You’ve seen it. That massive, deep-orange orb hanging right over the horizon during a summer sunset. It looks gigantic, almost close enough to touch. Naturally, you pull out your phone, snap a picture, and check the screen. What do you see? A pathetic, blurry white speck that looks more like a dirty pixel than a star.
Capturing decent images of the sun from earth is actually one of the hardest things for a casual photographer to pull off. It’s a literal ball of plasma 93 million miles away. It’s also incredibly bright—enough to fry your eyes and your camera’s sensor if you aren't careful.
Most people don't realize that the "size" of the sun in your vision is a bit of a psychological trick. It only takes up about half a degree of the sky. To get the kind of detail where you can see sunspots or solar flares, you need more than just a steady hand; you need a specific set of tools and a lot of patience.
The Problem With Atmospheric Disturbance
Earth’s atmosphere is basically a thick, wavy soup of gases. When light travels through it, it bends. This is what astronomers call "seeing." If the air is turbulent—which it almost always is during the day because the sun is heating the ground—your images will look wavy.
Professional solar photographers, like Andrew McCarthy (who is famous for his insanely detailed backyard shots), often use a technique called "lucky imaging." Instead of taking one photo, they record thousands of frames of high-speed video. Software then analyzes every single frame, picks the sharpest ones where the atmosphere happened to be still for a split second, and stacks them together. It’s the only way to beat the blur.

Honestly, the ground you're standing on is your biggest enemy. Asphalt radiates heat, creating those "heat waves" you see on a road. If you’re trying to take images of the sun from earth from a parking lot, you’ve already lost. Grass or water is better. They don't get as hot, which keeps the air above them a bit more stable.
Filters are not optional
Never, ever point a standard telescope or a long zoom lens at the sun without a dedicated solar filter. You will go blind. Quickly.
There are two main ways to see the sun. White light filters are the most common. These are basically sheets of specialized Mylar or glass that block 99.999% of the light. They show the sun as a white or yellowish disk, and they're great for seeing sunspots. If you want to see the "texture" of the sun—those boiling cells of plasma called granulation—you need a Hydrogen-Alpha (H-alpha) filter.
These filters are expensive. They only let through a very specific wavelength of red light ($656.28$ nanometers). This allows you to see the chromosphere, where all the dramatic action happens, like solar prominences leaping off the edge of the sun.

The Gear Reality Check
You don't need a NASA budget, but you can't do it with a smartphone alone.
If you're using a DSLR or mirrorless camera, a 400mm lens is the bare minimum to make the sun look like more than a dot. Even then, it’s small in the frame. A dedicated solar telescope, like those made by Lunt Solar Systems or Coronado, is the gold standard. These are built from the ground up just to look at one thing.
- Solar Film: Cheap, effective, and fits over your existing lens.
- Tracking Mount: The earth rotates. The sun moves across the sky surprisingly fast when you're zoomed in. A motorized mount keeps it centered.
- Mono Cameras: Many pros use monochrome (black and white) cameras. Why? Because color sensors use a Bayer filter that actually wastes some of the precious light data coming through those narrow H-alpha filters. You can always add the "orange" color back in during editing.
Why Do Sunsets Look Different?
At sunset, the light has to travel through a much larger chunk of the atmosphere. This scatters the blue light and leaves the reds and oranges. It also dims the sun enough that your camera doesn't immediately blow out the highlights.
This is the only time most people get "cool" images of the sun from earth. But even then, the sun often looks "squished." That’s atmospheric refraction. The air is actually acting like a lens, bending the light from the bottom of the sun more than the top. It’s an optical illusion, but a real one that shows up in your photos.

The Solar Minimum vs. Solar Maximum
The sun follows an 11-year cycle. Sometimes it's "quiet" (Solar Minimum), and you won't see a single sunspot for weeks. Right now, we are heading toward a Solar Maximum. This is the best time in over a decade to be taking photos. The sun is currently covered in spots, and massive X-class flares are popping off regularly.
If you see a "sunspot" in your photo and you aren't using a filter, it’s probably just a piece of dust on your lens. Real sunspots require magnification to distinguish them from sensor grime.
Practical Steps for Your First Real Shot
Stop trying to take a photo of the sun at noon with your bare phone. It won't work and it's boring.
If you want to get serious about images of the sun from earth, start with a "Solar Snap" kit or a sheet of ISO-certified solar film. You can rubber-band the film over your phone lens (carefully!) to at least get a clear, filtered shot of the disk.
- Check the Space Weather: Use sites like SpaceWeather.com to see if there are any big sunspots today. Don't waste time if the sun is blank.
- Focus is Hard: Autofocus will fail. You have to use manual focus. Zoom in on the edge of the sun on your screen and tweak it until that edge is as sharp as a knife.
- Fast Shutter Speed: Even with a filter, the sun is bright. Keep your ISO low (100) and your shutter speed high to avoid blurring from vibrations.
- Post-Processing: Use software like PIPP (Planetary Imaging Pre-Processor) and Autostakkert! to handle the stacking. These are free tools used by the community to turn shaky video into professional-grade stills.
The sun is a dynamic, violent star. It changes every hour. While the Hubble or the Parker Solar Probe get the "best" views, there is something deeply rewarding about capturing the same features from your own backyard. It reminds you that we're just clinging to a rock orbiting a massive nuclear furnace.
To take your next step, look into a "white light" solar filter for your specific camera lens diameter. Ensure it is ISO 12312-2 compliant to protect your equipment and your eyes. Practice focusing on the moon at night first; it’s the same relative size and much easier on the eyes while you're learning the ropes of long-focal-length photography. once you've mastered the moon, the sun is just a filter-swap away.
