what iso should i use for night picture i have a canon 1300D. what Aperture and shutter speed should i been useing

[@sinjon]

Tony when you say divide the focal length and aperture by your cameras crop factor, which focal length and aperture are you referring to? What if the aperture is for example, 1.4 or 1.7? Confused

[@Tekka579]

Just want to thank you for an amazing channel. I went from knowing nothing and talking terrible photos to purchasing my 1st camera and vintage lens

[@Thefastlane425]

For people questioning whether to buy this book or not.. Figure this... This is what they are giving out for free, just imagine what's included I their books. It's excellent

[@sethshaffer8592]

+Thefastlane425 And their electronic version is only about 9 dollars!

[@PERGEAR]

+Seth Shaffer more people will buy it sooner or later.

[@LoboOutdoor]

Dam good point

[@blurayauthority]

The best part (for me) is inclusion in the Facebook group. I have learned more there than in the book. Not to knock the book, it's great, but that interaction with others is what has really helped me.

[@SargsyanTigran]

That's what I was thinking too. ))

[@FF-dz6cx]

Finally, finally, aperture makes sense to me once you explained it mathematically. Thank you for approaching it in various ways.

[@michaelbevington7468]

I'm sharing this with my daughter because as many times as I've explained it the more confused she gets. The visualization method you used is fantastic. You three really nailed it with this short tutorial.

[@WilkineBrutus]

You two are absolutely brilliant. The presentation, the concise information, personality, technical knowledge - great video for beginners, intermediate and pros.

[@itschriswinter]

This was absolutely fantastic, what a brilliant video for beginners tony and Chelsea.

[@davidchindumbo7637]

+Chris Winter You ave awesome videos, too.

[@TonyAndChelsea]

+Chris Winter Thanks, Chris!

[@jesuskinz1232]

Hi. How much marijuana do Tony and Chelsea smoke? Do they drink whiskey?

[@lexielexie3653]

This is awesome! my 2 favorite youtubers/teacher are complimenting each other. Thanks to you both

[@crocellian2972]

I have been shooting since everyone packed two bodies, one loaded with Tri-X. That split screen thing you did in the first minute was the best teaching moment I have ever seen. I will steal it immediately.

[@neolithian]

I understand what Aperture, f-Stop and DOF are and how they work (at least theoretically :)) . But I watched the full video just for I loved the way you guys explained all these things. Tony & Chelsea, you guys are so good at explaining photographic science! Salute!

[@Trotskyification]

This video is very timely, my mother who is 76 and just bought a Nikon D3200 is coming over today to learn about aperature. This video is excellent I will go through it with her - you guys are great teachers. Everything I know about photography I have learnt from you books and videos.

[@MisterTDiSalvo187]

Some of the best videos I've found explaining camera functionality. Direct and to the point without life stories or opinion. Highly detailed and informative. Highly recommended. Much appreciated

[@michaeljones6341]

i learn more and more with each video, since watching this channel taking a photo isnt just taking a photo its so much more. my skills have got better and my knowledge increased and my respect towards professional photographers gets bigger!

[@martinpospichal8937]

Tony and Chelsea, you are hell a good teachers. This video is brilliant, informative, sticking up to the point. For me your best video up to date!

[@TonyAndChelsea]

+Martin Pospíchal Thanks, and glad we could help!

[@mustream1234567890]

I have learned more from you guys and these videos than i have from anyone/anywhere else... Thank you for what you do Tony & Chelsea

[@k2s3p]

One of the best videos I have seen on your channel T&C. Your explanation is very lucid and to the point, especially when you explained the science.

[@jackedupjunkers1922]

I know when i was beginning photography I avoided these videos because i didn't see the need to and didn't think they would help. Now its evident to me for the that is not the case! you may have the knowledge of what it is but as one of my favorite KZbinrs says "knowledge is not understanding"! it is so important you you understand what this does because once you understand then you can apply it usefully to your photography! Great video!

[@MyplayLists4Y2Y]

Best photo/video review channel on the web!! Thumbs up!!

