  • It's all relative. It's all in what you want. There is no definitive answer that the beginning photo is under exposed. It may be perfectly exposed for the intended use as a dark background scene. The best photography class is to go out and take thousands of pictures, tens of thousands of pictures, then choose one or two that you think turned out the way you like. Build from there, but keep on shooting.

  • jack002tuber, Hand holding your camera. A simple way you can look at it is: If your lens is at 50mm you will need at least 1/50 shutter speed. 70mm you will need at least 1/70 shutter speed. 100mm = 1/100 and so on. Using VR (Nikon, Vibration reduction) or IS (Canon, Image stabilization) will give you an an extra couple of stops to play with as well. So 100mm you can shoot as slow as 1/25 instead of 1/100. I wont confuse you too much with the difference between cropped and full frame sensors now. But if you are using a cropped sensor (which you probably are)...Multiply those numbers by 1.6 for Canon and 1.5 for Nikon.

  • Thanks .Clear explanation.if you add or decrease a stop then do the same to another parameter. I have another explanation with Algeria LHS = RHS keep ISO fixed Apperture = Shutter speed Eg 5.6 = 1/500 Decrease by one stop =Increase by one stop 4 = 1/250 And vise versa When we cannot go beyond F4 Then decrease or increase ISO and Shutter speed. For eg We cannot go beyond F4 The to decrease by one stop ISO go for ISO 50 and increase shutter speed by one stop ISO 50 =SS 1/500 Hope this helps

  • heres one simple basic guide to help u all... never reduce the shutter speed so as not to blur your pictures due to camera shake etc .. try not to go lower the 1/50 if you can help it.. shoot at average aperture of 5.6 or 4 or lower eg 3.5 or 2.8 if its getting dark (night) and if photo is still dark then bump up the iso till you get a pic you are happy with.. iso 200 or 400 or 800 or 1600 or 3200..keep bumping the iso up.. too high u may get bit grainy but at least u got a decent pic.. in the daytime iso 100 to 800 if needed should take care of most things..tip.. use av mode on camera..play with iso to get good shutter speed and exposure..this is just a basic guide which will improve your pics overnight..Hope it helps..Riz (Moments in time. by riz ali photography)

  • It's actually easy once you understand why. One stop down is half as much light, one stop up is twice as much light. If your more interested in aperture "More or less back ground seen in the photo" higher gives more back ground ie f22 or less f2.0 Shutter priority gives more control over contrast, motion "speed" and time film\sensor is exposed to light. You can fool the camera with EV + - settings as well. This only applies if the area of interest light is metered correctly. One reason light meters are a valuable tool as light comes from different spectrums not values.

  • Great video! One of the best pieces of advice I received on exposure was if the lighting is decent or better, is keep your camera in Auto ISO. Then based on what you're trying to accomplish you can choose to shoot in Aperature or Shutter Priority. This is similar to what you alluded to having to do in the days of Film.

  • The supposed under-exposure at the beginning is far more interesting than the "correct" exposure. The mystery and moodiness make you look longer at the image in a state of wonder and curiosity. It's an artistic concept called apophasis. It's fucking beautiful.

  • Forgetting that while all 3 variables controls the exposure they also each have a secondary function and/or trade off. Shutter speed means u either freeze motion or get motion blur, aperture is going to determine your DOF (as well as the focal length of lens) and ISO is going to make image clearer or more grainy. So when setting the exposure you have to sacrifice something. With shutter speed the work around is use a tripod or find a way to stabilize it. But say if you want to shoot at F1.8 but image is over exposed and you also wanna freeze motion but you also want a clear grain free image, it can't be done unless u have the ability to add loads of lights which is the alternative. Otherwise you're gonna have to sacrifice something. So you may have to increase aperture but you lose the bokeh that you might have wanted or you sacrifice shutter speed and retain that bokeh but you may have a problem with motion blur depending on the subject, or you can sacrifice ISO but will result in a grainy image.

  • I normally like to control 2 sides of the exposure triangle and let the camera control the 3rd. I usually have it in aperture priority with a manual ISO or manual mode with auto ISO. If it's looking too bright or too dark I use the exposure compensation. If I'm in daylight or on a tripod I will use aperture priority with ISO 100 because in daylight it might choose like 1/200 s or 1/600 s which doesn't really have any effect on what the photo looks like. If I'm using a tripod in low light and the subject is totally static then the shutter speed doesn't affect what the photo looks like. If I'm using it hand held in low light I will set the shutter to the longest I can hold it still for which is usually 1 / 35 mm equivalent focal length, set the desired aperture and let the camera decide the ISO.

Those who condemn this effort are the kind of people who vote for politicians because of excellence in another pursuit, an example would be voting for a retired athlete or because a campaigner wore a nice tie, or because the politician message is a nice catchy phrase.

    • Wait, I don't condemn this effort at all. I learned a lot. And I vote for people who do excel at outside ventures or businesses. Success is what I want in an elected official. Not a career politician. The art of negotiation is first learned in sports, team work or business ventures. I want my official strong enough not to take bribes or lean to another that can fatten them. So, your metaphor in my case doesn't fit. I love the bucket analogy and water flow, I actually think I grasped the principle of photography. And I would prefer quarter back, green beret, or CEO in office. Lets run things like team work, fighting force or a successful business. ; ) Deepest respect.

  • Very good video and def good points of explanation. Now my question is how do you know when you have "Correct exposure" when introducing a speedlight to your image. For example when I use the stock on camera flash I usually use my exposure meter to determine when I raise or lower a factor being iso, aperture, or shutter speed to compensate for the flash. Also when the flash pops up on my camera it shows that I will be over exposing or under exposing if i use the flash but when I use a speedlight it does not give me the same output. Anyone help please

  • I don't know what everyone is going on about. I thought this video was very helpful. I think it really depends on how people learn. For some people it may be beneficial to break it down through simple metaphors. I do wish there was a little more time spent on the math, but it's a fairly simple concept in the first place (meaning there's really not much to be said about it...in my opinion.)

    • Depending on your camera, you can just search the standard settings for starters. But it varies depending who you ask, and what type of photography you like to, such as portrait, landscape, street, nature, night, action, etc. For instance, most action or sports photography use fast shutter speed (mostly use 1/2000 shutter speed) Additionally, there are other factors you should consider such as lighting (Is too harsh or dark?) relative to your subject and background, or if you want to adjust the depth of any of the details, etc. That's the beauty of manual photography, it's complex yet fascinating.
