    Hey all I'm also new to IR photography

    I have a Hoya Filter but what would you say is the main things to study on as the first photograph i took came out black so i guess i need longer exposure, And do you think there is anything else i need to concentrate on ?

    Thanks All

    What settings did you use for that first shot? Exposure time, etc.

    Well firstly you need a longer expsure, try about 8 seconds and exposure to compensate, the reason is that most sensors have an IR filter coating on them (ie a coating to block IR) to get round this you need a longer expsure to let the IR get through. This makes IR restrictive using a R72 filter becasue you are reliant on calm windless days.

    But it can be done and if you check through the IR thread you should see some results, just search for R72
