The "Dirtiest Sensor" I've ever seen
I think he should invest in a yard broom and a shovel!:lol:

It doesn't look like sensor dust, but if that is the environment in which he keeps his stuff, I've seen enough regardless. :roll:

That's not sensor dust, it's too well defined. Sensor dust manifests itself as grey 'blobs' on the image. That looks like dirt on the image, which could be a scanned photograph.

Most definitely scanned negatives.

But the dirt's in the same places on each shot so they're not scans... :?

Hrm that's a good point :) Crud on his negative scanner? One of those £40 ones with the webcam inside.

Could be! I've never used one of those but wouldn't the constant movement of negs through it knock the dust into different patterns? Also, would a hardcore eBayer really use film? Not that there's anything wrong with film but for convenience it's not a patch on digital as we know... :wink:

The "Dirtiest Sensor" I've ever seen
I'm not sure, I have one of those scanners and the negs go in a plastic caddy which is maybe 5mm thick, so I doubt it touches anything. Not sure if just the airflow of the caddy passing a few mm away would rearrange the crud. If it's anything like the airflow needed to shift some of the crud on my d...

I can't imagine any ebay seller using film. The marks are also on his hands so it's not dirt on the table :oops:

I can't imagine any ebay seller using film. I suppose you could use a 1 hour lab and then get a CD with the prints, but it would be very much the hard way to produce pictures for eBay!

Dirt on the sensor does become well defined at very small apetures. There's no EXIF info in the images, but I'd guess they're at f32. Maybe the guy uses his camera as an ashtray?

Shutter Blur on K7
I've done a very quick scan of this and they seem to be discussing a phenomenon that they have described as shutter blur. They do stress that this is not something that is pecular to Pentax cameras, although they used a Pentax to demonstrate it. The hypothesis is that the movement of the shutter ...

Shutter Blur on K7
It's (might be) sympathetic resonance, IIRC, it can happen with many systems where the resonance is triggered and amplified. Bridges, musical instruments, sprung loads etc etc can all suffer. I guess the sensor is mounted on some kind of dampened mount, sprung perhaps with something to move ...

oooooh, errrr, Need to get a bigger tripod. oooooh, errrr, I need to get a bigger brain ... or attention span. :lol: No Mike, skip to the last line in the layman's summary, just like a real exec. "It's not about vibration or a „loose“ image sensor and a massive tripod prevents it." Chea...

Photography or Graphic Art?
Creating your photo in post processing is as much part off photography as selecting the right aperture and clicking the shutter. How ever you turn it, you need to process what the film capture with chemicals or use software to make from those zeros and ones from the sensor a photo. Do what needs ...

Photography or Graphic Art?
I suppose I am trying to communicate (and celebrate) the only view of reality I can. I am not trying to play God with the results. The results are what the camera saw, usually not what I saw, and they are what they are. But what the camera saw isn't reality then for you since you saw something else ...
