Panoramas allow you to go wide, even if you don't have a wide-angle lens

     Panoramas are probably one of the oldest types of photos, dating back to daguerreotypes with sweeping views of cities.

    It is a format that's especially good for landscapes or if you're capturing something really large. Photographer David Bergman has done "gigapans" where he captures ultrahigh resolution panoramic shots where you can zoom in on individual details in the photos.

    There have been special cameras made for panoramas, including some that had rotating lenses that would cover multiple frames of film to capture the image. But a more common way to do it is to put multiple pictures together, which is how the originals were made.

    In this day, it is fairly easy to make panoramas regardless of what camera you use, especially with computers doing the stitching seamlessly.

    If you have a cellphone camera, you most likely have a pano feature built into the camera. All you have to do is press the shutter button and move the camera in the direction shown on screen to capture a panorama.

    The key to a successful one is to keep the camera steady, not jerking it around up or down, which will ruin the photo.

     If you have another type of camera, be it a point-and-shoot, bridge, mirrorless or DSLR, there are ways to create panoramas. It involves taking a series of pictures and then stitching them together in a computer.

    To get the best results, you want to shoot in portrait (vertical) orientation, as this will make assembling the panorama easier, as there will be fewer awkward edges that will have to be cropped out.

    You also want to lock your exposure to ensure the pictures have a uniform look, or the finished picture is going to look awkward, unless you spend extra time balancing out exposures in post. You should have some overlap, about 10-20 percent, to make it easier to join them and avoid any gaps.

    There are a few options for stitching them together.

    One way is a bit more artisanal. Basically open the pictures in your photo editor and line them up, doing some cropping and masking to eliminate seams.

    Some photo editors, such as Adobe Lightroom Classic, will automatically stitch the pictures together into a seamless panorama.

    There are also free software options that will stitch your photos together. One of the best is Hugin, which runs on both Windows and Mac, that lets you stitch traditional 180-degree and 360-degree panoramas.

Getting 360-degree panoramas with your cellphone with help from Google

    We've all seen those photos on Google Earth and Street View that show a 360-degree panorama of a subject.

    It gives you a chance to see an area as if you were actually there. When my wife and I were house-hunting after I had gone ahead for a job, we would use Street View to take virtual driving tours of neighborhoods where we were looking to buy, so we could both get a sense of the area.

    While Google uses a sophisticated camera mounted on a car, or backpack for trail views, and dedicated 360-degree cameras are in the triple digits, you can do it yourself inexpensively if you have a cellphone camera.

    If you use an Android (sorry, iPhone users), you can get a VPai Clip for your phone. The golf-ball-sized device, which I got online for less than $20, is not a camera as much as it is a pair of lenses for your cellphone. Each lens captures a 210-degree field of view.

    I know what you're thinking: That adds up to 420 degrees, and a full circle's only 360 degrees. Well, those additional 60 degrees allows the software you download on your phone to overlap and seamlessly stich the pictures together to create a 360-degree photo that you can see as a panorama, a sphere or a "little planet."

    If your phone's only capable of FHD video resolution, the image quality may not be the greatest and you'll have to upsize it to post it on Google Street view, but in the words of Krusty the Clown, it's not just good, it's good enough. Check out this one I did recently.

    But if you're using an iPhone, or don't want to get an attachment for your phone, Street View has you covered.

    The Google app has an option that allows you to use your camera's full resolution and optics to capture a photo sphere. It takes patience, a willingness to have people think you're a bit insane and a pair of steady hands.

    When you go to take a picture, the app will display a dot on the screen for you to line up on, and when you line up it takes the picture and moves the dot to the next spot. Eventually, you'll do a full 360-degree arc horizontally and vertically.

    If you do this, it's important to stay in one spot and turn in place, otherwise it won't quite line up as well, and you might miss spots, as I did in this one of the Alamo.

    Or this one in the torpedo room of the USS Blueback in Portland, Ore.

    But if things work out, you get a reasonably good shot, like this one:
