    I have finally seen where to adjust my shutter speed, thank you

  2. @mikays7059 on October 29, 2024 at 9:11 pm

    yeah this is definitely easily the best well explained video of these 3 features and short too. awesome.

  3. @pastuh on October 29, 2024 at 9:12 pm

    Super simple 🙂

  4. @BlayVision on October 29, 2024 at 9:13 pm

    Really well explained and easy to understand thank you.

  5. @designer_muhammadali on October 29, 2024 at 9:13 pm

    If ISO is set to auto, how does it affect exposure? In other words, is there any relationship between ISO and exposure?

  6. @bobbyboo2860 on October 29, 2024 at 9:14 pm

    this is so good and straight to the pt!!

  7. @seanpuello on October 29, 2024 at 9:16 pm

    ohhhhhhh… so pick one first based off the picture your trying to do and then adjust the rest

  8. @44REXZ on October 29, 2024 at 9:18 pm

    Awesome job!

  9. @davthemarketer8975 on October 29, 2024 at 9:19 pm

    Wow, this made it so simple and clear for me. Thank you.

    This is very helpful!

    Aperture is the size of the hole that lets light come into the camera

    By changing the aperture we are able to specify how much our subject stays in focus.

    Shooting in a larger aperture, creates a very narrow area of focus.

    Taking the aperture down, gives us greater depth of field with more of the subject and background in focus.

    could not be more precise on the way you explain, perfect video !

  13. @ArtByYadu on October 29, 2024 at 9:23 pm

    Well said

  14. @rachelw345 on October 29, 2024 at 9:25 pm

    Thanks for the great video! I’ve just bought my first DSLR and trying to use manual. I have a rough idea now of what settings work best for different styles of photo, but how do you know which numbers to use for each element? Is it a case of playing about with the 3 until the photo turns out well? Or does it become second nature with experience? Thanks

  15. @ToniTheBlackCat on October 29, 2024 at 9:26 pm

    Thank you. I will start soon

  16. @Shenanigans000 on October 29, 2024 at 9:26 pm

    Amazing! Thanks for

  17. @Mo.W4SEL on October 29, 2024 at 9:27 pm

    WoW the best video in 2024

  18. @Treborray on October 29, 2024 at 9:28 pm

    Thank you for this! I just bought a camera

  19. @hannahruthwalker6867 on October 29, 2024 at 9:28 pm

    This was such a helpful video, thank you. So clearly explained!!!

  20. @walterdeminicis737 on October 29, 2024 at 9:29 pm

    If increasing ISO also increases noise in the dark, why would you really increase it for shooting in the dark? Shouldn’t it be as low as possible to preserve the dark?

  21. @jackpepkowski4083 on October 29, 2024 at 9:30 pm

    1:30 “Shooting at a larger aperture…creates a very narrow area of focus”

    1:52 “The smaller the aperture, the more overall focus in the image”

    HUH????

  22. @OceanInfiniti on October 29, 2024 at 9:34 pm

    Russell Crowe is that you?

  23. @Hugex97 on October 29, 2024 at 9:35 pm

    6 years after, the best video ive come across. i can now get away from premades and trust my own manuals. Thanks!

  24. @zyaygo on October 29, 2024 at 9:37 pm

    Does the same apply for videos?

  25. @AyetchMusic on October 29, 2024 at 9:38 pm

    Great video!

  26. @kedralive on October 29, 2024 at 9:41 pm

    Omg that amount of noise at 20K is anything compared to my phone on 1600 xD (S23 Ultra)

  27. @deeanna8448 on October 29, 2024 at 9:41 pm

    Thank you! Aside from cell phones, and the cheap little cameras that came wrapped in hard plastic containers from Walmart, I have never owned a camera. I just purchased a used Canon because I’m going on trips to Africa and Antarctica and am waiting for it to arrive. I did not understand any of these terms, and your video was really helpful. I can’t wait to start experimenting!

  28. @chw5044 on October 29, 2024 at 9:43 pm

    Perfect, easy, and simple…

  29. @nonaubiz8939 on October 29, 2024 at 9:43 pm

    This extremely helpful, now I understand how I can improve a recent photo next time I shoot it. Thanks.

