Here's a breakdown of the process, considerations, and alternatives, keeping black and white landscape in mind:
1. Understanding the Conversion Options:
* Full Spectrum Conversion: This removes the hot mirror completely and replaces it with a clear glass filter. The sensor becomes sensitive to ultraviolet (UV), visible light, and infrared light. This is the most versatile conversion. To take B&W IR photos, you'd then attach an IR filter (like a 720nm or 850nm) to the lens. This allows you to experiment with different IR wavelengths.
* Dedicated IR Conversion: This replaces the hot mirror with an IR-passing filter directly. This filter blocks most visible light, allowing primarily IR light to reach the sensor. You'd typically choose a specific wavelength like 720nm, 850nm, or 590nm (though 590nm isn't ideal for strong B&W IR). This is simpler since you don't need an external filter for IR photography, but it's less flexible as it's "locked" to that specific IR wavelength.
* Why B&W Landscapes Matters: For B&W landscapes, a full spectrum conversion offers the most flexibility. You can experiment with different IR filters to achieve various levels of contrast and tonality in your images. A dedicated IR conversion is fine if you know exactly the "look" you're after, but less forgiving if you change your mind later.
2. Deciding Whether to DIY or Hire a Professional:
* DIY Conversion: Requires significant technical skills, patience, and a clean, dust-free environment. The process is highly delicate. You risk damaging the sensor. If you're comfortable disassembling electronics, have the correct tools (ESD safe environment, screw drivers, tweezers etc.) and have watched tutorials it may be possible for you.
* Professional Conversion: Safer and generally recommended. Companies like LifePixel, Kolari Vision, and Spencer's Camera offer conversion services. They have specialized equipment, experience, and warranties. Contact them for pricing and available options.
* Benefits of a Professional:
* Avoid damaging your camera.
* Guaranteed results.
* Sensor cleaning and calibration are included.
* Option to have a protective coating applied to the sensor.
3. Choosing a Camera Body:
* Consider a Used Camera: Infrared conversion makes the camera essentially dedicated to IR photography (or requires using external filters for visible light). Converting a primary camera is usually not recommended. Purchase a used camera specifically for IR conversion.
* Sensor Size: APS-C sensors are generally a good compromise between price and image quality. Full-frame sensors offer wider dynamic range and potentially better low-light performance, but the conversion will be more expensive.
* Live View is Crucial: You'll need live view to compose and focus. IR light focuses differently than visible light, so the viewfinder will be useless. Some companies calibrate your lens to your camera for IR photography after conversion.
* Compatibility: Ensure your lenses are compatible with the chosen camera body.
* Mirrorless vs. DSLR: Mirrorless cameras are often preferred for IR because you can "see" the IR image through the electronic viewfinder (EVF) or LCD in live view, which makes focusing easier. DSLRs can be used, but focusing is more challenging due to the optical viewfinder and the need to rely on live view.
4. The Basic DIY Conversion Process (Simplified - For informational purposes ONLY. DO NOT attempt without thorough research and experience):
* Preparation:
* Gather all necessary tools: small screwdrivers, anti-static wrist strap, compressed air, lens cleaning supplies, magnifying glass, spudger tools for removing components and a camera repair toolkit.
* Work in a clean, dust-free environment.
* Discharge any static electricity by grounding yourself.
* Print out detailed disassembly instructions for your specific camera model (available on iFixit, YouTube, or similar resources).
* Take photos or videos as you disassemble, documenting each step.
* Disassembly:
* Carefully remove the camera's outer casing.
* Disconnect ribbon cables and wires. Be extremely gentle!
* Locate the sensor assembly.
* Remove the sensor assembly.
* Hot Mirror Removal:
* The hot mirror (IR cut filter) is usually glued or attached with small screws.
* Gently remove the hot mirror. This is the trickiest part. Some heat may be required (use a heat gun on a low setting).
* Filter Installation:
* Clean the sensor thoroughly with sensor cleaning swabs and solution.
* Install the new filter (clear glass or IR-passing) in place of the hot mirror. Ensure it is perfectly clean and aligned.
* Reassembly:
* Carefully reassemble the camera in reverse order.
* Double-check all connections.
* Testing and Calibration:
* Test the camera to see if the IR light is making it to the sensor.
* Use trial and error or focus peaking to calibrate your lens for the differences in focus distance with IR light.
* Take test shots to check image quality and focusing.
5. Equipment for Infrared Black and White Landscape Photography:
* Converted Camera: With either full spectrum or dedicated IR conversion (full spectrum is recommended for flexibility).
* IR Filters (for Full Spectrum):
* 720nm Filter: A good starting point. Produces strong IR effects (white foliage, dark skies) with some visible light still getting through.
* 850nm Filter: Blocks almost all visible light. Creates a more extreme IR effect.
* Experiment to find your preferred look.
* Lenses:
* Wide-angle lenses are excellent for landscapes.
* Lenses with good contrast work well in IR.
* Some lenses exhibit "hot spots" (bright center) in IR photography. Research your lens compatibility before using it.
* Tripod: Essential for sharp images, especially in low light or with longer exposures.
* Remote Shutter Release: Minimizes camera shake.
* Light Meter (optional): Useful for accurately measuring IR light, though you can often rely on your camera's metering. You will need to experiment to get the right exposure.
* Image Editing Software: Photoshop, Lightroom, or GIMP are used for post-processing.
* Dust blower/Sensor cleaning kit
6. Shooting Tips for IR Black and White Landscapes:
* Shoot in RAW format: Provides maximum flexibility for post-processing.
* Sunny Days: IR photography works best in bright sunlight.
* Compose Carefully: Look for elements that reflect IR light well (foliage, clouds).
* Focus Accurately: Use live view and manual focus.
* Experiment with Aperture: Stopping down the aperture (higher f-number) can improve sharpness.
* Experiment with Exposure: IR light is invisible, so you may need to adjust your exposure settings.
* Check Your Histogram: Avoid clipping highlights or shadows.
* Use Lens Hoods: Prevents Flare
7. Post-Processing:
* Convert to Black and White: If you shot in color with a full-spectrum camera, convert the image to black and white in your editing software.
* Adjust Contrast: Increase contrast for a dramatic IR look.
* Adjust Tones: Fine-tune highlights, shadows, and midtones to achieve the desired tonality.
* Dodge and Burn: Local adjustments to selectively lighten or darken areas.
* Sharpening: Sharpen the image for added detail.
Alternatives to Full Camera Conversion:
* Screw-on IR Filters (for Existing Camera): You can use a strong IR filter on the front of your lens. The downside is that you'll need very long exposures and it can be difficult to see through the viewfinder. It will also limit you to IR photography while the filter is attached.
* Infrared Film: A traditional approach. Requires a film camera and darkroom skills. Offers a unique aesthetic.
* Digital Infrared Filters: Many photo editing programs have IR filters that you can apply digitally.
Conclusion:
Converting a camera for infrared black and white landscape photography is a rewarding but involved process. Consider your budget, technical skills, and desired level of flexibility before deciding to DIY or hire a professional. Full spectrum conversion offers the most versatility. Experimentation is key to mastering IR photography and achieving your artistic vision.
