We report here that polyethylene glycol PEG linked to near infrared dyes conjugated to chimeric mouse-human anti-carcinoembryonic antigen CEA antibody greatly improves imaging of liver metastases in a nude mouse model of colon-cancer experimental metastases. The dyes were initially injected intravenously into nude mice without tumors. Tissue biodistribution was determined by tissue sonication and analyzing tissue dye concentration profiles over time.
I haven't shot a lot of infrared in a couple of years partially because of what I've heard of the usability of the more recent Nikons using IR however I'm not one to allow what I call "Internet regurgitation". Used in a sentence: "I thought I could hammer a nail into my skull as long as it was through my ear but I guess that was just internet regurgitation since I'm dead now. One of the popular internet photography regurgitations is that "The doesn't work well with infrared filters.
I've recently been really interested in IR and think some of the images that you can get with IR is quite beautiful. I know the Canons can do IR and have seen many examples here on Photo. I used to do it with my D1 all the time.
In a basement in Manhattan, people are sweating. Yes, it does. But as the adage goes: I f it sounds too good to be true, it usually is exactly as good as it sounds, especially when you look closely at its nebulous claims.
Order as many items as you want for one low delivery fee per order to an address in Australia. Sometimes not all items in your order are available for shipment at the same time, and items may be delivered separately. If we need to do this there is no extra charge to you.
Greetings everyone! Much has been brewing, as you shall see from the items below. I truly hope you enjoy and find beauty in the photography I have to share this month.
One reader came to the conclusion that when shooting infrared that people in the images should be avoided, possibly because they looked horrible. Of course people can look quite nice in infrared and horrible if you wish depending upon the vision and execution of the photographer. So, to demonstrate that, I hired a model and created the following images using an infrared camera. All the images herein were created with a pre-conceived notion of what I wanted the images to look like, somewhat surreal and dreamlike but without going to extremes.

First of all, this experiment has a high probablility of damaging your webcam beyond repairso please use an old webcam and don't complain to us if it breaks. The sensor in a webcam is sensitive to both visible and infra red IR radiation so the manufacturer adds a filter to stop the IR, otherwise it would produce unexpected results when it took photos. So we want to remove this filter and replace it with one that stops visible light but allows IR through. As we have seen in another kitchen science, a remote control looks different in infra-red.
