Auto Lighting Optimizer - Changes shutter speed in manual?

Hi, I have a question regarding ALO. I recently enabled it on my 1DX and have since noticed my shutter speed will automatically change slightly once in awhile (while shooting in manual with auto ISO.) For example: I set my shutter speed to1/60 and it will occassionally drop to 1/50 and then jump back to 1/60. I've checked the instructions but couldn't find anything regarding this. It only happens with ALO enabled.
Cheers

Doh...you're right no safety shift in M mode...my bad...
I have no clue...I don't use ALO. I don't have the 1DX but on my 5DIII in M mode, I could've sworn I've seen the shutter speed flutter a few times...that's why I was so sure it was the safety shift feature...I only confirmed today that there's not supposed to be a safety shift in M.
I'll have to watch for this again...it might be something else because I don't use ALO.

How do I set the Shutter Speed in Manual Mode on my EOS 70D

I recently was forced to upgrade to a Canon 70D after my 50D died from a fall. I am not happy with the ease of setting the Shutter speed while in Manual mode. The only way I can currently set the shutter speed while in Manual mode, is to go to the info screen and set the shutter speed with the touch screen. The manual states that I should be able to set the Shutter speed with the Main Dial, behind the shutter release. ( which is how it was on the 50D). I can control the Aperture with the quick control dial. The Function Lock button is off.
I am sure this is do to some setting I have wrong, that is not allowing me to fix this issue, but I cant figure out what it could be after hours on the net and in the manual. I would greatly appreciate it if someone could help me with this issue.
Thanks
Gene

Another possible solution is to use a battery grip on your 70D and see if the dial on the grip will change the shutter speed.
There are some discussions about this problem on some earlier models Canon DSLR. Check it out.

Canon SX600 HS How do i change the shutter speed? Thanks

I need to change the shutter speed but manual is confusing
Solved!
Go to Solution.

If you need to change the shutter speed for a long exposure shot, you will need to be in the specific scene mode of the camera and choose the Long shutter mode. Then you can select a shutter speed. You cannot choose a shutter speed in other modes with that camera.

Canon 5D3 Feature Request / Wish -- Manual exposure auto shutter speed toggle

I've been using Canon gear the last six years & I don't know if this is currently possible in any camera body. If not, I believe it would prove highly helpful for working professionals.
When working in time-sensitive situations, I find myself frequently forced to use Av mode when I would prefer to remain in Manual exposure. Additionally, I find myself slowed down within Manual exposure mode when moving between inddor and outdoor light and/or other situations of dramatic ambient light fluctuation.
My wish would be for a menu assignment function for the "multi-function" button (next to the shutter release). Pressing the button while in M exposure mode would then set the shutter speed (like in Av mode--and another option could emulate Tv mode), and releasing the button would resume normal M exposure mode usage.
Personally, this is my biggest wish for the 5D3, and I would LOVE to see it implemented. (My second wish would be for the flash exposure lock to set the exposure of Flashes which are otherwise set to manual flash exposure, but that's another story).
Thanks,
Bert

Nope. That's a 1D X feature.

Suggestion - 5D3 minimum shutter speed for auto ISO

Hi, I would like to make a suggestion to Canon on the 5D3 camera, with regard to the minimum shutter speed for auto ISO. Currently I find that most of the selectable shutter speeds are on the low side (mostly below 1/125), and this may not be useful for handheld photography, or for fast moving subjects. I would like to suggest the following:
- More minimum shutter speed settings faster than 1/125 including in-between speeds e.g. 1/160 (between 1/125 and 1/250)
- Automatic shutter speed based on a multiple of lens focal length e.g. 2x lens focal length (for both prime and zoom lenses)
I hope that Canon can come up with an updated firmware that does this. Thanks.

Good idea, you can add it to the thread "Firmware Update Wishlist", and "Canon dSLR Wish List?" because a proper, configurable, flexible auto ISO is much needed and would beneficiate all cameras, not only 5D3.
I am not sure what Magic Lantern can give you on that issue, but you can take a look at their page.
Now, as a short term solution, on 1D4 I have put the cfns for 'shutter speed range' and 'iso speed range' in MyMenu, and when I need I change the max ISO (usually 1600) and a min shutter seepd (depends on lens and subject) on the fly. Not very practical (many button push needed), but it works.
I hope that helps

Add shutter speed settings and manual focus in the manual mode, please sony :'(

I am so deeply craving for shutter speed settings in the manual mode so I can take very great night shots.
Manual and infinity focus would be nice as well

First of all: I competely agree. Low light shots where anything you are photographing is moving = very bad blur.
Second of all: whilst I don't think it's right that you should have to pay money on top of a flagship device to get the camera working as you expect, there are a couple of this party apps will help until Sony fix this. Camera FV5 has a lot more settings including AE-L (in focus modes) which stops some of the post processing that can mess up low light shots. But be prepared the high volume of settings to play with also makes it less accessible as an all purpose point and shoot app. Camera Zoom FX is somewhere between this app and the stock appin terms of usability and functionality if you want to try that too.

