How to Make Washed Out Pencil Clearer?
February 25, 2016 6:53 PM   Subscribe

So whoever bashed up my bumper kindly left their number. Problem is, the rain and snow washed out some of the digits. (The search space is >100, which is more people than I really want to cold call.) Any way to bring out whatever smidges of graphite are left? Without, you know, university level signal processing software?

Could you post an image of the number?

Scan it and toss it into Paint.net? Play with the contrast and darkness levels?

Can you check out the underside of the paper and see if there's an impression you could examine?

If you don't have a good photo editing program and Paint doesn't do the job, post a high res image (scanned if possible) and I'll see if Photoshopping it can help.

Post an image here. We did this once several years ago with a license plate number.

Yes, lots of skilled image manipulators around here. Just crop out and post the digits you're unsure of if you want to avoid posting this person's whole phone number online.

Also most phone apps have contrast and brightness levels in either their native photo program or free apps.

N-thing post a de-identifiable hu res scan of what you have! There's a whole hive of us crackshot 'shoppers champing at the bit to have chomp of it! Heck, I've fired up my Photoshop in eager anticipation of it already!!

Response by poster: Thanks, guys! Here are five scans of the vague missive. The last one is the highest resolution. I also lowered contrast to preserve information. I preserved the clear digits for comparison.

It almost looks deliberately badly written at the end, though I think the last digit is clearly 4 (that tail doesn't look like part of the number to me), reducing your number of possibilities to 10.

I'm with Pope Guilty. I think it's intentionally badly written; also, pencil shouldn't really be washed out by water.

I ran the image through some photoshop sharpening, contrast adjustment, looking at different channels etc, and didn't seem to get any more detail out of that second or third digit. It seems almost like they didn't even write four digits though?

02?4

Looks like it's a cell phone number.

I feel as though it looks as if the numbers have been deliberately obscured, it seems like they are crammed into a small space compared to the rest of the writing. And just saying "Call me" without a name doesn't bode well for the person genuinely wanting to be reached. But, maybe they were drunk and not managing writing very well.

It looks like felt tip marker to me, not pencil -- what is it?

Pope Guilty, my intention is not to quibble with your answer but it seems like you might have left some info out that the OP could use. if there are 10 possibilities that implies that you could make out 3 of the last 4 digits. To me it looks like there is just a zero at the beginning of that group, and I suspect many other people are also only able to make out that number. If you can make out an additional digit between the 0 and that last one I'm guessing the OP would find that helpful.

I'm reading the first two of the last grouping as 07. I of course may well be wrong.

The writer's 9's and 4's are straight on the bottom, where the last digit has a curve. I say it's a partially erased 8.

I'm not convinced the tail is meant to be part of the 4, is the thing.

It doesn't look washed out to me at all. I'd say it's a case of "My girlfriend and the 3 people who saw me hit the car think I'm writing my number, but I'm actually going to just scribble a bit after this 0."

To me it looks like letters. 514-691-OJAY. The O could be a letter or a number.
