Camera manufacturers should release a sensor with R G B B B B B B B configuration so that Tony can finally be happy about the noise level in the skies!

ISO is applied gain. Ambient lit exposure is* aperture vs shutter speed. The ISO 50 shots were cleaner because double the light was captured.. i.e. via halving the shutter speed. This same can be achieved without ISO 50 - if using the base ISO 100 just simply overexpose a stop via shutter or aperture and pull back in post.... Its called "shooting to the right" (of the histogram)

LOVE THE QUICK TIPS
right to the point and
not going on about
how your day was

I do photography at the beach often in the Cayman Islands and use ISO 50 pretty often, not for the improved image quality but for the ability to lengthen my shutter speed when I just can't get the amount of movement in crashing or receding waves that I need. I feel this is a better reason to use ISO 50.

I seriously feel like I learn more with every video I watch from you guys.:) thanks for being on YouTube. Without a doubt one of my favorite channels

[danieleubank]

apologies for the interruption but was a pleasure meeting you all here in Riverside, keep doing what you do, love the channel and always valuable information you all provide, especially enjoy your podcasts! thanks and have a great time and safe trip back

Great video. Makes me think about different ways of taking and processing pictures. I've seen charts where extended low iso reduces dynamic range, but you've shown the difference between technical results vs real world. Thanks again!

[jongrall]

I've actually found myself using the low extended ISO when I needed to slow my shutter speed down to blur running water a little in daylight when I don't have my ND filters with me. This produces a better result than stopping down your aperture beyond the optimal range for your lens and introducing diffraction. Good to know that ISO 50 can actually result in lower noise when you don't need the full dynamic range and highlight recovery.

[DmitryBrodsky]

thats why it is great to have native ISO60 on D810

[patspencer]

Thanks for the tips....on a completely unrelated note - I love the videos as it virtually takes me back to my grandparents beach on Pequot Ave overlooking the New London Ledge every time I visit my parents we go for a walk on that boardwalk Niantic Bay.

I know you did an image averaging video already but you should do a tutorial on night photography in particular the Milky Way and incorporate image stacking and how you would properly align the stars. It'd be good content and a fun shoot

I usually use ISO 50 when shooting outdoors in bright sunlight, and want to open up the aperture of the lens to the maximum (f/1.2 or 1.4).

[DJewell]

Thanks, you just answered my burning question, "why not use ISO L(50)?". I just recently planned on changing and testing my camera using ISO L (50) but haven been able to test it out yet. Still recovering from shoulder surgery. I bought your book a few years back and it helped me a great deal.

[WaniMedia]

I ALWAYS use extended lowas much as possible with fast glass! always works for me on post and raw files 12 or 14 bit.

[rocheuro]

or shoot iso 100 and overexpose (but try not to burn highlights) than lower exposure -1 in post.. and you have virtually ISO50 on your ISO100 camera.. ;) - you're welcome!

[ales_krejci]

basically if you shoot in any semiautomatic mode and compensate +1EV you get the same result (and then making it back -1EV in post), you could do +2EV for even stronger effect etc., but I dont thing this means higher dynamic range, just less noise in shadows and it comes with a cost

[KaoukabiJaouad]

ISO 50 even if it not native is basically like ELTTR (Exposing a little to the Right) exactly by one stop, it's ETTR for people who don't know what ETTR and sensor saturation means(works outside when you have plenty of light), but the big question is, how good a native low ISO less than 100 compared to a non native one, you should have compared 2 pictures on a D810 the native 64 ISO compared to an ISO of 100 ETTR by one stop and underexposed by one stop in post

[Sondercreative]

Thank you for making this video Tony, I really appreciate it. I can't tell you how useful this information is to me.

[armandot]

I have been doing this for ages and people always said it made no sense. Glad to hear I am not the only one now seeing this

Temporarily abandoned the Lumix G9 DSLR....in favour of hammering out photographs using an Asahi Pentax S3 35mm SLR [manufacture of which was discontinued in 1962]...via 200 and 400iso b/w and colour positive 35mm film. Could I possibly learn more about iso and other variables by taking up the heft of an old SLR camera which does not use batteries? Was my DSLR encouraging me to spray and pray? Time will tell. Have not developed the photographs yet....they may all be ghastly. Great video. Thank you again x
