![]() ![]() Cleaner images with less noise come as a result of exposures where more overall light is collected. The reason for doing this is to take advantage of the way your camera works. If the bright parts you care about are blown out (too bright), they will clip meaning all detail will be lost in them forever. In other words, exposing based on the brightest parts of the scene. So, what is it anyway?Įxposing to the right simply means to expose your photo while yielding mainly to the right side of the histogram. Another phrase is “protect the highlights” which sounds more like under-exposing. To some, it simply sounds like over-exposing. This is a phrase that can cause confusion among photographers. It is the aim of this article to help photographers to utilize the full dynamic range of their cameras and when possible, get the shot with a single shutter actuation and then process that photo in a way that achieves the artist's vision. For example, if there is a moving subject, or the camera moves slightly between exposures artifacts will be created and problems will arise. There are other pitfalls of a multiple exposure capture. Likely due to the fact that it is easy to “over process” these images and create a final product that goes beyond reality and into the realm of surrealism. In many circles, this type of photographic capture technique and processing has plummeted in popularity. For reference, the human eye is capable of somewhere in the neighborhood of 20 stops of dynamic range. The reason this type of photography exploded in popularity is because, to some degree, it emulates human vision. HDR has gotten a bad rap in recent years, not because there is anything inherently wrong with the technique (it's just a tool) but because of a sort of ebb and flow of taste in art. The photos are then processed though some sort of HDR software system which uses data from all three photos to create a starting image with very low contrast and detail throughout the tonal range.įrom this point, the artist takes over and starts adding contrast back into the image selectively and making other adjustments as necessary (or not). This method of capture involves taking 3 or 5 separate images in succession (bracket) with one “standard” exposure one underexposed and one over exposed image. Imagine a scene with very dark areas where detail is important and a bright background with color and detail that needs to be captured to meet the artist’s vision. It has become common for photographers to utilize multiple photos to capture a wider dynamic range in a scene. Visit Photons to Photos to interact with this chart. This chart shows a photographic dynamic range comparison of several popular camera systems. This should be enough to capture your vision. If you don’t have $50K+ to drop on a camera system, don’t fret, most popular DSLR and Mirror-less Full Frame cameras come in around 10.5-11.5 stops. This means that the difference between the darkest usable areas of a photo and the brightest usable areas is equivalent to 13 stops of light (39 clicks on the adjustment wheel of most cameras). According to the PDR (Photographic Dynamic Range) Charts at Photons to Photos the Phase One IQ3 100MP sports the highest PDR at just over 13 stops. Some camera systems are better than others at capturing detail across a wide range of tones. This refers to the camera’s ability to capture and retain data from the very light to very dark.Įquipment matters. Images are obviously captured by a camera system, so references are made to a camera’s dynamic range. Simply put, it’s an image’s ability to retain detail in the dark as well as the light areas in the image. Sometimes, it even seems that there is general confusion on what HDR is. It’s also more than those gaudy, over-processed images you sometimes see in your Instagram feed. It turns out that HDR is more than just that mode on your iPhone that seems to work magic. Modern digital camera systems have come a long way in allowing the photographer to capture this detail. In a given scene, there may be a desire to capture details in both the very bright and very dark areas of that scene. Easy HDR photography without bracketing is about using a single image, rather than a set of images to capture more detail in your scene.
