Marks on pictures

[capt_hollywood]

G'day all,

This is my first time posting so be gentle! I bought a D100 about a year ago and have a query for the more experienced users. After using the camera only a few times I seem to have some contaminants inside the camera which of course are showing up on every photo I take, rather annoying!!

Is this normal, do I have to clean the camera regulary to avoid this. Based on how long it took to get the marks on the photos from new that would mean sending the D100 to a dealer every month or so!! I'm getting sick of using Photoshop to remove the blemishes on every photo I take.

Cheers,

Hollywood.

Is there a possibility that there are enough owners of D100 and D70 users for us to have a true interactive list? Or at least that we can answer individual posts directly were their email addresses printed with their messages?

I had the same problem with my d100 from changing lenses in less than appropriate conditions (Hey, I was daytona for the rolex 24 hour race!).

I ended up pluggin in my AC adapter, and following the instructions in the book to raise the mirror and used my baby's snot sucker bulb and blew off the CCD.

That cured the problem.

Bob,

There is a D100 and D70 list at

There are also lists at Nikonians.org for both the D100 and D70 if you're interested. Lots of good stuff there.

Hi, If the "snot snooker bulb" does not work and it probably won't because the dust has been on there so long, try this

Boris,

Doesn't the mirror, which seals the sensor element, protect the element from dust in the D70 as it does in my Nikon FM, N2020, and Nikon F?

It is entirely possible to get a fleck of dust on the film in a Nikon FM, N2020, or Nikon F. However, when the film is advanced, the dust goes with it. On a sensor, it accumulates and embeds itself in every image until removed.

Bob, I don't belive that the mirror in any nikon "seals". If you take the lens off and take a look, you can see see a gap on either side of the mirror and the shutter curtain behind. The shutter covers the sensor, but does not seal it. Dust is a never ending battle with any CCD camera. If you read the whole piece on CCD cleaning at the link above, you get a much better idea than we have space for here.

Larry,

I now use an Oly 5050, whose sensor element is sealed by the permanent zoom lens, so I don't have the dust problem. I agree, the exposed film frame carried away the dust as it was wound awat to the next frame. That will not be the case with the D70 I have on order. So, unless Nikon solves the problem -- which it probably can't -- we will need to clean the element manually. I don't look forward to it.

One other thought on dust, if you own a D100 and you shoot raw, there is a "Image Dust Off" feature in the Nikon 4 Capture software that works extremely well for dust that get's in there between cleanings. I know next to nothing about the D70, but I think you may be able to shoot raw (*.nef) files with it. Not only is the quality 50% better than jpeg fine, there is a nearly infinite amount of image processing possibilities. worth looking into.

That one one of several factors why I chose to go with a high-end prosumer camera - Nikon CP5000 - rather than an entry-level dSLR. I have spent a lifetime spotting prints and dealing with dust, and am glad to be using a camera that is sealed as well.

Other considerations were the magnification factor, for ex&le, that would turn my nice PC-Nikkor 28mm into the equivalent of a pretty useless 42mm shift-lens, optical rather than digital viewing, and remaining as much of a packhorse as when I was shooting film. It is a mobile and very discrete camera well suited to the way I am currently shooting.

A SLR is vital when shooting chromes for publication, since one must compose to the arbitrary 3:2 frame ratio. With digital or negatives, I can crop and compose to suit the subject matter, not the eye of the editor.

Thanks for all the ideas. I don't have an AC adapter but will have to look at getting one I think.
