Can Infrared Photography Be Done In Studio

by -151 views

One of the things I preach when teaching photography is the power of “dissimilar.” I urge my students to always exist on the lookout for ways to create photos that are different from what other people are doing. That’s the reason why, subsequently color photography became the norm, black-and-white suddenly became the “new” thing to exercise. It’south also the reason behind the minor resurgence in flick photography. Not that it’s better (it’s non), but considering it’due south unlike. And when it comes to unlike, infrared photography is about as different as it gets. (Note: this story isn’t a deep swoop into the technical side of infrared photography. You can discover lots of that elsewhere online. Here, I’ll tell you about my existent-world experiences using infrared.)

In normal photography, infrared light causes problems. That’southward because we tin’t run across it, and if cameras could, issues crop up with things like color, focus and exposure. That’south why all digital cameras today have a glass filter over their sensors, which, among other things, blocks infrared lite. Then if you want to try infrared photography, the first thing you lot take to do is defeat that filter. There are 2 ways to achieve that, each with advantages and disadvantages. Since the start is less expensive (an reward), that’s where I’ll start.

The Hoya R72 filter is similar using a heavy neutral density filter, blocking visible light and only letting infrared light pass.

While your camera is designed to prevent infrared light from interfering with photography, a minor corporeality of that light does become through. Withal, it’s not enough to cause whatsoever issues. But, if you add together a filter to your lens that blocks visible light and only lets infrared laissez passer (the Hoya R72 is a popular pick), the simply light your camera would record would be infrared. Which brings up the first problem (disadvantage) with using a filter – it’due south extremely dark. Because of that density, you demand a long exposure (measured in seconds) for enough infrared to become by that blocking filter within your camera to create an image. And, since the metering arrangement is also designed for visible light, you’ll find a proper exposure not through the meter, but through trial and error. In my experience, an overexposure of ane to 4 stops beyond what the meter says will get you close. That apparent overexposure will disappear when you process the prototype.

This is my original capture from a trip in 2007 using the Hoya R72 filter on my Nikon D700, at ISO 200, f/5.vi and 2.5-seconds. At that time I didn’t realize how much apparent overexposure was needed for a good infrared exposure, so this is actually pretty heavily underexposed. It should have been at to the lowest degree a 10-second exposure. Luckily, I was able to correct for that in processing.

After correcting for the white remainder in software, I then chose to requite the sand and sky a blue cast.

Working from a tripod (considering of the long exposure), and with a filter that’s very dark, y’all’ll need to compose and focus before putting the filter on your lens. Which brings up another disadvantage: your camera’due south focusing system is designed to work with visible light, not infrared. With a mirrored camera (DSLR), that means your focus can exist slightly off (whether using a filter on the lens or a converted camera). Since most IR photos are shot with wide-bending lenses, small apertures (similar f/eleven) and depth of field usually solve that problem. This isn’t an result with mirrorless cameras, since they focus off the sensor (which is accurate for both visible and IR lite). Newer mirrored cameras can often “meet” through that night filter when in Live View, which means you may be able to focus using the rear LCD, which is also using the sensor for focusing. If you do have a mirrored photographic camera converted, there’s frequently an option to send a lens in with information technology and have the camera calibrated to that lens, to solve the focus problem. Of grade, there’s an additional charge for that service.

The final disadvantage to using a filter on the lens is that you’ll exist more limited in how you can procedure the image. It’south great for black-and-white infrared, simply for the pop “false colour” images, it tends to be less effective (though this depends on the model of photographic camera being used, and how much IR it actually blocks). And that brings us to the more than expensive option, which is having a camera converted to infrared photography.

A archetype infrared black-and-white, using the Hoya R72 filter on the lens for the original capture, then converting to monochrome in software. In this case, the dumbo IR filter, requiring a long exposure, acted as an ND filter resulting in blurred h2o. Nikon D780, Manual exposure, ISO 200, threescore-seconds at f/10. Nikkor VR 16-35mm f/4G lens at 16mm.

An infrared conversion ways removing the IR blocking filter covering the sensor in your photographic camera. Of class, that besides takes abroad anything else that filter does, things similar UV filtration and low-pass defocusing (to preclude moire), and renders the automatic dust cleaning characteristic not-functional. At this point, there are two options. One, to supercede that filter with an IR passing filter, or two, supervene upon it with articulate glass. The advantage with either of these options is that your exposures are now similar to what yous’d have with a normal camera. With that infrared blocking filter gone, you lot’re now shooting at shutter speeds that don’t require a tripod. You can utilise the photographic camera’s autofocus arrangement easily (and very accurately with mirrorless or Live View on a mirrored camera). Finally, you tin can use the camera’southward metering system too, as long as y’all remember you lot’ll need to overexpose, just like when using a filter on the lens.

The least expensive of these two options would exist replacing the camera’south stock filter over the sensor with an IR passing filter, which unremarkably costs effectually $250-$300 (depending on the photographic camera model). While yous can relieve coin past doing that yourself, it’s also pretty like shooting fish in a barrel to ruin the photographic camera (Life Pixel has tutorials on doing information technology yourself. Take a look, they’re not for the faint of centre). Not being that brave, I’ve now sent three cameras to Life Pixel since 2007 to have them supercede that filter (there are other companies that do this also, but I’ve been very pleased with Life Pixel’s service). When having that filter replaced, you have multiple choices. Afterwards reading about the unlike ones and what they do, each time I chose the “Super Color” filter, as it would give me the most flexibility in how I process the photos afterwards. But remember, doing this makes that camera an IR photographic camera only – it tin no longer be used for “regular” photography (although y’all could pay again to have the process reversed later).

This is the first photographic camera I had converted to infrared back in 2007, a Nikon D70. I had Life Pixel supplant the congenital-in low-pass filter with a “Super Color” filter, meaning the camera could merely record infrared from so on. However, they did return the low-laissez passer filter with the camera in case I ever wanted to have it converted back for “normal” photography.

By 2022, I was using a Nikon D80 converted to infrared, again by Life Pixel, once again with a “Super Color” filter. This is i of the photos created with it, from outside Sedona. Note that I no longer need a tripod for daytime photography. Nikon D80, Manual exposure, ISO 100, 1/320 at f/8.

The tertiary camera I had converted, wanting more features and resolution than the D80, was a Nikon D7000. This photo is from February, 2022, when I took it forth on a workshop I was education in Republic of cuba. Nikon D7000, ISO 100, f/viii at 1/250, with Nikkor AF-S Nikkor 18-35mm f/3.v-4.5G ED lens at 24mm.

And one more photo from the Republic of cuba workshop, only this time I chose a black-and-white conversion of the infrared capture. Nikon D7000, ISO 200, 1/200 at f/11, Nikkor AF-S Nikkor 18-35mm f/iii.5-4.5G ED lens at 21mm.

The other option is to accept a conversion done that would let you use the photographic camera for dissimilar types of infrared photography, in addition to astrophotography and visible light (regular) photography. That choice is the most expensive, only gives you maximum flexibility. It’s chosen a “Full Spectrum” conversion, because now the photographic camera “sees,” and tin can record, visible, infrared and ultraviolet light. The procedure involves removing the manufactory filter covering the sensor and replacing it with what is essentially clear glass. With that done, you tin now add a filter to your lens for the type of photography you desire to practice (for astrophotography, no extra filter is necessary). While yous can shoot the camera without whatever filters, the results wait a fleck off due to the variety of wavelengths of light being captured. So in addition to paying for the conversion, yous’ll need to purchase the filters y’all desire, which is why this is the almost expensive of the options. And that’s just what I did for my about contempo IR conversion.

When Nikon introduced the Z 6 II terminal year I bought one, and so no longer really needed my original Z 6. But selling it used would only get me dorsum about half of what I paid for it. And I really, really like the camera, particularly for its depression noise performance at high ISOs. That’s when I decided to keep it, and instead send information technology in for a full spectrum conversion.

As I mentioned, I’ve had iii older cameras converted to infrared (all with the “Super Colour” filter installed). The downside each fourth dimension was that they didn’t accept all the features my newer cameras did, and were lower resolution. Only the conversion fabricated infrared photography easier than using a filter, and I had a lot of fun with each of them. Notwithstanding, information technology also meant that if I wanted to shoot infrared, I needed to bring forth an extra camera (and as DX cameras, I often needed to bring a super-wide DX zoom to get the focal lengths I prefer). Since I always travel with ii cameras, choosing to bring that infrared camera meant bringing a 3rd camera and extra lens, which wasn’t always possible. Even when information technology was possible, it meant I had to choose which bodies to carry when out shooting. For instance, on my Cuba workshops in early 2022 (pre-COVID, thankfully), I brought my infrared Nikon D7000, but each day would have to choose whether that would be my second camera or not – carrying three cameras was simply as well much. Having the Z vi converted to full spectrum not but solved that problem, it gave me other options too.

The scene around the filter is how daylight looks with a full spectrum conversion and no filter. The filter I’chiliad belongings is a “Visible Bandpass” filter, which blocks IR and UV to return proper colour to the scene. Nikon Z 6 converted to full spectrum, ISO 100, f/9 at one/200, Nikkor Z 14-24mm f/four lens at 15mm.

