M ore options for low light and/or high ISO I tried some chroma noise reduction in LR prior to the stacking, but the result was softer and the noise was about the same.Īgain a 1:1 crop comparing the result on the left and one of the original images on the right No processing of the images before the stacking, only the standard LR settings. The high ISO have never been of any interest for me, but as a final and extreme test here is ISO 64.000 hand held from 12 shots made with the A7RII and the Zeiss Otus f/7.1 Here are the crops of the native ISO settings from 100 to 800 ISO The results did not show any significant differences and are useless to show here in web size.Īnd I wanted to know, how the original images with the native ISO settings compare to the above results I did the same test with ISO 100 and wanted to know, if even at base ISO this improves the noise in the shadows. * tripod (no alignment of the pictures necessary),Īgain a 1:1 crops comparing the result on the left and one of the original images on the right * with the less modern APS-C sensor of the A6000 The following images are made under controlled circumstances in my living room with light from the window The flag in the foreground looks almost like a long time exposure, hand held!Ī 1:1 crop comparing the result on the left and one of the original images on the rightġ:1 crop, original left stacked right, both with same LR developemant Next image is the Christmas Market in Hamburg Stacking of hight ISO hand hald images, stack of 8 to 12 shots stacking of hight ISO hand hald images, stack of 8 to 12 shotsĪ 1:1 crop comparing the results on the left with one of the original images on the right It was late at about 11 PM and very dark and the sky was illuminated from the city but looked much darker than on the pictures after the processing. Next images from the Hafencity are all made at ISO 10.000 and stacked from 12 shots The first images where made on a trip to the Hafencity and Christmas Market in Hamburg.Ĭlick on the images for higher resolution and a better impression of the incredible improvement of the technique! It takes some time for processing many 42 MP images on my system :-) * crop image to eliminate some empty space at the edges from camera moving during the shootingĪfter the first tests I made an action in PS and now I just have to start the action and can do something else. * layers: Smart Objects -> Stack mode -> Mean * layers: smart objects -> convert to smart objects * I use LR and export the images to PS as layers. * load the images into Photoshop as layers * make sure, that you synchronize all images * I tried to reduce the croma noise but found, that the results get softer * I did not do any editing in LR, only the standard settings (for example sharpening) * I compared the normal shutter with the silent shutter and found a small advantage of the normal shutter Long time ago I used this technique with the Nikon D3 and the base ISO 200 and got impressive improvements in the shadows. ![]() * when the scene is not static enough (obvious: not usable for street shooting)īut even with a tripod you may consider to use this technique at low ISO and reduce the noise in the shadows. ![]() * when it is not enough light for hand held shooting with low ISO even with open aperture and OSS lenses and/or IBIS camera * obvious: when you don’t have your tripod or can not use it or it is forbidden Layers: Smart Objects – Stack mode – Mean If you don’t have or can use a tripod shoot some images (better more than 4) with high ISO hand held at ISO 6.400, stacked from 12 images noise suppression with stacked images ![]() Made with the Sony A7RII and the Sony 16-35mm Vario-Tessar T FE F4 ZA OSS hand held 1/20 sec. The problem that day was, that it was very windy and the tree and the flags where moving a lot. After learning the processing in PS I found, that I should try even higher ISO the next day. ![]() I got so exited, that I went out and started shooting the Christmas tree in front of our beautiful townhall with up to ISO 6.400. You will get a feeling for the amount of pictures depending of the exposure time it may take a while. You set the camera on Hi continuous shooting and shoot a series of pictures. This can be very effective with high ISO and especially with small sensors. The main idea is, that by stacking multiple shots of exactly the same scene or object the different noise patterns of the images get combined and disappear. In astro photography this method seems to be very common, but using it for any hand held shooting is something different. The link to the tutorial follows at the end. I found it at, my favorite photo site with incredible picture series. Shooting very high ISO and get clean images with (almost) no noiseĪ few days ago I saw a great tutorial about achieving high ISO images with low or almost no noise.
