These are from the first infrared photography session I ever did. The camera is a full spectrum modified Canon T5i. I used a 720nm filter. I could not see through the viewfinder, not surprising since it is infrared, but the autofocus worked. After several test shots I settled on ISO 800 and 1/500 second exposure. Then guessed where I was aiming. I can see this being fun. In the not too distant future I will get filters for ultraviolet. From what I can tell, you can spend hundreds of dollars on a UV pass filter or $40 on one that lets some IR through too and an IR cut filter. I’ll try the latter first.
