I have heard of a program that will fade textures. I have trouble with the heavy hexagon textures. I am hoping that I won’t have to buy a special scanner to remove this effect, they are very expensive. Any ideas?

can you post a sample? where are the images coming from? are you talking about moire patterns that you get when scanning from a magazine?

I’m guessing he’s talking about the honeycomb texture on the surface of some old photographic printing paper.

This is always a toughie, and when the subject has come up before, I don’t recall anyone coming up with a really foolproof solution, outside of reshooting the image with strong, diffused lighting.

You might try just making a copy negative or just take a picture with a digital camera.

I wonder if it would be possible to modify a cheap scanner to have a constant light source and disable the carriage light or if it would do any good if you could.

Phosphor,

I remember that topic.

1)someone mentioning coating the scanner glass with a thin coat of some kind of syrup (didn’t sound like something I would want to do).

2)using cardboard spacers to keep the image just off the glass because sometimes the pattern is cause by contact with the glass.

3)Scan, rotate 90°, Scan Again and merge the two in an effort to get the best parts of the two scans.

Phosphor;
You have the right effect in mind. Do you think I should still try to post a sample? I seen the program I was reffering to, work. It can really do a good job. You just select the size and shape and power. I don’t remember if there was a choice for color.

filter-Gaussian blur (value 1 or less)

Absolutely.

I can’t seem to figure out how to post a picture.

Phos,

I have mentioned the only foolproof remedy for this several times (been using it for over 30 years), but am usually howled down or totally ignored because:

1) it is a photographic solution, not a software one,

2) it requires expenditure (very moderate),

3) it requires a bit of research for those without photographic knowledge.

Contra-polarizing involves polarizing gels over copy lights set at 45° to a copy board, with a polarizer on the copy lens rotated in opposite orientation to the gels over the lights.

This will completely remove all spurious reflections and will give full colour saturation (as opposed to diffuse lighting, which just spreads reflections and desaturates colour). Unless the hex pattern is caused by an absence of image/emulsion in the valleys (as happened sometimes with cheap paper with poor or very thin coating – a magnifier will soon reveal if this is the case), copying the original this way will COMPLETELY remove the hex pattern. Full stop. No need for glycerine, Vaseline, chewing gum & baling wire rigs or guesswork.

The process is fully explained in Kodak publication M-1 "Copying and Duplicating in Black-and-White and Color". (Out of print, but Amazon had a few copies last time I checked a month or so ago.)

As it actually alters the physical properties of the light, it cannot be duplicated through a software fix, and it DOES work extremely well.

Fred.

nvslater,

Go to <http://imageshack.us>. They only accept png, jpg, gif, etc., and have a 1 meg limit, but it’s free. Or you use your own website or a free website, and then tell us the link.

Fred,

Your method may be absolutely perfect IF you are interpreting his discription accurately. The reason I’m suggesting a post is to remove all doubt.

Peace,
Tony

Tony,

I was responding to Phos’ post #2 as much as anything.

Anyhow, post #2 + post # 4 = betcha I’m right. 🙂

Fred.

I think MY reply was the best one especially after seeing the picture with the posted link.
I suggested doing a Gaussian blur with a value of 1 or less and then sharpening just a little bit.
this method worked for me in the past