[@markfrank0924]

I like how people and this is true here as well as elsewhere will look at an excellent tutorial like this one and somehow feel the need to add to it, correct or make other unrelated comments. Why not just appreciate what teachers are teaching and add that to your knowledge. Why this need to added to or take away from what the teacher is attempting to teach? Excellent site with excellent professional instruction.

[@Nawabid]

BEST TUTORIAL on Aperture and f/stop by far! Thank you. I have learned so much from your tutorials that I can go back and look at the pictures as I watched your videos and notice it getting better and better!!

[@staceyfougere1424]

As a beginner photographer, I can honestly say this is the best video I have found to teach me how to take desirable photos. I have researched f-stops, depth-of-feel, over-and-under exposure, etc., but by watching this video, I now understand better how they relate to each other, and how adjusting your f-stop can fix a number of the issues you might run into when taking photos. Thank you so very much! I will definitely subscribe to your channel, and I hope to purchase your book in the near future. Well done!

[@TonyAndChelsea]

Glad to help!

[@wendylilja5154]

I've tried learning more in-depth about my Nikon but the typical youtube videos just aren't that greet. Since finding Northrup educational videos and their book, it all suddenly makes sooo much more sense! Thanks!!!

[@brianmc2354]

Wow so much more information than I was expecting. Added to my queue to watch again when I get home.

[@TripleMachine]

Been subscribed for little over a year and this is by far the best video produced. Thank you for this tony and chelsea!

[@AlmightyyCres]

you guys are guiding me further into my hobby. just picked up my first real camera an A6300. been shooting on phone for years.

[@johnbautista1150]

The best video about aperture I've seen yet. Mahalo and Aloha.

[@kellanbacon9956]

This is the best explanation and tutorial of how to use F stop settings!!!

[@Midpack4]

I've seen many explanations on aperture over the years, this is the best explanation I've ever seen! The Northrups's videos and books are among the best resources out there.

[@anildangol]

This is how mentoring should be done! Teaching technicalities in basic way is the best way of teaching. I have seen lot of other videos where they teach various technical things in their own way which is way over the head for someone who is just learning photography. You guys are doing amazing job at this considering all kinds of students in different level.

[@romibhattacharya116]

I am so thankful to you for this informative video..I take photography club in school for kids and it's so hard to drive concept into their head .I have struggle a lot with f stops...now I can simply show this video and I am 100% sure that they will get it..loud and clear. Thanks a lot again. DB

[@liebabettencourt3799]

I really really love Chelsea and Tony. their videos are easy to understand and follow, and they make photography way to learn especially as I am a complete newbie to digital photography. thanks guys 👌👍

[@terrancechavis2521]

I love, love, love your "how to" and tips photography videos. You make the basics and complicated topics very easy to understand. Even for experienced photographic enthusiasts like me.

[@raylee8864]

after a year of owning my Nikon d3200 iwas in a state trying to get to grips aperture,F/stop& depth of field and got no where but thanks to your video on you tube i have got my happy head on again i am learning thanks to you two i have subscribed and hope to learn more,think i have picked the rite hobby for my retirement,Tank you so much. Ray

[@TonyAndChelsea]

+Ray Lee Glad I could help!

[@squib9]

I'm new to photography basically a novice, started being serious about it maybe a year ago(ish). I found your channel when I was searching for good dslr camera reviews and one of your videos popped up. I picked up a used 80D shortly after that which I figured was a steal based on its reviews. However, I subbed because you guys are very good at explaining AND demonstrating your knowledge in a range of different areas it's very inspiring

[@PHX1138]

I am a public affairs officer and normally I won't use a camera. However, I feel it is important for me to understand these things so I know what my team is doing and what right looks like. I recently picked up a Canon 80D since we use Canon. I have been all over the internet doing research and I must say, this video and your others are exactly what I am looking for. Your descriptions and guidance are perfect for the beginner. Thank you.

[@international_connections]

Tony & Chelsea, I want to thank y'all for creating these videos, I've been watching them all and I must say I've learned a lot. Just wanted to let you know your work is very much appropriated! That's all 📸

[@JasonPatz]

There are lots of videos that talk about these points, but few seem to do a great job showing them. You guys did a very good job with your examples in this video. Great information and nicely presented.