Calculation a “Visible Bandpass” filter to the lens returns the Z six to shooting every bit it did before, visible light photography. Putting a “Super Color” infrared filter on it lets me shoot the blazon of infrared I prefer. I also bought a “Hyper Color” filter, which is better suited for infrared black-and-white as well equally infrared portraits. And, without any filter, it’s an even better night photography camera than before (and it was fantabulous before!). So the Z 6 has now get the 2d camera I can take with me on trips. Changing filters changes what lite passes through the lens, and thus what kind of photography I can do with information technology.

My Nikon Z half dozen converted to full spectrum  and the 3 82mm filters I’m using with it. The Hyper Color (yellow) is for blackness-and-white and IR portraiture. The Visible Bandpass (blueish) lets me shoot the camera equally a “normal” camera. And the Super Color filter (blood-red) is for classic IR false color photography.

Are in that location drawbacks to a total spectrum conversion? Sure. Beginning, information technology’due south more than expensive. Then you lot accept to buy filters for what you desire to exercise (i at a minimum, but at to the lowest degree two to get the nearly out of this conversion). Yous have to carry and care for those filters. When using the Visible Bandpass to shoot “normal” photos, you lose well-nigh a half-stop of calorie-free due to its lite blue color. When buying those filters, yous need to get the size for the largest lens you normally use (for me that’due south 82mm, so I can’t use that Z vi with my long telephoto lenses). To apply those filters with small lenses, you lot need to buy footstep-up rings (about $15 each) for each of them and bring those along too. Despite all that, I believe the advantages in doing this will outweigh those disadvantages. I promise I’m right!

Daffodils at my local arboretum photographed with the full spectrum Z 6 and the Super Color filter. Nikon Z half-dozen, Aperture Priority, Preset white residue, ISO 200, 1/320 at f/11 in Matrix metering, +ane.0 EV, Nikkor Z 14-30mm f/4 Southward lens at 17mm.

This is how the original capture on i of my recent dark shoots looked right out of the camera with no filter, full spectrum only. I’chiliad using a pair of Lume Cubes to light the barn. Nikon Z six, IS0 2000, f/iv.5 at 8-seconds, Nikkor Z 14-30mm lens at 21mm.

And here’s that same image, after setting the white balance in Nikon Capture NX-D from a gray carte lit past the Lume Cubes. Nikon Z half dozen, ISO 2000, f/iv.five at 8-seconds, Nikkor Z 14-30mm lens at 21mm.

Before we get to the actual shooting of photos, in that location are ii more than things I should mention – flare and hot spots. IR is much more than susceptible to flare than normal photography, and then anytime the sun (or any bright light source, like the moon) is in front of you, you may get flare. Lens hoods are helpful, and I’ve also held my left manus out over the peak of the lens to stop, or minimize flare. Hot spots happen when using some lenses (it has to do with IR light and what it does inside the lens), and are more pronounced at small apertures. They’re just what they audio similar, a bright area in the center of the frame. In black-and-white, they can sometimes exist dealt with in software. With colour, though, they become much more challenging. I had hoped my Nikkor Z 24-200mm lens would exist a regular lens for IR, only information technology suffers from this. Fortunately, my Nikkor Z 14-30mm doesn’t, which is lucky for me because I shoot nigh IR with a broad lens, and I beloved that lens. After some testing, I’ve likewise plant that my Nikkor F-mount 24-120mm f/iv lens doesn’t show hot spots, and so I now accept a step-up ring to allow those 82mm filters to be used on it. You can find lists on the net where people take posted what lenses do and don’t piece of work for them, but those lists aren’t very comprehensive.

Here’south what you might see if the lens yous’re using (Nikkor Z 24-200mm f/four-6.3 in this case) is susceptible to hot spots. This doesn’t mean there’south anything wrong with the lens, but that it’s designed for working with visible lite, not infrared.

As for shooting infrared, here are a few tips.

– Sunlight is your friend. Information technology has lots of infrared, where overcast days don’t. Contrasty, mid-day calorie-free, which photographers ofttimes avoid, is actually great for infrared.

-Infrared is reflected and absorbed differently than visible light, which is one of the reasons it looks so dissimilar and why leafage can go white and skies blackness. Most artificial light sources lack infrared, although flash has a lot of it.

– Since the colour you see with your eyes is due to visible light, you lot need to think composition, not color.

