    I think there are filters made specifically for that.

    I used shade 10 welding glass to photograph the transit of Venus.

    Not good. NASA recommends #14 welding glass only. Apparently it has a thin metal coating on the glass that is recommended for all sun viewing.

    It may have been a shade 14 now that I think about it. It was a while ago, I don't remember haha.

    Might want to check. I would hate to see anyone end up with eye damage or blindness.

    Yup, it was shade 14. Good thing I had a video when that picture was presented on our local news channel. I guess I was smart enough then. Lol

    Baader makes a nice solar film

    But you have to understand what for initially ==> Differences in AstroSolar® Solar Films - AstroSolar.com

    then, dependent upon your location,
    search for someone that makes either the film for a film holder like Cokin
    or a screw in filter, or a generic assembly.

    There are different types of solar filters.
    What features, if any, on the Sun do you want to photograph?
    Or do you just want a white circle that has no detail?
    For the Sun to have much in the way of scale in the frame you'll need quite a bit of magnification.

    The least expensive filters will let you see/photograph sun spots.
    You can make a DIY filter for your camera lens using a small sheet of solar filter material like the Baader film or like this:
    4"x4" Solar Filter Sheet for Telescopes, Binoculars and Cameras
    Or you can use a small telescope with a solar filter on it if you want the sun to have more scale in the image frame.

    If you want to see/photograph solar granulation and/or prominences you'll need to use a hydrogen alpha filter.
    At the low end small 40 mm, f/10 solar telescopes with an internal non-removable 1.0 angstrom hydrogen-alpha (Ha) bandpass filter start at about $630:
    Meade Instruments Personal Solar Telescope

    You can step up a bit to the same telescope with a 0.5 angstrom hydrogen-alpha (Ha) bandpass for $1200:
    Meade Instruments 0.5PST Coronado H-Alpha Personal Solar Telescope (Black)

    From there the cost of solar telescopes goes up pretty fast as the objective lens gets larger.
    90 mm f/8 or so solar telescopes with 0.5 angstroms of bandpass are in the $5000 range.

    To look at sunspots I use an 80 mm f/5 regular telescope. I put a
    Orion 7785 4.00-Inch ID E-Series Safety Film Solar Filter on the telescope. With that filter I can't see prominences nor granulation detail.

    Yup, it is real camera. That is one serious piece of equipment for astro photography.
