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.

How to get extreme close-ups with the camera you have

     I've always said that photography can show you things that you can't see, as well as record the things that you can see.

    One of those ways is macrophotography, where you can go in for extreme close-ups of various objects. This allows you see details that may not be readily apparent to the naked eye, as well as create a new perspective on an otherwise mundane object.

    There are dedicated lenses for macrophotograpy, as well as filter-like diopters you can use to magnify the image in your lens. There are also extension tubes and even bellows that can put the lens farther out to create a close-up image.

    But if you don't want to invest in that gear, especially if you're trying out macrophotography for the first time, there are a couple easy solutions.

    If you're using a cellphone camera, you can use a simple magnifying glass to get a closer look. Just put the glass in front of your lens and you might have to move your camera back and forth to bring it into focus.

    That's how I got this photo of a coin commemorating the 75th anniversary of the B-17 "Memphis Belle" completing 25 missions over Europe in World War II.

    If you are lucky enough to have a camera with a removable lens, there's a way to get a great macro shot. It's a tip I first learned in high school back when we were still shooting film.

    Take off your lens and hold it up backwards against the camera's lens mount. You'll have to hold it tight to prevent a light leak and then move back and forth to get the image in focus. If you're using a lens where the camera sets the aperture instead, you'll have to hold your finger on the lever that adjusts the aperture to get it to stay wide open.

    I took this shot using a 50mm f-2 Rikenor lens that I reversed.   

    For perspective, here's a shot of the same coin, taken with the 50mm properly mounted on my camera.