Shutter speed changes.

Hi all,
I'm using a Nikon D5000 with Lightroom 3 and a Macbookpro. I'm new to tethered capture but I have "Lightroom 3 book fo Digital Photographers". After searching through that and looking through Adobe Help documents I have yet to find an answer to why Lightroom is changing my shutter speed. My camera is set to manual, shouldn't Lightroom be as well?
My happy ending in all this will be if I can find some way to keep Lightroom from changing my shutter speed.
Thanks in advance.

Hi,
You aren't using Mac OS X 10.6, are you? Adobe don't officially support it yet, although it may work, as per this quote from their tethered shooting support guide;
"Windows 7, Windows Vista, and Mac OS X 10.6 are not officially supported for the D3x, D90, and D5000, but they still may work."

6D shutter speed changes?????

Hi everyone, I am new here and if this question has been asked previously please point me to the post. I did browse through the previous questions but did not see this particular problem.
My probles lies with my 6D I shoot automobile racing with a 70-200 2.8 and a 580EXII flash, A couple weeks back during the night I was shooting manual mode and I noticed that my shutter speed kept changing on it's own, so I switched to TV mode and it worked fine for one week, but I noticed last night it started doing the same thing. I am setting my speed at 400 and repeatedly it would change to 200 or even lower, thus making my shots overexposed. Anyone have any ideas as to why this is happening??

I noticed the same thing when I used to have and use a 5D, 5D Mk II and my 7D. But since I went all 1 series I have not had it happen since. I still believe it is the knobs moving, rubbing, or something else moving them.
This was a big concern with the pros so Canon changed the way a 5D Mk III works so it can not move accidently.
The shutter wheel doesn't work any differently on a 5D3. It's the mode dial that now can't be turned accidentally.

How to force a shutter speed on footage that strobes due to LED lighting?

I shot some footage of a speaker against a projected backdrop that had LED lights and didn't have time to find the right shutter speed before it actually started. So now the background strobes quite frequently random colors due to them being out of sync. During the break I found that 1/60th of a second shutter speed evened it out enough to be watchable. So part 2 is okay but part 1 is horrible. I've already tried a slew of plugs in FCP and am stuck. I shot some burlesque footage a while back that had this same issue but turned it into old aged film and you can't tell. But this is for a client that kind of needs this to be clear for training. Help please! I know Shake has the power to do this, but not sure where the tool is...???

The best way to deal with stuff like this is to be creative with it. I'm sure some of the regulars to this forum have heard this story many times before but I'm going to tell it again anyway. I was working on a movie in Seattle that was shot on 35mm. We'd shoot one day and get the telecined tapes back the next day (or the day after if there were a lot). The last day of shooting came along, and the crew packed up and left for LA the next morning, with the post guys staying in Seattle to continue the edit. We got that last tape back after they'd left and guess what? One of the camera angles in a conversation scene was completely out of focus. The other guy was fine but every shot of the main character was unusable. Everyone had left - there was no way we could reshoot it, so we put our thinking caps on and ended up cutting in the good angle as a flashback during another scene. The result was awesome and far more powerful than the original scene would have been, and we'd never have found it if that angle hadn't been out of focus. I want to shake that AC by the hand if I ever see him again.
So try to think of a creative way around the problem and it could end up being even better.

Manual shutter speed Lolipop?!

Hi
In stock google lolipop manual camera controls like manual shutter speed is enabled.
But from what i can see, sony has not used that in their variant of lolipop.
Is there a reason for this?
I was gladly looking forward to taking long exposure photographs with lolipop, but it seems i won´t be able to.
Anyone know more about this decision?
Thanks
AD

I agree with you, I've been waiting for this option since back on the Xperia X10

Set manual shutter speed for long exposure photographs

To my suprise, i can not manually set the shutterspeed of the camera (a big disapoinment from iphone which can do this and i had before) i want to photograph waterfalls and create dreamy scenes.
4.3 did not fix this, anyone know if 4.4 update will adress this?
Is the problem with Sony or Android, since there are NO apps on google play that support long exposure in full resolution.
Anyone?

