5 minute Fridays should be mandatory for all discerning astrophotographers. Thanks, Nico!

You could literally do a years worth of 5 minute Fridays on this topic. Good primer Nico.

as someone wanting to get into astrophotography I can't tell you how helpful this was. I've watched tons of videos showing adjusting the image using the histogram, but never understood what it was. Thanks for the simple, easy to understand explaination.

Long ago, after a couple years playing with my first digital slr and still shooting everything on Auto or “P”, someone said to me, “learn to use the histogram and it will change your life.”
And it did.
But took me a few weeks to realize that it really was as simple as what you just explained in 5 minutes.
So, yeah. Wish I’d seen this back then 🤗.
Meanwhile, I know *nothing* of astrophotography, but finally moved to a small island where the night sky 🌌 is often clear and dark and amazing. So now I’m interested, and planning to binge-watch your channel videos 🙏🙏🙏

Week 23 of appreciating Five Minute Fridays

[mahir_m]

That was explained really well... Thx Nico

[fazergazer]

Super clear. That was a 32Bit subject expressed in 8! ;)
Just a ‘bit’ of humor there!

Taking a mechatronics class in school and just finished my exam on Analog to Digital signal conversion. This video would have really helped me pass that exam haha

[davidpomfret]

I am grateful to you for helping me on my astrophotography journey.

[Spaced_Out_Bill]

Thank you! I have always been a BIT confused about this topic.

[simonpepper]

Not just good at taking photos Nico genius explaining how it works too!

[quentinblanc]

Despite knowing all of it already, this was well worth watching and felt like 30 secs. Thank you.

[noddyonice]

Very well explained Nico. Even I understood it! 👍🏻 Noddy

[victormultanen]

such an unusual representation of bitdepth for photography! Love from Israel

[avt_astro]

Fantastic Video Nico!! Love These Informative Camera Specs, You should do a Lot more!! In your Next One, You could Include, 'what Is Full Well Depth' pixel size for Astrophotography. This is Was Very Informative!! Loved it!

[briankotak]

Brilliant explanation of bit depth and the histogram with the tea cups. Very effective and easy to understand. I had to laugh at the green computer screen. I am of the vintage to remember those computers (which were soooo powerful). Dr B from Manitoba

[neodanks]

You explained this clearly. Thank you!

[ABFerrelli]

This was the best explanation of histograms and bit depth I've seen! Thank you!

[spidersj]

And one needs to use 16-bit TIFs on digital cameras because the sensors are 12-bit or 14-bit you need a 16-bit "bucket" to dump that sensor data to. If you're stacking hundreds of 16-bit images having the flexibility of stretching that image stack for bringing out all the subtle nuances of dim objects you will indeed need 32-bit to 64-bit per channel resulting image files so you don't clip anything prematurely.

Great Nico! This is the kind of subject that many avoid- it is hard to explain succinctly in an interesting way.
