Yomo Posted October 1, 2016 Share Posted October 1, 2016 On my A7s I noticed that when shooting in SLOG2 if I go up to ISO 8000 the image will have a different noise pattern than if I go up to ISO 10,000 and then down to ISO 8000, same ISO but totally different noise I know that people have reported a similar issue with the A7sii with SLOG3 but what I read was it was believed to only be a bug with that picture profile It's this kind of "Trick" ISO that does something weird to the noise Going up give the ISO a kind of "Dirty" grain but going down to the very same ISO will give the ISO a "Clean" grain I compared Native 3200 to this ISO 8000 when it had a "Clean" noise and also the "Dirty" noisehttp://imgur.com/RzOCZkohttp://imgur.com/AWU0IEDhttp://imgur.com/G6QoXWl The thing is I see this not just on SLOG2..I see it on all picture profiles..on multiple different camera models... On the A7s this happens on the following Picture Profiles on the following ISOs:http://imgur.com/SLmoyEF Here is a video of me going over the issue and explaining more in-depth:https://youtu.be/Omp5SMrifwI Dan Wake 1 Quote Link to comment Share on other sites More sharing options...