[@TonyAndChelsea]

+Jason Patz Thanks!

[@eddiedownes9084]

Wow, I have been frightened of the technicalities of the camera for years, point and shoot in automatic was the best I could do. Doing a tutorial KZbin video on my new EAoS250D with Michael the Mavin and he suggested before going further with his tutorial to look at yours on f stops. It’s brilliant, for the first time I am beginning to understand the tech bits, as well as learning about the camera from Michael. Yes, I will probably have to watch both again for it to really sink in, and that’s just the basics not the real techy bits, but even to begin to understand how to get two subjects into focus has propelled my learning light years ahead of what it was. Thank you guys from a currently very much wetter than usual North West England.

[@JHImagescouk]

A quick comment, this has to be one of the best put together videos about these subjects I have ever watched. Keep up the good work.

[@itechflagstaff]

Thank you so much for all you do. I have learned more from your books and videos these last two years than the previous 15 I spent trying to learn photography.

[@guilhermeribeiro5630]

This was the first video I watched from the channel. Definitely I'm subscribed now. Probably the most well explained video I have seen. I just bought a DLSR and as a beginner I am looking for information. Not only I could understand the different aspects but also increased my excitement to start taking pictures. Thank you.

[@VipulDK]

This is one of the best videos on understanding the basics out there! Very well done creating and sharing this.

[@TonyAndChelsea]

+Vipul Kapadia Thanks!

[@gigih157]

Just replaced my old Canon 20D with an 80D. Your videos and tutorials have been unbelievably helpful in my quest to become a better photographer. Thank you!

[@mountainhobo]

Very well done, Tony. Finally there is a clear video on the subject I can recommend to anyone starting in photography.

[@annnelson437]

Just starting to get serious with photography and your videos are beyond helpful!!! Great information! Even love how you gave the equation that gives the F stop number- it makes perfect sense to me now!

[@robertclark9567]

Much appreciation for the balance of the novice info to start learning and the need to grow in to use the many options on modern cameras. Great job!

[@humanll8965]

I'm a beginner photographer and I really love your guys videos, they are a life saver on many levels. thank you this means a lot to me.

[@ltwing2]

This is by far the best I've seen on this subject. I love the slow explanations along with effects of making the changes and the technical reasons thrown in too. As far as your book, I bought before I even discovered your KZbin videos and am glad I now have two of your resources. Thanks.

[@robertneville4469]

You guys are killer professionals! Not just with cameras, but your videos, the knowledge transfer - on point 👌

[@adaseth]

Finally, their live videos suck but the prearranged ones- one of the best of the best. Really love that they go that much into detail, explain everything and do it with class :) They just don't know how to play by ear :P

[@smaakjeks]

+ad set The live videos are awesome! What's not to like? :-)

[@Moisesin]

Thanks for your time to produce this very informative and graphic photography class. Share your experience with us, is priceless

[@AtifAziz0077]

The best informative video on basics of photography.

[@kurtdasilvaofficial]

Really good stuff.. you guys lay it out so simply! And you hold nothing back! Thanks.

[@johnturnbull6116]

Well, that was simply the best, most detailed explanation I have ever viewed or heard. Think I am off to buy your book, all my old ones are being binned.

[@softwaretest1879]

Thanks for sharing Tony & Chelsea. You are doing an immaculate job! For the viewers, who would like to get to the main point of watching this video, like me, Jump directly to 4:26, where Tony and Chelsea tell you that each stop just mean double or half as much light hitting the sensor. For instance: ========================================================================== at f2.8, the amount of light hitting the camera sensor is twice as much as it does at f3..5. Similarly, at f2.8, the amount of light hitting camera sensor is half as much as it does at f1.8. ========================================================================== Thanks Tony and Chelsea for making it Simple for us to understand! Kind regards, Armaghan

[@williepadin]

One of the best videos I have ever seen. Super well done! Congrats

[@Places4u]

over the years I have learned a lot from you guys about photography so thank you so much for all the hard work

[@TonyAndChelsea]

+Joe Mcdad Thanks, and you're welcome!

