The trick is to make a selection of an exposure, based on that exposure’s luminosity.
CAPTURING REALITY RAW FILES SOFTWARE
There’s the dedicated software I mentioned earlier, but there are photographers, including myself that do it all by hand. In practice, just about every photographer has his or her own approach to expanding the dynamic range of a given camera. It’s where the name of high dynamic range imagery finds its origin: If one photo doesn’t contain all the information of either shadows or highlights, the dynamic range of the device it’s captured with, isn’t enough for the scene you try to photograph. This theoretically makes it possible to properly expose the highlights as well as the shadows in the harshest contrasts.

CAPTURING REALITY RAW FILES SERIES
Most often, the idea is that you capture a series of exposures where every setting on the camera is the same, save for the shutter speed. Whether you run Photomatix, HDR Expose, or use Lightroom to blend your images together, I’m sure you’ve heard of expanding the dynamic range of your images. Everything Exposed As Seen with the Human Eye with HDRĪ more familiar exposure blending technique is of course high dynamic range imagery. But because diffraction is a physical property attributed to the way light hits the sensor, even the sharpest lenses out there will not be as sharp at their minimum apertures.Ģ. Why is this useful?Īs focus stacking will be very useful at your lens’ sweet spot, even the cheapest lens will appear to shoot razor sharp images, rivaling the single shots of the pricey contenders at smaller apertures. At f/22 though, diffraction plays a detrimental role in the sharpness of your image. Even with the slightest breeze, delicate foreground elements like flowers, grass and ferns will for sure sway and actually make the foreground look less sharp than say f/7.1.Įver heard of the sweet spot of the lens? That’s the aperture at which your lens produces the least amount of aberrations while keeping diffraction to a minimum usually one to two stops down from wide open. At the same ISO, this will lengthen the exposure time (shutter speed). For starters, you will let less light in. Closing up the aperture has some nasty side effects. Dial in f/22 on your wide angle, set it to its hyperfocal distance and everything should be tack sharp. These are the raw files that have been used, with the green outlines showing you the parts that made it into the final image below. Note that you will need more exposures at shorter distance intervals when you use a larger aperture like f/5.6 and less at smaller apertures like f/11. Repeat this process until you’ve reached infinity. Hit the cable release and adjust to focus a little further into the scene. Start by adjusting focus to the closest object in the scene and wait for the wind to die down for a bit. The one difference is the focus distance.

CAPTURING REALITY RAW FILES ISO
For the best results every setting on the camera should also be exactly the same: White balance (fixable in post when shooting raw), shutter speed, ISO and aperture. Making sure you’re using a solid tripod and shoot with a cable release takes care of the physical movement of the camera. With focus stacking, you’ll need to fix everything in place throughout multiple exposures. But what if you wanted to also capture a sharp background? That’s where we shift our attention to landscape photography. Kicking things off is a technique that originated in macro photography to capture a sharp subject and still have that creamy background. I’ll show you the techniques I often use to translate my vision to the image. So how do you make that mountain appear as large to the viewer as it does to you? How do you get rid of noise in your nightscape images? And how can you get everything in perfect focus, front to back? This might as well be titled “5 Things you can’t do in one shot,” since each technique in this essay relies heavily on layering multiple exposures of a given landscape scene.
