Newbie question re IR-cut filters

[dibyendumajumdar]

I had my Z6 modified to remove the IR filter on the sensor so that I could use it for astro photography.

The camera has become unusable for general photography after the change, so I was wondering if there is way around such as adding an IR-UV filter on front of the lens. I just bought such a filter but it seems to have no effect?

Any tips gratefully received.

Thanks

I'm using BG-40 on my modified Z5/Z6 for the occasions I also need to take "ordinary" shots.

This works quite well, but in order to get best accuracy of colour renditon, you ought to make specific profile via Colorchecker Passport or similar.

Thank you - any particular make recommended? I think I need a 52mm size filter to start with.

Looking at the work done, I see that a 720 NM filter was put in front of the sensor; my understanding is that this blocks visible light ... and that's why no matter what I put on the lens, its the same light spectrum.

My bad that I didn't clearly understand what was done.

Presumably I can use this camera mostly for IR B&W photography now.
