Okay.. I've been shooting prints for over 1 year now. Almost 100% of it being Kodak Gold 100 or 200. Up to this past Christmas I would use a flatbed to scan 4x6 prints but I received a negative scanner, so now I'm scanning the negatives. But heres the problem I recently encountered on some of my negatives that I never had a problem with on print scans:

(not the best photo, just a good example of the streaks)

It seems most apparent with darker pics- but on some it doesn't show up at all  Confused.. I did some searching on the forums and it seems as if this could be caused by poor developing? Is there any way to clean the negative to rid this problem? Or am I stuck with many "ruined" images that only have hope with the dodge/burn tools in PS?

I have been looking into slide films lately and shot off a roll of K64. No streaks at all, from the same scanner. Now I see why Mr. Pries loves K64 so much (consistant)  Big grin.. Currently I have a roll of Velvia 50 in my camera- gonna try and limit it to ramp/low-action shots though since my lense isn't very fast! I'm just trying to experiment with some of the "good stuff" as I'm ready for a switch!

thanks for any help,

Serge, thats most likely something on your negative - take a look through a 10x loupe, if there is any garbage on the negative, it will show right up!

I recommend you shoot slides, they come out much nicer when scanned.

Also, I would recommend developing your film at a professional place, where you can actually trust the people.

Thanks for the reply. However, I was referring to the dark and light colored vertical streaks on the photo, not the vertical white dust.  Smile

A big streak runs right through the cockpit and small Big Sky titles in the photo..

The negative hasn't been bent or folded has it?

Hi Lee,

Nope, nothing like that. But the main way on my scanner to scan negatives is to run them through the batch feed system- the negative has to be flexed into a 90* right angle to go around the corner when scanned.

The negative feed is the deal on the right..

Do you think that might be a problem? As an experiment later on, I will scan all four photos on a neg strip through the batch scan, then I will cut the photos up into single frames and place them in the adapter in the front (mainly used for slides). Then I will compare and see if the photos are any different..

I hope I'm onto something, I'll be happy if its just my scanner (they can be replaced, most of the GA photos I have cannot  Sad)