[@Myselfakela]

Tony and Chelsea.... I've seen a lot of videos of yours but by far in terms of explanation this is the best of the best. Clearly in a laymans term. Thanks. Would love to see some more like this.

[@Woodenarrows]

Love your “Tips & Info” type videos. I started with 35mm film and SLR’s back in the early 70’s. I’m not a professional but I am an enthusiastic amateur photographer. I’m so glad I have the old school background as it gives me a through understanding of the things you are talking about here. I also understand the relationship of f/ stop to shutter speed. One of my early cameras did not have a light meter. I remember the f/16 rule for exposure (also known as the sunny 16 rule). Sunny daylight exposures will be generally be good at f/16 & a shutter speed matching your ASA film speed. Example: With ASA 125 film, a good daylight exposure will be had at f/16 and 1/125 second. If I want to use a larger f/stop, I can increase my shutter speed, say F/8 at 1/500 sec shutter speed (2 stops larger aperture, 2 stops faster shutter speed) equals the same exposure value. BTW, I’m already subscribed, I’ve never used a DOF calculator and I don’t miss processing film :-)

[@parker2969]

Finally people who teach instead of me leaving just as confused when I first started like most videos, I'm Finally understanding. Thanks to the yall!

[@2divyanshu]

Simple ,lucid and easy to understand ,Thanks @Tony&Chelsea

[@abuuthman6676]

Wow! This tutorial on f-stop is just awesome. The most informative and comprehensive that I've come across. Bravo!!!

[@GangGr33nanarchist]

Never saw this video before. It helped reeducate me about F//stop use.

[@joeybillitteri6133]

This is why we all keep coming back. Great job, and very informative .

[@15lastone]

U guys are Real Professionals, thanks a lot

[@haldarfamilyvlogs]

I keep coming back and check out your videos, they are very helpful. Really thanks a ton for putting these up.

[@PostColorGear]

I like what you pointed out at the 8:50 minute mark. For the most part, with maybe ONE exception, when you buy a lens, you buy it for the next focal stop, stopped down. In other words, Buy a 1.4 lens? Expect it to be sharp at 2 or 2.8 and just a little soft at the 1.4. I've always thought of this when purchasing lenses, and I always tend to not shoot that wide anyway. Background blur is great, but not at the expense of lack of sharp subjects.

[@najsbajsmedmajs]

+The Post Color Blog (Dave's Tuts) That's kind of true, but there are still 2.8 lenses that are sharper at 2.8 than 1.4 and 1.8 lenses are at 2.8.

[@zhouye7647]

+The Post Color Blog (Dave's Tuts) sometimes you know you dont need too much sharpness, for example portrait.

[@marcdevries9027]

+The Post Color Blog (Dave's Tuts) I found it quite funny that Tony would use the 70-200 2.8 IS II L as example, because most people buy that lens for it's excellent performance wide open.

[@UniquePhotoandVideo]

+The Post Color Blog (Dave's Tuts) I agree with your statement. I also never use a lens wide open, unless the conditions absolutely require more light. I prefer to keep the iso low. When filming I keep my f-stop around f/5.6 or higher.

[@FinalManaTrigger]

+The Post Color Blog (Dave's Tuts) Some lenses are optimized for wide open performance, usually at the cost of greater diffraction at the other end of the f-stop range.

[@iKeto_gal]

I subscribed and just bought the book. This is my first hobby in my life and I'm almost 50. Your videos are truly helpful 👍🏻

[@blunterwun]

you guys are the best on KZbin. Thank you.!!!

[@fewclips]

i wish i had this video when i was studying the subject. the details, the demos, the explanations in such a short video - excellent work! best one of all video and texts on this topic that i've seen.

[@TheKnut]

Excellent video for beginners! I remember watching your video on Aperture and shutter speed which you did in the basement. I taught me so much. This is very good, too!

[@jacksonhawk4021]

Wow! You guys are crazy good. Just prior to watching this video I bookmarked an online depth of field calculator. Simple fix: bye bye. That doubling of numbers thing that Chelsea did -- totally love it. I *just* got your book and I can't wait to learn from you. Thank You for being so awesome!

