Camera Issue?
Submitted by Adam Gallash on Sat, 2009-10-31 22:16
Hi Crew,
I recently got a Canon 50d with the 18-200 lens, anyway, I've been taking a few pics and have been getting a black line on the left hand side of the image. The wierd thing is, I will do it and a couple of photos will be fine, then the next couple will have the line, then the next few will be fine again. Its got me really confused. I've checked the lenses and everything and its all good, well, if other pics are fine then I'm not sure whats going on. After only having it a week or so, I don't want to send it back just yet, thought I would suss if anyone has had similar problems with their cameras before?
Cheers,
Adam

it could be something like a hair inside the lense,thats what it looks like anyway, if so i would say when the shutter moves the hair would move with it so its not always there

no cord
No cord for these lenses, just a cap. And no hair apparent, I've given it a clean but I can't seem to see it and its not obvious, unless it is inside the lens or something??

Could be a hair on your sensor, remove the lens, lock the mirror up and have a look.
be careful removing it and make sure you are in a dust free environment
the mirror might be moving it back and forth, worth a look inside, cant be a lens problem or it would show up on all shots and canon lens are built so it's virtually impossible for a hair to enter, the hair might be statically clinging to the back of the mirror so have a really good look in there.
Tip: never shave, cut your hair or pluck nose hair over a DSLR whilst the lens is removed :)

yep
Yeh, its definately not the lens. I've read through the manual and it says you can go into manual sensor cleaning mode - but I've gone through the menu and I only have automatic. :( I really don't want to start playing with the mirrors though, it does appear that the 'hair' has moved from the left side to the middle right. I've tried blowing it out of there with the little air puffer provided in the cleaning kit, but I think your right in it being statically attached. I really dont want to have to send it back under warranty or get it cleaned professionally (mail charges etc) as I really need it in about 3 weeks and I know that I will not get it back before then. :(((Sigh

could be a dirty sensor
could be a dirty sensor mate
your camera has a built in sensor cleaning function, this usually is a vibratoe that "shakes" any dust off the sensor. If it appears then it is possible that the sensor cleaning function built in to the camera is cleaning it but the same Stuborn piece is comming back on to the sensor. I would get it cleaned by a camera shop even if that means sending it away mate. You can pay for kits to DIY but i would send it to some one that really knows their stuff

I'd go for a fibre on the sensor..
Occasionaly I'll get fibres off my strap find their way onto the sensor..
Because of the magnification the tiny fibres look huge when seen on your image !
On one occassion the fibre looked like a short and curly !! Took sometime to locate but once gone, all was good.
You'll most likely find static is keeping it in place..
If you have a hand held blower brush, remove the brush, read you instructions on sensor cleaning (as you will need to keep your mirror up), remove the lens or body cap, get into sensor cleaning mode and while holding the camera with sensor facing down use the blower and give a couple of puffs.... NOTE !!! DO NOT insert the blower any deeper inside the camera body than the lens mount !!!!
Or failing that, find someone in Exmouth who might have a Sensor loupe and Visible Dust Sensor Brush Kit... The loupe will help locate the fibre, the brush gets a slight static charge that will pick up the fibre... problem solved !
Or if you happen to be in Perth in the next week or so, give me a call..
Just be carefull when changing lenses, where possible turn the power of the camera to off in order to reduce static charge and keep the body either facing down or away from the wind while swapping lenses.
cheers,
Paul

sent off
Decided just to send it off to NSW, cost me $17 registered and express. Not too bad. They said if I put on a date that I wanted it back by they would try and do it. Should hopefully not be a problem.
Strangely enough, I went to do the manual sensor clean and that option doesn't exist on my camera, even though its in the instruction book and the canon guy I spoke to said it doesn't happen. Unless I'm being retarded and missing something?

simply amazing!
You managed to snap a pic of your DSLR with your DSLR. My guess is some kind of trick photography - but how??

A good test to check your sensor for dust is to take a shot of a white wall or blue sky at the cameras smallest aperture (say...f22) and black spots should show up where the dust is

aperature
How do you determine which aperature is best for which type of photo? Is it just trial an error or are there ratings which you can adjust to depending upon the conditions?
Not sure if this is a silly question, but theres so much to learn!

you go and do a good
you go and do a good photography course and learn the tricks...
for high depth of field you need to go high F-stop eg F8 or F16 greater, for blurred foreground and back ground, with a crisp center object, low F-stop, under F5, F2 is best.
For speed yu want high shutter speeds and for low lights you go slow...not much to it.
Also good old fashion light meter with ASA ratings on it, helps you judge the conditions. Remember you can play with the ASA rating of the picture ( ie it was old fashion film, the higher the ASA, the faster the film takes in light, but more grain in the picture.)
if you lost, lol...not my fault...:-)
I often shoot about 5 or six frames of something I like, some at lower speeds and F-stops and some at higher etc..
