About Me

Having a background in Photographic Science, Photo Retail and Camera Repairs plus a keen interest in landscape photography has drawn me to Infra Red Photography, however the outrageous prices being charged to convert digital SLR's and Mirrorless cameras to either Full Spectrum or Pure Infra Red led me to investigate how to convert my own camera. I started with a Sony Nex 5 because it can accept almost any lens ever made via the use of lens adaptors plus I have been using Sony A7, A7II and most recently A7rII as my main cameras for a year or two.

Basically to convert a digital camera to Full Spectrum involves removing the UV/IR Cut Filter [ Hot Mirror ] that covers the CMOS sensor, this allows all wavelengths of light to hit the sensor. However with no filtration the image will be very soft as no lens can focus UV, Visible and Infra Red light to the same point, but by simply adding a blocking filter to the front of the lens in use will allow photos to be taken in whatever type of light is desired.


The photo at the top of the page is taken with a Hoya R72 IR Filter, with the result converted to Black and White, giving the look of being taken on a cold crisp frosty morning, when in fact it was a dreary wet day in January when you normally wouldn't bother taking out your camera!!

I have since done several cameras for myself, and have started to offer already converted cameras on Ebay at much more sensible prices than available elsewhere. See;


The process of removing the UV/IR Cut Filter is basically to strip down the whole camera to remove the sensor, then remove the built in filter, then either replace that filter with another specific filter or have no filter at all for Full Spectrum usage. All cameras will then require the back focus distance recalibrating, before reassembly, this can be done on some cameras by changing the spacers the manufacturer built the camera with or adjusting spring loaded screws. This is the tricky part as the camera is in bits and does not work at all at this point, so you can't just turn a few screws until the image is sharp. Precise measurements of the thickness of the removed filter and the replacement filter [if any] have to taken and the new back focus calculated accordingly. If this is not done correctly the camera may not focus to infinity or even not focus at all.
All in all I have found that mirrorless cameras with permanent live view are by far the best candidates for conversion, and because they all have autofocussing systems based on the sensor rather than complicated mirror systems, the autofocus accuracy is maintained irrespective of the light used, UV, Visible or IR.

Full Spectrum Camera or IR Converted Camera - Which is Best and Why?

Full Spectrum Converted Cameras don't commit the camera to sole IR or UV usage as there is no permanent filter in the camera. You can therefore choose UV, IR or even back to visible by changing the filter on the front of the lens [See Below]. However you have to buy filters for each lens you wish to use, which could mean a variety of sizes and spectral responses, not to mention some lenses are very hard if not impossible to fit front filters, EG. Fisheye lenses 

IR Converted Camera on the other hand have a pre chosen filter installed directly in front of the sensor, this is great as it allows any lens to be fitted and it will not need any further filtration to function. However the camera will only work with the spectral response of the fitted filter, nothing further can be done except another longer wavelength filter can be added to the front of the lens. So if a 590nm Gold effect filter were installed, a 720nm or 850nm could be added to the lens and it would be as though the 590nm were not there, except for about a 1 stop exposure increase. You could not however go the other way, the 590nm fitted filter would block nearly all visible and UV light, no extra filter could ever get that back.

So which is best, my personal choice is Full Spectrum as it gives many more options, but if I had several lenses with different filter sizes or unfilterable lenses I would go for a 590nm internal filter. I personally don't have a Fisheye lens anymore, I used it a few times when I got it, but tired of the effect and my other lenses can use step rings if required, to adapt my filters.

Are Full Spectrum Cameras sharper than before conversion? Yes, but only very slightly due to a thinner sensor stack. 

Recommended Filtration

All the Full Spectrum Converted Cameras will require some filter added to the front of the lens in use, but which filter to use?

Deep Red Filter such as Hoya R25A
- Easliy available sometimes very cheap secondhand, gives very good False Colour Effects, but does require some Photoshop Processing Skills. The RED and BLUE Channels have to be swapped in Photoshop, NB. NOT PHOTSHOP ELEMENTS!! See The Tutorials Page for full details. Also good for Black and White shots with minimal post processing.

The R25A filter is very similar to a 590nm internally fitted filter and has virtually identical results.

720nm IR Filter - Such as Hoya R720 - Not as good for False Colour but Excellent for Black and White. Doesn't require much post processing and results look fantastic in Black and White without being over the top. Foliage looks frosty, blus skies very dark, but not Black. overall my Favourite, although I do like the Gold Effect ocasionally. Not quite as contrasty for B&W as 850nm filter, but 1-2 stops better in exposure.

An internally fitted 720nm filter has almost identical results to an external R72 filter

UV/IR Cut Filter - Such as Hoya UV&IR CUT
  Takes the converted camera to normal Visible Light Sensitivity albeit with a Custom White Balance, the Auto White balance is unlikely to work as well as with the original internal filter. The other problem is when the UV/IR Cut filter fitted to the front of wide angle lenses its effect is reduced towards the edges of the frame, giving slightly discoloured corners. So not ideal, a Full Spectrum Camera will never be quite as good colour quality as before conversion.
