strange lines CPL or Lens??

[tristan]

Hi, I just got back from a trip out west and got some great shots 2 things happen to my great shots.... I got bad dust spots on the dark blue sky and there is strange lines running through my photos not all but some. I am sure you would like to see examples but I dont have any untill later tonight. Is there anything I can do?

We'll tell you when we see the examples.

Could be on/in the lens, on the cpl, on the sensor, anywhere. I'm assuming you were using a small aperture (smaller than f/8 or so). This will generally show any dust and grime on those sections. The "strange lines" may be hairs or fibers.

[tristan]

No these were landscape shots so small apeture was used.

Its a bad quality jpeg for one, so it is a bit hard to tell dust from artifacts but I do see a few spots, I'd suggest a rocket-blower or something similar, when you squeeze it fires compressed air, blowing away any dust on the sensor.

I don't see any strange lines though. (I hope you aren't referring to the lines in the hills, I'd hope people realise those are the mountains textures themselves.)

The lines could be any of several different issues.
I too can't see lines in that posted pic ...

Do you mean the mostly horizontal lines in the hills?

If so, those are not artifacts. They are the different layers of the rock and dirt that form the hill.

Enjoy! Lon

I don't see any lines. I thought you were talking about some sort of horizontal banding. I just think the image saved is a bit too low quality.

[tristan]

No the horizontal lines I was speaking of showed up in the mountain pictures most of all. I could only see it on certain montors aslo could have been the monitor I guess. But the dirt specks are visable in a lot of my pictures this one has a lot of them but I couldnt compress the file right for everyone to see the specs. I am pretty sure it was on the sensor because I moved the CPL around a bit in some shots and the dust didnt move one bit but you could tell I moved the Poloarizer though.

Were the lines black? Was it on CRT displays (regular monitors, not LCD panels)? Many displays based on Sony's Trinitron technology (including many Apple displays) will have one or two 1px wide horizontal band(s) that are hard to notice, but if you're looking critically at a picture, you'd see them. *shrug*

I don't see the lines either. The dust specs are easily rectified by cleaning your sensor or using the clone tool in Photoshop. If you have a small dust spec on your filter or front element of your lens you won't see this as it is normally focussed out when you are shooting a scene like you have given us here.

Grr.. I wish I could upload a pic that had the lines... When I seen the lines it wasnt on a lap top like I am using now it was a regular monitor. The specs were cleaned up with clone tool but man o man. What can I use to clean that sensor? and how did it get that dirty I try really hard to avoid dusty areas when changing lenses.

Could be interference patterns - show up at some scales only, when the patterns don't display quite right because of the scale of the pixels on the monitor doesn't match the lines / patterns in the pic - or something like that. Happens with hair and plaid shirts...

You will get dust on the sensor no matter what you do. Sorry it's a fact of life.
Do a search on sensor cleaning and you'll get masses of good info:)

Sensor cleaning is really not hard at all