While we get an answer, perhaps understanding shutter speed will be a good idea for those who doesn't know how it works

What shutter speed to use for 1080i60 HDV?

I shoot with an HDR-FX1. The default setting is 1/60s. I could really use the extra light provided by 1/30, given how much the 35mm lens adapter eats up.
The HDV is 29.97fps, so 1/30 would seem the best choice anyway, but being interlaced, it’s really 60 half-frames...
Will using the 1/30 affect the image quality, the way undercranking or overcranking shutter on purpose would?
Thank you,
MaW

You get more blur, but the only way to really find out is to shoot some test video to how YOU perceive the differences.
Go to a darker setting about which you are concerned, shoot some in automatic shutter (it will go no lower than 1/60th in 1080i60 (progressive scan OFF)). Either have moving objects or move the camera around. Then switch to not-auto (probably need the IRIS set to IRIS mode so you can manually set iris, gain, and shutter speed). Let the iris and gain set automatically, and just set the shutter to 1/30th (whatever) and shoot the same scenes in the same lighting conditions.
Drag 'em both into FCP and see what you like. Too much blur? No effect?
Note that if you shoot in Progressive Scan 30 (that's 30p), the shutter will automatically go to as low as 1/30th.

The way to alter the shutter speed is to change the light sensitivity options but you only have four settings.

Raise Min Shutter Speed above 1/250th on 6D?

Hi All,
I just upgraded from the 20D to the 6D, and wanted to know, if its possible to set the min shutter speed above 1/250th of a sec on the 6D? If so, how? I wanted to know if I can set it above 1/640th or higher.
Thanks,

Hi Skirball,
You are correct! The reason why I want it near 1/800 is because I plan on shooting indoor sports with no flash, for the first time with this camera, and wanted to see if I can manually set my shutter to 1/1000th of sec as a min, and have my ISO set to auto. I normaly shoot in Manual mode.
I'd just use manual then, with Auto ISO. Using Av won't offer much benefit, unless you're shooting in a highly dynamic lighting situation, or you really need to fine tune with exposure compensation. Set your aperature and minimum acceptable shutter speed and just keep an eye on your ISO. If it's getting below 400 or so then bump your shutter up.
I never used auto ISO until I got a 6D. But the range of acceptible ISO is so good that it gives me a wide enough range for an "auto" experience. My only complaint is that there isn't an exposure compensation for auto ISO in manual.

EOS 70D : Slow shutter speed when LCD screen turned on

Hi !
Need your help. I am beginner & I have new 70D camera. When LCD panel turned off, the shutter speed is quite fast. When I turn on LCD Panel, the shutter speed automatically slows down & sounds annoying. The pictures are same in both cases. Also, the high speed continuous photo shoot, the shutter speed slows down when the LCD panel is turned on. Please help me to fix this.
Solved!

There is nothing wrong with your camera. It is working as it should when using LiveView.
There are two different types of Auto Focus:
1) Normally with a Film SLR or Digital SLR, you look through the optical viewfinder and view your scene through the lens of the camera. Behind the lens a mirror reflects the image up into the optical viewfinder. When using the viewfinder the camera uses "Phase Detection" Auto Focus. With PD AF the image passes through a transparent part of the mirror to PD AF sensors below the mirror. When you half press the shutter button the AF operates and when you fully press the shutter button the mirror flips up out of the way to allow the image to reach the image sensor behind the now open shutter curtain. While the mirror is flipped up, you can not see anything through the optical viewfinder. This all takes place very quickly and makes a fair bit of noise from the action of the mirror flipping back and forth and the shutter curtain opening and closing.
2) When using LiveView on a DSLR, the rear LCD image displays the image. In order to for this to happen the mirror must be flipped up and the shutter curtain must be fully open. The optical viewfinder becomes useless and the only way to see anything is by looking at the rear LCD screen. Auto Focus is no longer done with Phase Detection sensors below the mirror and now used Contrast Detection Auto Focus is used by reading the focus right off the image sensor. This type of AF is slower than PD AF.
The difference in sound is only because the mirror is already flipped up as soon as you press the LiveView button and all you hear is the sound of the shutter curtain clsoing and then opening up again so you can once again see the image on the LCD screen . The actual shutter opening and closing speed is exactly the same.
Here is more info on how Phase Detection AF works:
