bill_derbyshire Posted February 26, 2012 Share Posted February 26, 2012 <p>Hi I love the look infared gives to stone and foliage. Always wanted to play with it.<br> I use a d-80 and know that there is an inherent IR filter over the sensor, my question has to do with the d70.<br> I thought i remembered that the d70 was better suited for possible infared as the ir filter was not as effective as later models. Any truth to that?<br> So, there it is any advise will be greatly appreciated<br> Bill</p> Link to comment Share on other sites More sharing options...
jyoungman Posted February 26, 2012 Share Posted February 26, 2012 <p>Yes, you can simply put a visible-light filter over the lens so that only the IR gets through. I tried this indoors without flash, and ended up with an exposure time in the tens of seconds (I guess at about f/8 to avoid problems caused by the fact that IR and visible light focus at different points with most lenses).</p> Link to comment Share on other sites More sharing options...
bms Posted February 26, 2012 Share Posted February 26, 2012 <p>You can achieve IR images with almost any digital camera, an IR filter (e.g. Hoya R72, B+W 092) and long exposure times. To my knowledge, having never used a D70, this works better with the D70 (or a Leica M8 which I have used), than newer models due to the weak IR filter. It should whoever noted that you only capture a small amount of light - the amount that passes both the IR filter and the "hot mirror" (IR blocking filter). To visualize, I found <a href="http://ir-photo.net/ir_imaging.html">this</a> helpful. It works but the question is how is the quality of the images....</p> <p>While you can probably get a D70 for a few $, the cameras are quite old and I would not trust them to last forever. IMO, most modern digital cameras with with live view are better suited for IR photography. The image in the LCD may be grainy, but you can focus and compose better. You can also leave the filter on the camera.</p> <p> </p> Link to comment Share on other sites More sharing options...
bill_derbyshire Posted February 26, 2012 Author Share Posted February 26, 2012 <p>thanks for your quick responses!<br> I will try the filter. Didnt think going back to the old d70, however cheap was a good idea.</p> Link to comment Share on other sites More sharing options...
bms Posted February 26, 2012 Share Posted February 26, 2012 <p>Here is a shot taken with the Leica M8 that was a very poor IR cut filter. Still exposure is 1.5 s at ISO 160 (I think f5.6 or so). I think you could expect similar results from the D70.</p><div></div> Link to comment Share on other sites More sharing options...
bms Posted February 26, 2012 Share Posted February 26, 2012 <p>As a comparison, the Nikon V1 performs rather poorly (most the light that gets though the filter is recorded by the red pixels and any post processing ruins the image pretty quickly). Exposure is similar....</p><div></div> Link to comment Share on other sites More sharing options...
jensvind Posted February 27, 2012 Share Posted February 27, 2012 <p>You could also convert the D70 into IR. Lifepixel.com do it.<br />Here is 3 photos 1. Original, 2. changed some colours, 3. BW. All in NX2 with NIK filters.</p><div></div> Link to comment Share on other sites More sharing options...

CvhKaar Posted February 27, 2012 Share Posted February 27, 2012 <p>If you are realy interested in IR Photography, then i think a SIGMA SD1 , SD14, or SD15 are the most usefull camera's, because they are converted to IR in seconds. This is because you can take the IR / UV filter out of the camera. This is designed this way for cleaning the sensor, so no permanent changes are done to the camera itself..<br> Al you need to do extra is put an IR pass filter in front of your lens, and you're on your way...<br> Sorry, this is not a Nikon solution, but you do not need to modify a DSLR this way..</p> Link to comment Share on other sites More sharing options...
bms Posted February 27, 2012 Share Posted February 27, 2012 <p>CPM, I did not know that. Found <a href="http://blog.sigmaphoto.com/2012/sigma-sd1-and-sd15-for-digital-infrared-photography-by-jack-howard/">this</a>. Interesting. Wish Nikons could be retrofitted that way, would save me from paying for UV/IR cut filters in front of the lens..... $214 for a 77mm...

arlon Posted February 28, 2012 Share Posted February 28, 2012 <p>Before I spent $277 for a filter, I'd buy a camera already converted off of ebay or simply find a cheap used d70 and have it converted. I used the Hoya filter for a brief time but the issues with slow shutters and focus adjustment (no AF) was just maddening. I had to use a tripod everywhere I went and then if there was a breeze everything was blurry. Then I had a used D70 converted which was perfect. I simply carried it to the park in a fanny pack and when something that I thought would look good in IR showed up I just swapped cameras and took the picture. AF was adjusted by lifepixel to IR, AF works perfectly and shutter speeds are normal.. The converted camera was just so much better. That camera was stolen on a trip to Tulsa OK and I replaced it with an already converted D100 I got pretty cheap on Ebay. I prefered the D70 but the D100 has been a fine camera for IR too. When my D800 arrives, I may have my D90 converted..</p> <p> </p> Link to comment Share on other sites More sharing options...
