I should have known that there would be some good answers from you clowns.
It is the dark ring around the duck that is bugging me.
is the smear there on the the original?
It's probably most helpful to shoot something like the clear sky, with the lens far out of focus at a high aperture (focus near) and shoot at various exposure compensations (really light/ really dark) and see if the smear is there. When looking at the files, do a really extreme contrast tonal adjustment (make the darks black and the lights white), to really show up anything dirt on the sensor. Be prepared to see a huge amount of dust.
I have a similar dark spot from my sensor, but several cleanings have not gotten rid of it. Mine is at the edge and it's usually not noticeable, gets cropped out anyway, or is easily cloned out.
Oh I know what it is... he is making excuses to upgrade to a 50d or a 5d mk II.. are you now?
;-);-)
I am trying to build a case so I can show my wife. "See honey, I can't work with this. This is unacceptable!" Ha
Her reply would be "See what, who's gonna notice?"
So no upgrade!
I managed to get that big fluff off, but man , I found more shit on that sensor. Any recommendations on a DIY cleaning kit. I have tried the blower but its not working. I think I need to swipe it. Also how do I get my viewfinder spotless. The mirror is clean, its the other screen on the underside of the mount opening.(opposite of the mirror)(not the sensor) Don't know the technical name for it.
looks like a stain (water, grease from shutter)on the sensor, you may be brave enough to do a wet swab clean on your camera. I have become real pro at this now and have a delkin sensor scope (i do not use their swabs as they are total crap)I use VisableDust V swab they are great. The sensor scope is fantastic device that let's you view the sensor close up to see the crap that is causing the trouble so you can pin-point your cleaning target. Good luck with it
I've used the Copperhill product with great success. I've never had any problems on either my 20D or 5D.
Glad someone posted that. Cleaning supplies need not be expensive. A little Eclipse fluid goes a long way, and Pec Pads make great swipes when wrapped on a home made holder. Required cleaning frequency will vary greatly depending on:
- The camera model (the 5D shows dust particularly badly)
- Your sensitivity to small particles (the closer you look, the more you see, and if that bugs you...)
- How often you shoot with small aperture (dust is far more visible at f/16 than f/2.8)
- How much you shoot, and in what conditions, and how often you change lenses
Typically, a few times a year is sufficient; come folks clean much more, some less.
