Join Seán Duggan for an in-depth discussion in this video Noise reduction on raw files, part of Enhancing Night and Low-Light Photos with Photoshop.
…Even though noise is something that you have to deal with is you're shooting at…a high ISO setting,…the raw processing engine in Adobe Camera Raw can help to reduce noise.…It won't be able to remove the noise completely but it can make it…much less noticeable and reduce it until it reaches a more acceptable level.…And not all images that you shoot with a high ISO are necessarily taken at night or…even in particularly low light conditions.…Sometimes you have to use a high ISO because you need to…use a fast shutter speed, to stop fast motion.…
So just with this shot of an Irish dance competition.…If we look at the exposure information up here,…you can see that I'm at 1/250th of the second and…my ISO is all the way up to 25,600 which is just an astonishingly high ISO.…It's truly amazing what digital cameras are capable of these days.…Now, one other thing to point here just in terms of…a general photographic tip is that my aperture is F5.6 so.…If I had been able to use a wider maximum aperture,…I could've gotten by either with a lower ISO or with a faster shutter speed…
In this course, photographer and educator Seán Duggan explores a range of post-processing techniques aimed at expanding your creative options for night and low-light photography—and even "shooting" stars. He'll begin in Camera Raw for general enhancements (white balance, tonal and contrast adjustments, and noise reduction) and then turn to Photoshop to capitalize on its Merge to HDR feature, which can create spectacular high-dynamic-range images. Last, he includes techniques specifically for star photography: stacking layers to create star trails, removing and replacing blurry stars, and using luminosity masks on photos of the Milky Way.
