This is more of a technical/experimental post, and I'd like to get viewers' opinions of the resultant image quality and technique.
I've seen more and more people experimenting with digital infrared (IR) photography, so I've be curious to try it myself. Looking at the Digital Infrared group here on flickr, one person mentioned using a long exposure with an IR filter on an unmodified digital SLR. I knew my XTi had an IR blocker over the sensor, so I wasn't sure how this would turn out. I was pleasantly surprised to see the results be close to what seems to be near-IR photography, perhaps not true IR. Especially after running the RAW shot thru Photoshop with an IR b&w layer, it looks similar to what I've seen film IR shots look like.
Your thoughts? What are some of the ways these shots differ from IR or near-IR shots done on IR film or modified/IR-sensitive digital cameras?
Photos, top to bottom, left to right:
* color RAW "infrared" exposure
* b&w (with red "filter") in-camera JPG of the RAW shot
* RAW shot with Photoshop infrared b&w layer, red channel at -20 instead of -40
Technical information:
* Canon Digital Rebel XTi/400D (unmodified)
* Canon EF 28mm/2.8 lens
* Opteka Infrared filter (I think it corresponds to an R72 filter)
* late afternoon (approx 5:30pm) light in late Summer
* manual exposure: 30s at f/4, ISO 100
Just messing around with portrait lighting. Thanks to my daughters - Ellen modeling, Caroline assisting.
Gelled SB-28 behind model. SB-600 with a short snoot up and behind model on right. DIY 28" soft box aiming down a bit camera right.
30"x40" white foam core reflector camera left.
A 30"x 40" black foam core panel helped block spill from the soft box onto the background. This was hand-held.
If I had been more serious about the shot, I could have dialed things in better, but C&C is welcome, if you have it.
Kaleidoscope image taken with phone & not edited at all. Used Flickr uploading without a 3rd party app to search for and upload 2 of my phone images.

Ok for some reason the background is a weird color. I didn't change the wb or anything. Some of the pictures I took tonight were ok and some had a reddish tint to the background.

My next RC plane will be the Pulse 125. A recommended modification is the addition of a second pushrod (joined to the first) so that both elevators are controlled. This is sample test with some coathanger wire, thin copper wire harvested from speaker cable, and a 30W soldering iron with rosin core solder... and PLENTY of flux.
Testing focus at f32 to compensate for any errors. I'm really impressed with how sharp the Fujinon 125mm lens is! It seems to have a lot more contrast and sharpness than any other lens that I have used before. Time to try it out on proper film now.

Test of Yongnuo RF-603 from 2 city blocks away. The VAL (Voice Activated Lightstand) is firing the camera which is in turn firing the flashes.
Just confirming that my new 2024 Subaru Crosstrek Sport will fit. The other half of this old two-car garage is deeper and will fit a larger vehicle.
This is a test cake for my nephew's Carousel Cake at the end of the month. Need to make the round part of the cake double in height, so that I can fit some carousel horses. But other than that...it was easy to make!! :D
Using my Weston meter on a gray card. If you look back in this set you will see the day I loaded the infrared film into the F3 (not shown - that's a Nikkormat). It took a while to get to this - my life is full of distractions.
15TH APRIL, LONDON- Martin Thompson @mjpt777 explores when to start performance testing, how to avoid the common pitfalls, how to profile when the results cause your team to pull a funny face, and what you can do about that funny face.

What the heck?
I'll tell ya what the heck:
Test prints are an integral and often surprisingly beautiful and playful part of the hand printed process. They are never ever the same, and therefore true, one-of-a-kind, individual Monoprints. Made from varied layers and layers of inks from different print runs to check colors, clean out a messy screen and a dozen other reasons, Test Prints are spontaneously created and basically, magical. Hence once a test print is sold, that's it, gone baby.
I keep a few with me in the studio while printing and every now and then one looks suddenly nice & done. Like this one!
Visual field or perimetry test of my right eye. Due to glaucoma I have a slight defect in my vision. Luckily I have been treated early so the damage is slight and hardly noticable.
