6D Auto ISO caps at ISO 400 in 'A' mode w/ flash attached
6D w/ 600EX-RT and 24-70 F/2.8L II
Hi all!
I'm very sorry if this is a stupid question. I have searched the manuals for the camera and flash to no avail.
When the camera is in aperture priority mode, flash attached (hot shoe only, no slaves), and with ISO set to auto, it seems to cap at ISO 400. If I switch to Program Auto or take off the flash, it will go up to ISO 1600 as I've configured in the ISO speed settings in the menu.
I'm sure it's probably following a setting I've inadvertently set somewhere but I'm not sure where or what.
Any help would be greatly appreciated! Thank you!

Pictures taken with my 1D Mark IV show a blue horizontal line at the bottom from ISO 400 onwards.
Pictures taken with my 1D Mark IV show a blue horizontal line at the bottom from ISO 400 onwards. So far nobody has been able tot tell me the cause of this problem. The body is still quite new (15000 pics taken).
I agree that it looks like a column of photosites is not working. But... I'm curious as to why this would only happen at ISO 400 or above.
The sensor is covered with photosites -- they are monochrome. On top of the photosites is the "bayer mask". The mask is a checkboard pattern of red, green, and blue "lenses" which makes the photosite beneath only sensitive to that particular color. They are group in clusters of 4 photosites in a 2x2 matrix. Two of the four squares (in opposing corners) are green. One corner is red. One corner is blue. If you were to lose a column which happens to be along the red/green column (as opposed to the green/blue) then you'd lose red sensitive and half the green sensitivity in that column. The result would be that this column is flanked by two "working" columns which are full of green/blue photosites... hence the teal blue look.
I do not know if this will work for you, but oddly... you can actually sometimes "clear" stuck pixels (but usually this is an indvidiual stuck pixel... not a whole column of them) by putting the camera into manual sensor cleaning mode (and you may have to do this 2 or three times). While the normal point of the self-cleaning mode is to flip up the reflex mirror and open the shutter so that you can inspect and clean the sensor (really the front-most filter because you can't actually touch the real sensor), it also neutralizes the charge on the sensor (or so I've read). This charging and discharging of the sensor a few times can often get "stuck" pixels to start working again. BUT AGAIN... I've only ever seen this used on individual stuck pixels... never a whole row.

