Probably about the same look as you'd get with a non modified camera since little HII is involved. This should encourage others with DSLR's to piggy back their cameras! In any case that's a great image. I took a shot in the early 60's (1961?) of it using a 400mm f/6.3 lens that cost me all of $35 and an Exa body that cost the same. Though instead of a real mount I used a two hinge barn door mount driven by a 30's era wind up alarm clock mechanism. I suppose that clock if not tore up for the drive would be worth a lot today. I have no idea what happened to either the barn door mount or the "drive". I used Tri X and 30 minutes. Today's CCD's have far more resolution than 35mm Tri-X. The attached photo is as big as it can go without severe grain showing and has all the resolution of the negative (lost when a tree limb came through the roof in 1991 during a severe ice storm). -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

Image reduced to 50% of original. Wow! Can I see the full size please? -- http://www.petersparrots.com http://www.insanevideoclips.com http://www.petersphotos.com After an enjoyable eighteen holes of golf, a man stopped in a bar for a beer before heading home. There he struck up a conversation with a ravishing young beauty. They had a couple of drinks, liked each other, and soon she invited him over to her apartment. For two hours they made mad, passionate love. On the way home, the man's conscience started bothering him something awful. He loved his wife and didn't want this unplanned indiscretion to ruin their relationship, so he decided the only thing to do was come clean. "Honey," he said when he got home, "I have a confession to make. After I played golf today, I stopped by the bar for a beer, met a beautiful woman, went back to her apartment and made love to her for two hours. I'm sorry, it won't ever happen again, and I hope you'll forgive me." His wife scowled at him and said, "Don't lie to me, you sorry scumbag! You played thirty-six holes, didn't you?" |
