso upwards on the 10D. It will work with any camera as you build your own device profiles.

You can also use photoshop to gaussian blur the a + b channels in Lab mode, but I personally am tending towards using neatimage.

Yes the injury was spooky. Let's just say that you could have made a movie about what happened to me. I was left out on a pennacle in big seas because the ponga crew did a miscount (South America). This was a sunset, losing the sun and currents sweeping way out to sea, 300 miles in the open ocean. I did a self rescue and was left bloody, two separated shoulders, and damn lucky I have almost 30 years of diving experience.

Like the tests say, don't ever panic!! and yes, three years later, I finally gave in and had some shoulder work done. I do look back and laugh, but when it was happening for 2-3 hours, it wasn't too funny.

The sink came in later when puked up the 15 beers I had when I was finally found.

Joe, that sounds like no fun at all. Where in South America were you? Sounds like the Pacific side with those long big breakers.

I was talkint to the Tackett's at a recent conference and Larry told me about when he was left at sea in Indonesia. His group had to swim for it and not all of them made it out alive...:-(

Hi James,

I was out at Darwin in the Galapagos. We were warned of swift currents at Sunset between the arch and the small island. And two others to the crews knowledge got swept away and were never found. My plight was simple. I had to make the swim from the arch to the island at sunset in those swift currents as we were losing the sun. The island has no beaches, it's really a vertical island, so I only had slimey boulders to use as hiking ground once I made the hour or so swim. NOW the fun really began because the crew was searching for me in the area I was no longer in, so it was imperative to make the slimey boulder hike to the other side of the island where the main boat was anchored. I was scared shitless that they would pull anchor and go join the search and I surly would have been dead if they did that.

The 'hike' caused the injuries when I climbed up the rocks with all of my gear on and my camera stuff. Pinning my shoulders on two boulders with that weight caused them to give out. One shoulder was locked and I had to grab it and yank it back into it's socket before making the hike. Hey, I had to save my camera stuff in case I was found :shock:

I used my sea sausage to tie around a boulder so I could locate my stuff which was burried in boulder crevices so it did not get carried away by a rising tide. The blood was from barnacle slashes while I hiked and climbed, but I really didn't know I had them til I got back to the main boat. Once I got close enough to the boat (maybe an hour or more of climbing and hiking), I shouted loud enough to so someone heard me and radioed the pongas that I was on the island and not out at sea.

The rest is history but we can surly say that it was an added adventrue I'd rather not experience again. I kept a log of the events and there is a lot more that happened but this is the basics.

It's amazing how you change and how focused you become when put in that kind of a situation.
