:D Well done in getting a reply!

Social media has some use after all ;D

Just heard back from them and they still cannot pinpoint the light leak, guess we have to live with it.

**Update**

I was a bit pissed with the lack of replies from Lifepixel and their disinterest in the knowing cause of the issue (they should be concerned as it affects their business) so I decided to write on their Facebook wall, my message got deleted within an hour but their social media manager did contact me via message and forwarded my complaint to them and they started replying. Cheap trick to get their attention but it worked.

So now the update I got was that they did try on a number of Canon bodies and it appears to be a common issue, the streak is most likely caused by some internal IR light when using liveview but they are unable to locate the light and block / seal it.

Best bet is to not use liveview for long exposures or use liveview to focus, turn it off and then take the shot. Not intuitive but I'd rather do this than spoil the shot. 

I will update here as and when I get more information.

Cheers :)

Awesome guys, keep em coming :)

@EvilZeev228
For a minute I thought you captured a flying saucer in your first pic! The blue dome shape ;D

@dinsy
Love the contrast in your pic.

I am bummed I live in the sticks. No city-scapes and famous landmarks here .

Wait... wait - one of the first carousels in the USA is here and a church from the days of the whaling industry is still being used. I guess I will have to take some picts. I'll have to start a new forum - Semi-famous little town landmarks.

Which town is this? Would love to see photos mate, any would be fine :)

Good work fellas, keep em coming :)

Interesting thread, I guess when you're living near some sights there's no way around taking some pictures of them sooner or later.

Agreed, I am never inclined to go shoot these places, would much rather shoot some bugs or seascapes, but friends/family wanna go and once there what better way to kill time than to shoot ;)
I have to admit though, If I get a good clean shot I am happy I went :P

A lot more heat is generated during live view, not just from the backlight on the LCD, but the snsor gets warm as well.  If left on too long, and the camera is in a warm location, it will go into overheat shutdown.  Its also possible that components in the camera are drawing more power than normal, which makes them run hot.

Thanks mate, from dswtan pic, to me it looks like some source of light, his pics looks like light flare.

Hey guys, how you going!

Was out last week and got these 2 photos from a new location






And one from (last) Newyear eve's fireworks, this one's a stack from multiple 30sec exposures.
The blue lights at the bottom are from mobile/tablet junkies ;D



Critiques, ways to improve, suggestions are welcome and please feel free to jump in with your pics, more the merrier :)

Cheers

Hi g2.
I am sorry to hear they are dragging their heels, hopefully it is because they are trying to find out more for you!

I have always said that the measure of a business is not how they are when selling you their product / service, it is how they deal with a problem. The thing is when they have a basically reliable product they may not learn how to properly deal with any issues.

Cheers, Graham.

I wholeheartedly agree Graham.


Are you taking the photographs over some ancient indian burial ground?  Jus askin'  :D

Haha, never know! ;)

An update.

I contacted Lifepixel about the issue and they seem pretty clueless about it as well, they mentioned it could be an internal IR light source, enabled when live view is turned on.

Sad to say I am a bit underwhelmed with their replies, the first reply came in about 2 days (understandable, I had mailed them over the weekend) but after that I had to mail them thrice (in 7-8 days) to get a reply and it has been a further 2 days and no reply to my last mail.

I have sung praises for their service and communication when I had the conversion done, but I am very dissatisfied with how they have handled  communication this time.

If I hear anything else from them I will update here.

When the IR filter is removed, the camera sensor will pickup heat from inside the body.  There are various shields for light, and they must be carefully replaced.  I'd ask the company that did the work about a normal expectation.  They should have tested it after the conversion.

Will check with them.

By the looks of the images, it appears to be a light leak and not heat, especially dswtan image, though I could be wrong.

I have this, but my pattern is a more defined flare.

Mine's on a 5D2, also full spectrum (clear sensor filter) converted by Life Pixel. They may know more about this, since they've probably had comments on it over the years unless it's extremely rare (just you and I!). But I've not got around to reaching out to them, and I'm not at the point of complaining about it, since the simple workaround is just not to use Live View during astrophotography except for focusing.

You can see my posts on it from just a couple of weeks ago, with photos, here:
http://www.dpreview.com/forums/post/54257998
https://groups.yahoo.com/neo/groups/Infrared_Photography/conversations/topics/22481

Mine -- complete dark, same with no lens attached, only source of light must be within body -- 30s at 1600 ISO:


So appears to be a common issue after conversion.

I'll write them a mail over the weekend and see what they say, will update here once I have a reply from them.

Thanks guys for all the help.

Kinda looks like light spot from single directional source at narrow angle.
If you have IR/UV filter removed, then it could be IR radiation from some component inside the camera, something that belongs to screen circuitry. Sometimes voltage stabilisers or voltage reference are made with LED sources.

If it's 600D, then I find it unlikely to be screen itself - screen is articulated and separated.

*I guess there is no IR detector below VF*

Hi KacperP,

The UV/IR cut filter has been removed from the camera, it could be, as you say, something with the screen circuitry but the screen is on even when using the VF and goes off when taking a shot in both LV and VF.

One question, would the sensor heat up by the same amount whether ISO 100 or 3200 is used? I assume higher ISO will just amplify the signal stronger or would the sensor emit more heat as well?

Thanks.

Do you see the artifact when you capture the LV image first after the camera has been off for a while?  The issue might not be light, but heat.  It looks like 'amp glow' but that's usually in a corner. 

Have you tried contacting the company that did the spectrum conversion (assuming you didn't DIY)?

Hi neuroanatomist,

The conversion was done by lifepixel around 2 years back, I only noticed the issue last week, I usually stick to ISO 100 for most of my shots but we went out for star trails this past Saturday and I bumped up the ISO and noticed this, I had seen it in ISO 100 shots sometime back but only when the exposures were really long (4-5mins+) and assumed it was heat from the sensor due to the long exposure.

The issue is present whether the camera has been off or in use for a while.

I am wondering whether it is heat as I tried a 30sec exposure in LV and the steak was there and then turned off LV and did a 2min exposure and it wasn't.

Thanks for your reply.
