IR with D300

[sandeep_vengsarkar]

has anyone tried shooting with IR filters on a D300?

read the posting about D200 which was a No No.

How does the d300 fare.

i understand that heliopan has 2 versions of IR filters but what are their individual strengths is a mystery.

Any suggestions

I don´t know how it compares to D200 but compared to a D70 is about 3 stops slower (3 times more intense hot

mirror). You should expect about 5 sec at ISO 200 at daylight.

 

I suppose this is not an issue since you would be using a tripod eitherway.

 

There is an alternative method instead of filters and that is using exposed film in front of the lens.

Just from my experience, exposed film gives equally good results most of the times and it also has greater

transmission than a dedicated filter, though the cutoff is closer to the visible spectrum.

 

Check the samples here:

(Have in mind that the shots were consecutive taken with a D70 with custom WB presets for both methods and that

for the exposed film version the exposure time was about half the dedicated filter one).

I suppose the second one is sharper because of the higher cutoff of the filter (nearer visible spectrum).

D300 without modifications works very poorly for IR.

D300 even with modification works poorly for IR.
