erl Posted March 31, 2007 Share #1 Posted March 31, 2007 Advertisement (gone after registration) Walkingmy dog Merlin on the beach today, I flung off some pics against the light. 4pm Autumn (Fall) clear sky and a receding tide gave the relaxed elements to blaze away, which I did. The attached pic & 100% crop showing detail amazes me. Settings were f5.6 on Auto which gave 1/8000 sec., ISO160. IR cut filter and image processed in C1Pro, film setting @ Linear Profile. No sharpening applied, but slight tweaking of levels was made. Image is virtually BW because of the lighting, but developed from DNG to give colour jpegs for this forum. In the original, detail is clearly percievable in the my dogs coat on the shadow side. I also find the quality of various areas of the water to be superbly reproduced. Specular highlights are nice and crisp. Summary: I reckon the M8 with a good lens is a formidable tool. If weather permits, I just may repeat the process with my M7 tomorrow, just to convince myself to keep it!

lct Posted March 31, 2007 Share #2 Posted March 31, 2007 ...Waddya reckon? Hi Erl, nice pic as usual. Is it me or is there some magenta cast here? Link to post Share on other sites More sharing options...
stunsworth Posted March 31, 2007 Share #3 Posted March 31, 2007 LCT, I think it'll be chromatic abberation rather than an IR problem - I've had that quite a bit in similar lighting situations both with and without an IR cut filter. Link to post Share on other sites More sharing options...
lct Posted March 31, 2007 Share #4 Posted March 31, 2007 Would've expected CA in more contrasty parts of the picture but i may be wrong. Link to post Share on other sites More sharing options...
erl Posted March 31, 2007 Author Share #5 Posted March 31, 2007 Hi LCT, That phenomena occured in a number frames today. At first, I thought it was magenta, but by varying the the screen magnification it dissapeared at certain multiples. I'm no techy, but I think it is an artifact of screen repro. In the C1 screen, when magnifying, I could see what I think were individual pixels in tri-colour. NOT magenta. I don't for a moment think it is IR. It's late here. Will try to find time tommorow to crop that area to illustrate the case. G'night all. Link to post Share on other sites More sharing options...