– White residuum is nonetheless important, though, and the traditional way to offset is by creating a custom, or “Preset” white residue off a patch of sunlit greenish grass. Without that custom white balance, your unabridged image volition be red. If y’all shoot without a custom white balance in JPEG, you’ll be very limited in how you can process the prototype. However, if yous’ve shot in RAW format, it’s not a trouble, because then you tin gear up the white balance later the fact, in software. (Here’south more info about white residuum, and other topics like hot spots and lens flare.

– In normal photography, every bit long every bit you’re shut with exposure and white residuum, JPEG is fine. When shooting infrared, however, y’all’re working with low-cal that the camera’s not designed for, so you need the power that comes from having RAW data. With that, you lot at present have the power go much further when editing your infrared images.

But even with RAW data, there’s disagreement in the infrared customs over the best style to outset processing an infrared capture. Traditionally, that RAW image was all-time opened and initial white residuum set up using your manufacturer’s software, which is costless (I utilise Nikon’south Capture NX-D, but the newer NX Studio would work besides). This gives you more latitude in setting the white point and shifting colour than you lot’d go by going straight to Photoshop. Afterwards starting with the manufacturer software, you’d then open into Photoshop, or whatever your preferred editor is, to continue. This is my workflow. Some people believe you can create what’s essentially a profile, using Adobe software, that gets around the limitation that going straight to Photoshop would accept. I prefer the manufacturer software route, just of course, that’due south your determination to make, and but the first in many choices you take in editing your photos.

This is the original RAW paradigm shot with the Super Colour filter on my Nikon Z 6, equally viewed in Photo Mechanic, the browser I use. You can see by the EXIF information and histogram at correct that it would announced the image is desperately overexposed. But since it’southward infrared, that’due south not actually the case, every bit you’ll see in the next screenshots.

Opening that RAW image into Nikon’s gratuitous Capture NX-D (or I could use the newer NX Studio), I then ready the white residual using a preset that I had created before by photographing a gray carte du jour in sunlight with this filter.

At present opened in Photoshop, I use “Image – Motorcar Tone” to boost the contrast. That will assistance with any adjustments I may do later on.

In this case, I chose to practise a colour swap, where I used the Channel Mixer to swap the crimson and blue channels, resulting in this look.

Or, I could select “Image Adjustments – Black and White…” and adjust the color sliders to create an infrared monochrome image to my liking.

One of the fun things about infrared is that there’s no one “right” way to procedure them. Yes, a proficient white balance choice with RAW data is the correct starting time step, merely from there you tin can do whatever you want. As I mentioned before, contrast is your friend with infrared, so using Adobe Photoshop’s, “Image – Auto Tone,” can be a good second step. After that, for a traditional IR black and white image, try the “Image – Adjustments – Blackness and White…” tool, which lets you shift the tones based on the colors that are there. For a false colour “colour swap” image, employ “Image Adjustments – Channel Mixer…” starting with the Red channel and making Red 0 and Blue 100. So switch to the Blue channel and make Blue 0 and Red 100. Hue/Saturation is also great to play with, specially if you lot use the eyedroppers to target the exact colors you want to change. These are all adept starting points, although there are no rules here, and it seems there are an endless number of ways to procedure your infrared images. Non surprisingly, then, there are an countless number of YouTube tutorials on doing that. It’s really the wild, wild west when information technology comes to processing infrared.

Bridalveil Falls in Yosemite shot with my Nikon D80 and the Super Colour filter that was installed in it. This is another example of a archetype infrared capture converted to black-and-white. ISO 200, 1/60 at f/ten.

While I shoot most of my infrared images with a wide-angle lens, sometimes a telephoto is called for. In this instance, in the Palouse region of Washington, I used my Nikkor 70-300mm f/4.5-5.vi lens with the Super Color converted D7000. If I was closer to the field of study, I’d shoot a serial, bracketing focus, to recoup for the likely shift in focus caused by infrared. Just at this altitude, everything is at infinity. ISO 100, f/8 at one/320.

Here’s a koi (which is really merely a big orange carp) at the local arboretum, with some copse reflected in the water. But using my full spectrum Nikon Z six, and an infrared Super Color filter on the lens, information technology becomes something else entirely. Aperture Priority, Preset white balance, ISO 400, 1/320 at f/6.3 in Matrix metering, +1.0 EV, Nikkor Z 14-30mm f/four S lens at 25mm.

And then why did I start do an infrared conversion? For the aforementioned reason we often buy new camera gear – to practice something new with photography. And with the flexibility that this full spectrum conversion gives me, I await forwards to doing much more infrared than I have in the past. An added bonus comes when I do night photography, which is another “new” area I’ve been enjoying more and more over the last several years. With no filters attached, this converted camera volition give me even more adequacy after dark. Stay tuned, I’ll exist posting more photos to Instagram with my newly converted camera. Should exist fun!