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

Dark pictures with canon 5d mark 3 and 600ex flash, night indoors in Auto Mode and flash on.
I have purchased a new canon 5d mark 3 and speedlight 600ex-rt flash. While testing it indoor at night , the room lights are on and I was using the Auto Mode with Flash on. The pictures are Dark with the Flash on and when the flash is turned off the pictures are brighter. I am confused. How to get the AUto mode working with the Flash on.
Automatic mode, it it's attempt to be reasonably foolproof, is going to lock you out of having any control over the exposure.
The E-TTL metering system on your camera & flash are attempting to find the correct exposure for your subject.
Due to laws of physics (the inverse-square law), light has "fall off". It's not actually possible to use a single light source and expose a large room with that single light. Either the subject is nicely lit but everything else will probably be too dark. OR... the background is nicely lit but the subject is heavily over-exposed. (BTW, there are two ways to get around this.)
The amount of fall-off is based on the relative distance from the light. Every time the distance increases by a factor of 1.4 the amount of light is cut in half. This means if you have subject 10' away, but you have a foreground object only 7' away and a background object 14' away, and the flash is exposed for the subject at 10', then the foreground object will be over-exposed (with twice as much light as needed) and the background will be under-exposed (with half as much libght as needed.) Incidentally... if you "double" or "halve" the distance then the light difference will be 4x or 1/4 (depending on if you are getting closer or farther.)
Here's a video which both explains and then later demonstrates the concept in a way that makes it very obvious to see and easy to understand. If it seems confusing at first... stick with it. The video is only 12 minutes long.
In fully automatic mode the camera wont let you control anything (except how far away you stand from your subject).
If you switch to "Program" mode, it essentially works like automatic mode EXCEPT it will actually allow you to override settings or set compensations.
When you use a flash in a room with some ambient lighting (but otherwise dimly lit) there's a technique called 'dragging the shutter' (which the camera can actually do for you somewhat automatically).
To do that, set the camera to Tv mode (Tv = Time value... which is shutter priority mode). Dial in a slow-ish shutter speed... say around 1/60th of a second. Use a moderately boosted ISO (400 would probably work well... you might even go up higher).
The camera is going to evaluate the exposure needed for the room as though you don't have a flash... and it'll set the camera settings accordingly. However... since it knows you have a flash, it'll still perform the E-TTL II exposure metering and will use the flash anyway. What you end up with is a shot that has a nicely exposed primary subject (because the camera used flash) AND... a nicely exposed background which was primarily illuminated with ambient light -- but looks pretty good because the camera used an exposure that was adequate for the ambient light.
The reason I suggest using Tv mode and NOT Av mode is because you can control the mixture of flash vs. ambient light by controlling the TIME that the shutter is open. But this does NOT work if you control either the aperture or ISO.
Here's why: The flash is "momentary" but the ambient is constant. If you were to adjust the aperture settings, that will increase or decrease ALL the light sources that contribute to the exposure... so it increases (or decreases) the amount of flash AND the amount of ambient light ... and it does them in the same proportions. If you want to bright up the background lighting WITHOUT over-exposing your foreground subject, then you don't want to increase both... you only want to increase the amount of ambient light.
Since the flash is a momentary burst of light, if you leave shutter open longer you wont actually collect any more light from the flash (because the flash was providing illumination for only a tiny fraction of a second. Extending the amount of time that the shutter remains open means the camera will _only_ collect more of the ambient light... and that helps bring up the dark backgrounds.
One way to get around the flash fall-off problem is to greatly increase the distance between flash and subject. You still get "fall off" but now the distance you have to change to notice the fall off really increases. But this method usually isn't very practical because you'll be standing much farther then you'd prefer to be to get the shot.
The second way (and much more practical) is to "drag the shutter" (deliberately use longer shutter times so that the camera can collect more ambient light long after the flash is done.).

(Chrome Like) Auto-Hide Tab bar in Safari Full Screen mode
Is there a plugin or some other way to auto hide the tab bar in Safari fullscreen mode like the way Chrome does?
This is the only thing stopping me from using Safari, it's way smoother than Chrome and feels much more native to Lion, but the fact the tab bar just keeps hanging there is annoying.
I tried the Cmd+I method mentioned in the community, but it only works when you're only opening one tab, if you open several tabs, the tab bar will show up again. It also comes back up once you exit Full Screen mode.
Thanks for your help !Hello myzzzl, this is normal behavior in full screen mode, you can set the [http://kb.mozillazine.org/Browser.fullscreen.autohide browser.fullscreen.autohide] in about:config to False, to change that, but if you do that tabs and location bar is enabled in full screen mode.
wait if another contributor/helper give you a code which I don't know.
thank you -
Bookmark bar is auto hidden in fullscreen mode, how to keep same functionality in normal mode out of full-screen?
In full-screen I just have the main toolbar showing, which is how I want it all the time. This or either make "full-screen" a lot better.Hmm, i think i phrased original question badly, i am looking for auto-hide to be featured in normal window mode as well as fullscreen, and whatever else designers and programmers can dream up and not execute poorly.
I have now disabled all EXTENSIONS and removed all 3rd party bars (google, sharethis, never used nayway;) and as my suspicions confirmed Safari is running much better. I was very suspicious of this when it was added as it seemed like trying to match Firefox, which I also gave up some time ago in place of Chrome as my second browser, although I use Safari for 90%. The extensions i think causes freezing when i had Parallels running a Windows VM at the same time and also other times when not.
The extensions is a bit stupid in my opinion as any niggling, minor feature of a website should be addresses to the website rather than the browser. Where adverts are concerned, well, just use the web less or more specifically!
I think I'm fine with Toolbar/URL-search and bookmark bar, its great - simple and not intrusive. I believe EXTENSIONS introduction gave me some sort of weird mental outlook and would urge Apple to be more careful in bringing in different types of features unnecessarily. -

