So is this the "white balance" issue everyone was talking about?

[Statusnone88]

I really didn't want to accept another problem but I'd like verification if this is the issue everyone was talking about and if so... is this every device or only some? (Pay no attention to the address, it's a UPS hub around where I'm located. Ironically enough I took this picture to remember where I could return my iPhone through the mail.)

Also sorry for the large images. Don't know how to add thumbnails with bbcode.

Yep.

It gets more and more intense under bright florescent lighting.

Same Phone.

Under Florescent lighting

Now same phone and piece of paper with incandescent lighting.

 

[pfft]

I give up, what am I looking at?

Edit: Oh I see. (I don't really).

 

[Wicked1]

If I take any photos near where I sit at work with the overhead lighting I get the blue like spots on my photos, however some of the other photos I took from a distance did not have the blue spot, but so far at home and outside I do not see the issue. I have chalked it up to the Flor bulbs at work and will try to stay away from them, this camera is still better then my 3GS and most of the other phones on the market, so I do not expect perfection all the time.

So is this a device-specific problem or are ALL iphone 4's having this issue? I know there's a HUGE thread around here somewhere.

Also I took that inside the UPS store, so I know they have florescent lighting.

Auto White balance on the most expensive of cameras is NEVER ACCURATE!!!

I own several DSLR's and I can tell you that .....

Florescent Lighting SUCKS for taking picture with ANY CAMERA

Also Mercury Vapor as well.

The reason for this is the lighting fluctuates 60 times per second, 50 times per second if you are in EUROPE.

I can make the best DSLR's on the market from any manufacturer look like what you are seeing by using Auto White Balance and Florescent Lighting.

This is NOT AN IPHONE PROBLEM !!!!!!

Do some research before you declare it an " iPhone Issue "

This is from the thread I posted the link to ....

Yep, your problem is the sodium vapor lights.

They turn on and off 100 times a second, twice the 50 Hertz rate of your power mains.

You have three choices: live with it, shoot flash, or shoot at a shutter speed of 1/100 second. That speed guarantees you get a full illumination half-cycle from the lights.

You can also shoot at 1/50 or 1/25, to get a full cycle or two cycles. But That's not much use for fast sports...

EDIT: This is also true for tube-type fluorescent lights, but not for compact fluorescents (they have a higher pulse rate). It's not true for incandescent lights because they stay hot and don't flash off and on with the power cycle.

Lighting is important in photography to achieve accurate White Balance.

If you are indoors with bad lighting, where it is uneven, odd color temp, pulsating you need to be able to overpower the ambient light with flash.

FLORESCENT LIGHTING IS EVIL FOR PHOTOGRAPHY !!!

Expecting a CELL PHONE to be able to do this is insane.

Buy a CAMERA !!!

Well I'm no expert but I went right under a florescent light in my apartment and this is the result I got:

 

[sleyeu]

i get it too, in my normal room light, and it is only visible on bright surfaces, such as this lovely piece of paper specimen

Shine your lens in the sun or a bright light, can u see a green/blue tint reflection? Damn u apfel.

edit: crapcrapcrapcrapcrap whats this purple crap around the blue!!?!?!?!?!?!?!? its a white peice of paper!!!!!! But my macs background is purple...


ok i can confirm it is my background, i tried this again and my screen went dark, the purple went away

 

[Statusnone88]

So wtf are these GREEN lines appearing now?

 

[harcosparky]

It's called BANDING

If you happen to click the shutter at the same time the light pulses off/on you will get crap like that.

 

[harcosparky]

ALSO .......

Your WHITE PAPER may not be so " white " photographically speaking.

Any photographer will know this ..... cell phone users ... not so much!


I have seen 'white' paper show up as gray, yellow, green and blue depending on the light and paper content.

I should have stated I took these WITH the flash on. The ones without the flash didn't end up like this.


I'm pretty sure the flash shouldnt be doing this to my pictures but then again I'm not photo expert.

Also I took about 15 pictures with and without flash. The ones with ALL ended up with green lines like above.

I am just saying that I am a photographer, and I know to avoid florescent lighting for any work where accurate color balance is require.

Use incandescent lighting, with a color temperature matching or close to the color temp Apple uses for the iPhone.

not as obvoius when flash is on...

I don't have the specs for the iPhone flash, but it's not all that powerful, of it were you'd be complaining about short battery life.

The flash is competing with ambient lighting and losing.

 

[Sleazy E]

oh no! how am i supposed to continue my Photos of Plain White Paper photography project now?!?

 

[harcosparky]

not as obvoius when flash is on...

the flash is helping to overcome the issue but not strong enough to take over as the primary light source.

 

[Statusnone88]

Actually my pictures are pretty horrible when my flash is on. The ones it takes with no flash are pretty good.

 

[harcosparky]

Sure, just make sure the white paper is ....

1) white
2) held parallel exactly to the image sensor plane
3) photographed under 100% balanced lighting of the right color temp

Wrong.

It is used all the time in the industry. Gives you a lot of light without the heat.

You can see some systems here.

Systems that try and use Auto White Balance though will have some issues though. That is always why it is best to manual adjust your white balance with something white.

I can make the best DSLR's on the market from any manufacturer look like what you are seeing by using Auto White Balance and Florescent Lighting.

Wrong again.

Incorrect white balance will affect the color of the entire photo, just not the middle like the iPhone is showing. Take your DSLR Camera, set it for incandescent and shot under florescent lighting and you entire picture will be green unlike the green spot in the middle of an iPhone picture.

BTW the link you posted to above talks about how florescent lighting effects exposure making something underexposed, not how it makes a circle in the middle of a different color.

Not trying to be a jerk. Just making sure that correct information is being passed on.

 

[harcosparky]

Like I said, I can make a $10,000 DSLR look bad trying to take a picture under piss poor lighting.

It's easier with a Cell Phone camera though!

 

[frosse]

Who the **** takes a photo of a blank piece of paper anyway?

 

[Statusnone88]

so livingonvideo13 are those green streaks a problem all iPhone 4's are having, or just certain ones in particular? Like I said, the pictures and videos with the flash OFF are great! It's when I turn the flash on that everything goes to *****.