  30. @firefeethok_tui2355 on October 29, 2024 at 9:43 pm

    Excellent…thank you!

    To anyone coming fresh to this video, like most of those made at the time when content producers were blindly following the ‘exposure triangle’ the stuff it presents about ISO is completely wrong. ISO is not ‘light sensitivity’ (ISO does allow it to be called ‘sensitivity’ but only under its own particular definition of that word) and neither does it ‘introduce noise into the image’, as said at 2:30. The noise you see in photos taken at high ISOs is due to low exposure, not noise being introduced into an image. Most image noise is a thing called ‘photon shot noise’; which depends on the number of photons (light particles) captured in an image. Low exposure means few photons and thus more noise. High ISO causes low exposure because it sets your meter to centre at a low exposure – that is makes ‘correct exposure’ small. This particular error springs from thinking that ISO is part of the exposure ‘trinity’. It isn’t – the ‘trinity’ is aperture (strictly f-number), shutter speed and scene luminance – the amount of light coming from your scene.

    I’m new to film photography and this was the BEST way to explain these three topics to someone new like me. Thank you for the simplicity and straight to the point explanations!!

  33. @JC_500 on October 29, 2024 at 9:47 pm

    Who knew B&H could make such a good and straightforward video?

  34. @SomethingGamecatAdjacent on October 29, 2024 at 9:49 pm

    I can’t believe how perfect this video is

    My notes from the video:

    ■Shutter Speed■
    – The moment between the opening and closing of the camera shutter/The time it takes for the camera to take the picture.

    • For objects moving fast, you need a high shutter speed.
    • For still objects or to capture motion blur in the picture, you need a lower shutter speed.

    ■ISO■
    – Controls the light sensitivity of the image.

    •In well lit environments, you can use a smaller ISO.

    •Darker environments will require a larger ISO to allow more light, but this also introduces noise to the photo.

    ■Aperture■
    – The size of the hole that lets light into the camera.

    – The smaller the aperture is set to, the larger the hole will be.
    – Aperture also allows you to specify how much of an object you want in focus.

    ▪Using a smaller aperature (larger hole) creates a NARROWER area of focus. Allows for a much clearer focus on an item while blurring the background.

    Crazy how a 3 minute video manages to explain something so many 20 minute videos can’t even explain. GOod job whoever scripted this guide.

  36. @AgensOwusu on October 29, 2024 at 9:51 pm

    Thank you sir. You are a very great teacher.

  37. @EYNGohu on October 29, 2024 at 9:53 pm

    Those are the best videos ever! Simple, fast and so easy to understand

  38. @kbboy101 on October 29, 2024 at 9:56 pm

    Thanks for the easy and clear explanation. My university professor who specializes in imaging and vision did a poor job and the text book just takes you to another dimension where you have no idea what they are talking about.

  39. @marshan34 on October 29, 2024 at 9:58 pm

    OMG, I can’t believe I caught on to what was being said so easily. I have watched several videos and this one hit home. Thank you for the info with the visuals.

  40. @booza3730 on October 29, 2024 at 9:59 pm

    What the name of song background

  41. @dartmoor.adventurer on October 29, 2024 at 10:00 pm

  42. @yshvergara2544 on October 29, 2024 at 10:02 pm

    I’m a beginner and I appreciate your simple and easy to understand explanation! I hope all videos are just as simple and straight to the point as this! I really learned a lot!

  43. @the21stcenturymystic on October 29, 2024 at 10:03 pm

    my father was a photographer and he passed away. im now studying A Level photography at college and i want to make his soul proud. thank you for this video, very well articulated but understandable and precise for beginners. gem of a video 🩵

    Amazing, thank you.

  48. @lj9497 on October 29, 2024 at 10:04 pm

    Does this work the same on a SLR?

  49. @idk4399 on October 29, 2024 at 10:04 pm

    thank you so much for this! helped me tons 🙂

  50. @todei79 on October 29, 2024 at 10:08 pm

    The absolute best beginners intro I’ve seen to date. Thank you so much.
