the tilts all this way and that add to the confusion. Nice going. Penny Street

I thought the dots were sort of bokeh as there's light dots & dark dots. Are the dark sort of dots on the house dust spots? If they're they hardly affect a picy like this a.
Thanks Doug. I did some pinhole paper negatives that way back when. Thanks Brent, it remeinded me that I've never cleaned the sensor. A few puffs of air cleared out most of it (after this picy) but there's still some persistent dots which I suspect are going to be troublesome except with larger apertures than a pinhole. Rod, this is the one with the "grain" if you get a good monitor you will see clearly random dots. On subsequent images like the portrait, I cloned out the worst of them. It's probably about a 9.234 Mpxl sensor at this point. -tv

Great idea for this topic Tommy, well done mate. I didn't see the picy with the dust spots, when you use dust delete data does it map out & not use the pixels where the dust is? I was wondering if so you will end up with a 4 MP sensor if it was that dirty.
Cool idea Tommy. I expect most any camera would look like you sneezed all over the image given this test. I'm going to try this sometime for fun- after cleaning my sensor :-)

I thought the thick grain was nifty looking until I read where it was coming from. I remember doing pinhole photography in high school. We put a pinhole in the front of a box that had photo paper inside it that absorbed the light. The exposure took quite some time and was obviously black and white but the lessons we learned about the pinhole size vs exposure time would carry over into newer technology. -Doug
