Richard Vanek - Black and White Photography

I have updated last roll page again. This time for long time promised effect on Nikon D70 digital. I put five pictures which represents some things I encounter while using D70 for few hours. One I can't explain others are just difference from analog I am use to. Well take a look and if you know answer to my question from first two picture, please let me know.

This is a strange effect I have found when exposing into sun through the edge of leaf (1/1500 s, F 4.80, focal length: 52.00 mm). I have no idea what that light green blue net of pixels is. hwy it is there and what fault it is. It is because CCD? If you have clue, please please let me know, I am really curious. I am quite often taking shots into difficult light. I would hate to see this every time.

Update: This is what seems to me as reasonable and possibly correct answer:
"Think of the CCD elements as small buckets that fill with electrons during exposure. When the buckets are full, they spill over and the electrons run into adjacent buckets.
Another thing that happens is that, when one channel (RGB) blows out (buckets fill), before the other channels, software interpolates what the color at that location should have been. But that is based on a guestimate at best. I think this is what caused the cross hatched effect in the border of the blow out region"

But there is still interesting that just next pixels are almost dark. It is kind of net. That what you see on enlarged version is 1:1 pixel magnification from raw file. Effect appears only on top and bottom of highlighted area from Sun, not on side.
There is also some possibility that it is cost by electronic shutter of D70 (I have no idea how that kind of shutter works).

I did shot in a attempt to see how sensor will handle direct sun into it. Lens wasn't any expensive just simple AF 28-80G/3.5-5,6, but was very good for shots I did in this sunny afternoon. (1/1500 s, F 4.80, focal length: 52.00 mm ) As you can see there are beams of light coming from place where Sun was just about be uncovered by leaf. I like this effect. What I do not like is strange effect you can maybe see as well. These are light green blue parts on top and bottom of bright area. In zoom it looks like net of dark green blue and light green blue pixels. What it is? I have no idea but it is very distracting.

I was after that light effect which you will get when you shoot on film very reflective surface. I made this shot also on film. I was wondering if I get same effect as on film with stripes of light rendering outside reflected surface. As you can see here tehre is no such a effect on the bel of bike. It is competely overexposed (as expected) but no artifact outside of reflection area. Pity I like that effect of film in this situation.

This is shot on the same place but now with about -2EV exposure compensation (1/250 s, F 3.30). As you can see part in dark shadow (inside) is quite dark as it should be. The outside is possible to see details on concrete stones in bright sun. I guess this is just normal handling of difficult light. So it is up to the photographer.

This was just test of light metering. I was using aperture priority and made shot where more than half of frame was in dark shadow and about 1/3 in direct sunlight. (1/45 s, F 3.30) As you can see part which was outside is completely burned. There is no information on concrete tails about any structure. I didn't make this test with film camera, but I must say I was hoping in Nikon 3D exposure metering. Well here it's failed. I guess it was trying to make dark looks like zone V and therefore outside just jump out of dynamic range.