[@grat2010]

Your explanations and demonstrations are terrific. I'm just learning and you guys will definitely be a part of the journey!

[@ronitsingh85]

very well done, LOVED the way you explained DOF f stops with live examples etc, way cool!!!

[@TonyAndChelsea]

+Ronit Singh Thanks!

[@ronitsingh85]

+Tony Northrup No problem, you guys rock!!! :-) I love your approach to photograph, equipment and criticism on the new stuff.

[@Potato-adept]

The best video of the channel. Nothing more to say.

[@pichochea]

I'm actually learning photography because of your videos, thank you so much.

[@TonyAndChelsea]

Great, glad to help!

[@egemenbalkan]

Amma müthiş video hazırlamışlar arkadaş. 12 dk'lık video için ne emek vermişler. Şimdi bunların kazandığı para son kuruşuna kadar helal. Böyle işler lazım insanlığa. Geyik değil.

[@amv7m]

I know this video is four years old but, you guys are awesome. Thanks for the useful info.

[@LSRC69]

Thanks Tony and Chelsea this video really helped me out a great deal.You guys are fantastic.📷👍📷👍📷

[@HappyHubris]

Just picked up your book; thank you so much for finally explaining f/stops in an intuitive way!

[@KirbyYoung]

You guys deserve more views and appreciation.

[@bird271828]

Chelsea, Tony, thank you for your educational videos. Even when I know the subject of your videos, I still enjoy watching you explain. I wish my college professors were more like you :-)

[@prathameshtade]

This is one of the best videos I have seen on this subject. I'll definitely recommend this one to my friends learning about photography.

[@dreamsidedominions]

I just realized I loved you so much guys.. and I've known you for only a week now. You're just incredible. Thank you. I'm buying your books :)

[@sumukhgb]

Best tutorial video for pure beginners and advanced amateurs. Thanks for teaching 😀😀👌👌

[@TonyAndChelsea]

+Sumukh Bharadwaj Our pleasure!

[@paulj2383]

Thank you for explaining the technical aspects of this topic

[@cadmus777]

Excellent new format guys, that was really well done. Nice work Justin!

[@Camilavalverde8]

At last, I found the explanation of the origin of the f scale, 1.4 being √2. Thank you thank you!! you spoke my language.

[@hectorsand6800]

As a beginner, this is the kind of video I've been looking for. Thank you!

[@flipgenyus]

You guys are awesome! It makes more sense to me when you explain it compared to when I read it in other books. I just picked up your book after watching this video.

[@nixxni3571]

This is such a helpful video ! Really easy to understand and great for beginners like me. Thank you so much !

[@jameswarden9136]

This video is so informative, I'm impressed! you guys are definitely my favourite photography KZbinrs.

[@captbuscemi]

You guys are legends. Such good summaries of these things, and especially like the practical tips you deliver. Keep it up!

[@NikolajLepka]

“Just take a few test shots” You digital photographers have it so good in that regard

[@shylacraig1858]

You guys are seriously amazing. I was so bored by the math but I couldn't stop watching and I learned so much. Thank you!

[@spoddie]

You obviously put a lot of work into this. The dynamic examples are fantastic, seeing DOF changes in real time. One thing you may have mentioned is that you don't see this looking through the view finder because the aperture you see is (typically) the largest available until you shoot, the camera closes the lens to the correct aperture when you shoot. Don't use DOF calculators? No, understand circle of confusion, then use DOF calculators.

[@brycewilson5300]

Great lesson even for a "long time photographer. never was convinced Hyper focus worked! Thank you.

[@SargsyanTigran]

This tutorial is a beautiful piece of art. Thank you.

[@jeffersononetwo]

Oh man - what a FANTSTIC video and awesome couple! You guys made this so clear ... and I tested like you said with a JBL speaker on my desk. Right on with my pocketable Fuji XF-10.

[@jasonelles6121]

I found that easy to follow and made sense! I have even taken notes so I can reference them at a later date!

[@djjohnson178]

Thanks really learn a lot off this video. Finally was able to put together what's going on with the math behind F/stops.

[@slickshott]

Yeah you two, I love your channel and content... Very professional! I just ordered your book from Amazon!