Yes, it's normal behavior for the Voiceover function.
It's designed for the visually impaired. If it helps, try using your iPhone with your eyes closed. With the first tap, VO begins to read what is on the screen. When you hear the item that you want to select, tap the screen (anywhere) a second time. -
[TP Yoga S1] Windows 10 - Auto-Rotate button doesn't work in landscape mode.
I just updated to Win 10 on Yoga S1. A strange problem occured regarding auto rotate. When the laptop is in landscape mode (normal mode), the physical "Enable/Disable Autorotate" button doesn't work, and the Autorotate button in the action center button is disabled. However, when I physically rotate my laptop, the screen rotates, and suddenly, both buttons now are active. This defeats the purpose of the button since it can't lock rotation when the laptop is in landscape mode. Anyone having this problem too?

Hi! I salute you all!
First of all I want to excuse my english (it's not my native language)!
In 2014 we are dealing with thousands of files (video, audio, etc.), because of the present powerful technology, still... we are missing very important and useful parts for doing our jobs properly and very quickly!
In this case is Adobe Audition too, in my oppinion!
Adobe Audition is a great program, which help us to edit in many ways our audio files, but... unfortunatelly has major missing parts, which would be nice to be implemented as soon as possible!
Some of them are are right below this line:
1. AutoTrim (for removing silences from audio files, before and after)
2. Include Subfolders From A Folder (when adding a folder for working with, we should have the possibillity to add its subfolders too)
3. Preserve Subfolder Structure (when exporting a folder with its all subfolders, we should have the possibillity to export the exact structure like the original)
4. Auto Shut Down Computer (when all the tasks/jobs are done, we should be able to auto close the program and auto shut down our desktop/laptop as well)
When you will add these features which are so wanted, to have them all in Batch Processing mode and Match Volume mode as well, please?!
Many other audio softwares have all of these "old" possibillities, like "GoldWave" for instance (I am not advertising it at all), but the Adobe Audition which is more complex...doesn't so far!
I thank you all and I really wait for these very next future feature requests!
Have a nice day!

Auto Hide Panels when in survey/compare /loupe modes
As the topic states.
I may have a couple of panels open for basic file work (folder nav, keywords etc) When I get into culling images I like to have as much space as possible.
I would like the option for all panels to auto hide when I enter one of the mentioned modes. And then have them reopen (if I had them open) when I go back to grid view...Thanks Jeff. I am aware of those options. But for times sake I want to have the option to do it automatically. I have both my hands occupied, 1 on the mouse and it's 3 custom keys and the other on a Shuttle Express puck with my most used key strokes assigned to it. So going up to the keyboard to do this removes some of the fluidity. Also when tabbing the panels open and closed does it not open/close ALL 4 panels? I just want it to toggle what I have open which is normally Left panel and Film strip.
May be I am just being too lazy :)
Thanks again Jeff. -
Auto fill subject with an Email link in CS4 Bridge flash web gallery
Is there a way to autofill the subject line of the email link in the CS4 Bridge flab web galleries? I can do it if I use the html gallery, but I prefer the look of the flash galleries.
If I open the "group.xml" file I see code for me email link, exp.: <contactEmail>maillto:[email protected]</contactEmail>
I tried adding the "?subject=My Subject" like I would on an html file but that didn't work. I was hoping for some suggestions.
Thanks!I want it to work on the click of a mouse: when I run or test the page the email comes up immediately. Here is what I have so far:
navigateToURL(new URLRequest("mailto:mailto:[email protected]?subject=yoursubject&body=your message"));
/* Mouse Click Event
Clicking on the specified symbol instance executes a function in which you can add your own custom code.
Instructions:
1. Add your custom code on a new line after the line that says "// Start your custom code" below.
The code will execute when the symbol instance is clicked.
button_3.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_6);
function fl_MouseClickHandler_6(event:MouseEvent):void
// Start your custom code
// This example code displays the words "Mouse clicked" in the Output panel.
trace("Mouse clicked");
// End your custom code
So how do I get the email to open ONLY when the mouse clicks on the link??

