savan_thongvanh Posted September 29, 2008 Share Posted September 29, 2008 In the past I've shyed away from using the auto iso setting on my cameras for fear of getting a speed that was too noisy for my camera to handle. With cameras D300 and later it doesn't seem to be much of an issue, especially if you're using 2.8 or faster glass. Is it feasible now that we can just lock our cameras in (for the most part) @ auto iso, 1/125, and f/2.8 and let it rip? sounds lazy but i'd love to see some thoughts- Link to comment Share on other sites More sharing options...
marcphotography Posted September 29, 2008 Share Posted September 29, 2008 I Initially thought that I would use this feature alot on the upcoming 5d Mark II but I find that setting everything manually in constant lighting conditions yields to must more consistent results. I will most likely use the auto ISO feature more than AV or TV mode when I am in constantly changing lighting situations though (ex. partially coudy days) Link to comment Share on other sites More sharing options...
wpahnelas Posted September 29, 2008 Share Posted September 29, 2008 like everything else auto ISO has its uses, but i wouldn't consider it a "set it and forget it" option. it's no more appropriate than shooting in "P" mode all the time. Link to comment Share on other sites More sharing options...
michaelging Posted September 29, 2008 Share Posted September 29, 2008 To me, its a little like having your parents make all the decisions for you, when you are a child. They might believe that what they are doing for you is correct, but you might not feel the same way. The more you let something else think for you, the less control you have as a part of your creativity. Some, but not all auto features on cameras give you settings that are a compromise, this might be fine if photography is not a passion, but most of the people who are on this web site , I believe are looking for something more than just pushing a button and taking what the camera gives you. I might be wrong. Link to comment Share on other sites More sharing options...
starvy Posted September 29, 2008 Share Posted September 29, 2008 savant, it depends much on your style of shooting. if you are getting good results with the auto setup then there are no problems. if you are likely to be within the same sort of lighting situation then it matters little whether you are on auto or a manual setup. however, if you shoot in differing lighting environments a consistent yield can only be achieved through manual setting of iso.

savan_thongvanh Posted September 29, 2008 Author Share Posted September 29, 2008 I do more wedding photography than anything. I'm inclined to make photos w/ the least noise possible. Having said that if I can get acceptable noise levels at varying ISOs and I'm going to shoot 1/125 f/2.8 most of the time anyway, why not use auto iso? it's going to give me the lowest setting it can. I will still change these settings to suit my creative desire. And I think it's already been acknowledged that you can get a clean image out of a body >=d300 at almost any iso. If optimal iso for a photog = clean images, isn't that setting pretty objective? If it's objective why not let the cam decide, it should come up w/ the same thing as me right? I hope you can tell I'm trying to be devils advocate a bit but I am curious about the rationale. Link to comment Share on other sites More sharing options...
hans_janssen Posted September 29, 2008 Share Posted September 29, 2008 I use my iso-auto only when I am working in circumstances with low and changing light, concerts etc. I get sometimes isoos of 400 instead of the normally used 1600. I set the iso-auto at 1/(1.5)xf and to a maximum of 3200 and start fine-tuning the max iso to the lowest value. In normal conditions I never use the iso-auto option.

roman_thorn1 Posted September 29, 2008 Share Posted September 29, 2008 First of all, setting your camera to auto ISO will not limit your creativity. You still can control your DOF and composition. True, I don't think it is a "set it and forget it" setting. When capturing the moment is more important or your subject is moving around in changing light, auto ISO is very useful. However, when I'm just shooting for myself and time is not a factor, I'm in full manual. Link to comment Share on other sites More sharing options...
Peter_in_PA Posted September 29, 2008 Share Posted September 29, 2008 Every now and then, I have to snap something so quickly that I don't have time to think, or I hand my camera off to somebody who doesn't know how to use it. In those cases I use the green auto mode and I am always amazed by how good stuff comes out! Link to comment Share on other sites More sharing options...
Ed_Ingold Posted September 29, 2008 Share Posted September 29, 2008 Auto ISO is a feature on my cameras, but one I have never used. I've never used (P)rofessonal mode either, but I'm not forgetting that these features are there. I prefer to be in control of those parameters which affect image quality the most - aperture and ISO. If consistency is paramount, as for portraits and group photos, I use manual mode for everything, including focus. On the other hand, if you shoot only for yourself, who's gonna' complain :-) Link to comment Share on other sites More sharing options...
ctirpak Posted September 29, 2008 Share Posted September 29, 2008 Love the feature especially when photographing sports in changing light conditions. I don't always us it but sometimes it is handy. Link to comment Share on other sites More sharing options...
lightsmith1 Posted September 29, 2008 Share Posted September 29, 2008 I photograph weddings and environmental portraits and for both situations the Auto ISO with the D3/D300 is great. When shooting the ceremony inside the church and the recessional with the B&G exiting the church the Auto ISO will drop the ISO and I can keep on shooting without missing a beat. Without that I would be changing my ISO setting and my aperture and missing key images during the process. I shot an engagement session yesterday and was going from shade to sunlight to shade and using fill flash. I prefer to shoot during the last hour or two of daylight so the ambient light level is changing almost minute to minute and the amount of fill flash needed needs to be adjusted for each location depending upon the ambient light level and whether their is strong back lighting and reflected light striking the couple. Auto ISO simplifies the process so I can adjust just the flash EV and using AP have the camera virtually on full auto. The more I have to adjust the camera the more the flow is broken when I am working with a couple. But I am using auto ISO with the max ISO capped at ISO 1600 where I know I will get usable images in terms of noise. I wish there as a ISO 2500 max setting available as this is my true limit with the D300, but ISO 1600 works well enough and I can manually override the auto limit and adjust the ISO to 2500 when necessary.

savan_thongvanh Posted September 29, 2008 Author Share Posted September 29, 2008 wow, that was compelling! it sounded like an ad but actually made sense. I may sound like I'm a huge proponent but I use a d2x and probably get very little benefit from auto iso as I only have 100% confidence up to iso800...

CharlesBecker-Toronto Posted September 29, 2008 Share Posted September 29, 2008 Will auto ISO automatically select the lowest ISO setting that will give the correct exposure? I have never used this feature before,in part, because I don't know the answer to the question. I just bought the Nikon D90 (and love it so far) and wouldn't mind trying it out if I can depend on getting the lowest possible setting that will do the job. In the meantime, I use ISO 200. Thanks for any info! cb Link to comment Share on other sites More sharing options...
savan_thongvanh Posted September 29, 2008 Author Share Posted September 29, 2008 Charles, <br/>that's the idea, speaking from a nikon perspective. You set the minimum and max iso and the camera goes up in increments from the minimum. If the maximum iso is still not enough to get the proper exposure it starts slowing down the shutter. That last bit may be something people don't like... Link to comment Share on other sites More sharing options...

Sanford Posted September 29, 2008 Share Posted September 29, 2008 The problem with auto ISO the way it's implemented by Nikon is that it also seems to insinuate into the manual exposure mode, which makes things truly confusing. Link to comment Share on other sites More sharing options...
photo5 Posted September 29, 2008 Share Posted September 29, 2008 I began using Auto ISO recently and I'll never stop using it. It is a big time saver. Basically it uses the lowest ISO possible with the lowest shutter speed you specify. For example, I set 1/15 sec shutter speed, as I can hand hold that pretty reliably with VR on. I set the max ISO to 3200 on my Nikon D300. It's quite simple and works perfectly for me. Link to comment Share on other sites More sharing options...
bruce_margolis Posted September 29, 2008 Share Posted September 29, 2008 For shooting during the day, I generally leave ISO Auto on for the D300. Depending on the lens, I may have a minimum shutter speed set at 1/60 or 1/125 so there may be some daylight shots at the ISO max 1600 setting. Also, I leave it on for fast action where a shutter speed of at least 1/1000 is necessary. However, for sunrise/sunset stuff or most anything else with a tripod (like some night shots) or long exposure, I turn off the ISO Auto. Link to comment Share on other sites More sharing options...

robert gordon Posted September 29, 2008 Share Posted September 29, 2008 I'd love it if my Nikon D 300 had a tripod-f/11 setting that would set the ISO to 100, the aperture to f/11, the exposure mode to aperture priority, the focus to hyperfocal for whatever lens I'm using (usually a 20mm) and bracketing on with bracketing set to three exposures at one stop intervals.

Rene11664880918 Posted September 29, 2008 Share Posted September 29, 2008 When there is enough lighting (during the day) I keep mine on auto ISO, that is coz If i use small apertures and then to large apertures I don't want to be bother with all that. If there is enough light the noise is not that visible. As soon as the lights go down, I go back to ISO 200 and let the tripod do its job. Link to comment Share on other sites More sharing options...
Apurva Madia Posted September 29, 2008 Share Posted September 29, 2008 Even now I use auto ISO when light is too less or if there is hardly any time to think about exposure. The results are acceptable as against not getting the shot at all. Link to comment Share on other sites More sharing options...