Yes the supplied profile works - in my test shots it corrects distortion and vignetting nicely - but it is a pain to have to pick the proffile by hand for each shot.
My real issue is Lightroom not correctly identifying the lens and listing it as "Unknown" in the meta data. Was hoping there was a way to teach lightroom to recognize it - or a config file to hack to make it recognize the lens.
For testing puposes I changed the raw format of my Pentax from DNG to PEF but got the saame result.
Anyone else have ideas?

Can amount of NR be auto applied based on ISO?
ACR 6.1 trial.
Can the amount of noise reduction in ACR 6.1 change automatically, based on the ISO of the image?
I would think the amount of NR would be different for different ISO's (stronger for higher ISO's like 1600, less or none for ISO's like 100).
Do settings like Luminance 50/50/25 + Color 50/50 result in the same amount of NR at ISO 100 as ISO 1600?
Suppose I have thousands of images from a week long kids camp, shot at lots of different ISO's. I don't want to individually tweak each image for NR.
I've used the NeatImage 6.2 NR plug-in for CS4-64. It seems to work well, and uses EXIF to determine the ISO, and uses different profiles based on the ISO in use. Can ACR 6.1 do something equivalent?
My impression is that NR in ACR 6.1 has a definite advantage over NR plug-ins in that it seems to do NR at an earlier stage in the processing pipeline, probably before any capture sharpening, clarity, etc.
Or should I group the images based on ISO, and process differently, like "Low NR" for ISO 100-200, "Medium NR" for ISO 400-800, and "High NR" for ISO's over 1600?The NR in ACR is sensitive to ISO; my default is set to Luminance=20, Luminance Detail=50, Color=25, Color Detail=50. These settings have little or no effect upon low ISO images, but kick in some NR as ISO rises, with good results up to ISO 800 on my D300.
One can make the ACR defaults for a particular camera ISO sensitive, settable in the preferences. I haven't tried this, don't know how many ISO points are required and whether or not there is a rounding function. If this function is fairly "intelligent" one could create a half dozen or so NR defaults and ACR would apply the ones with an ISO nearest the actual image ISO.
All this being said, for more severe noise situations a third party Photoshoop plug-in is desirable, such as Noise Ninja, Denoise, etc. And as far as I can tell there is no disadvantage to using after the raw conversion, assuming all NR and sharpening is turned off in ACR.

Is there a way to apply noise reduction based on ISO value?
I shoot a lot of sports using auto ISO which means I get hundreds of images from a day with a variety of different ISO values, including all sorts of intermediate values (like ISO 280, for example). There are times when I'd like to apply LR noise reduction across the whole batch of images, but I'd like to apply it based on the ISO value of the image. For example at ISO 1250 and above, I want a particular NR Luminance value. From 640 to 1250, I want a different value. From 400-640, a different value. I know you can define some things at import time based on ISO, but that doesn't seem practical when the ISO value can be nearly anything as it would take hundreds of import profiles.
So, any ideas how to apply NR based on the ISO across a batch of images?jfriend0 wrote:
How do "defaults" interact with a preset applied upon import? I shoot RAW and apply a preset upon import for every import I do. If I apply a preset upon import will it override the "default" anyway? If that's the case, then defaults are of no use to me.
Yes - Lightroom presets are absolute, but unlike the default settings, presets don't have to specify all the settings. If a preset setting is specified, it will blindly overwrite the previous setting, if not specified then the previous value will remain unaltered.
DevAdjust supports relative presets: final-value = present-value +/- relative-preset-value

Illustrator Creative Cloud keeps freezing when I close a window
My company recently upgraded to Adobe Creative Cloud. Every time I close a window in illustrator the wheel comes up and freezes Illustrator for about 30 seconds. When I primarily work in Illustrator all day every day, this is an extremely long time.
