Grave matters

A friend here has come up with an interesting photographic challenge. He is part of a group who are restoring a long-disused churchyard as a wild nature garden. There are various gravestones and they would like to identify them, but the inscriptions are very worn and difficult to see. He was wondering if I could do any magic with camera/Photoshop to make them clearer.

I've had a few thoughts - the simplest being to take a straight photo and whack the contrast way up. Also to try lighting from the side to emphasise any relief, and maybe even to sidelight with a coloured gel on the flash, say yellow, and boost contrast in the complementary channel which in this case would be blue. Or use 2 flashes with complementary coloured gels from opposite sides.

Has anyone tried this sort of thing and could give me some tips? Or know of any good info sources on the Interweb? I'm due to make a first scouting visit tomorrow but I don't think there is any great urgency as this is a pretty long-term project.

Thanks in anticipation ... John

Yeah, it's not like they are going anywhere!

Seriously, this sounds a fascinating challenge and I can't think of anything to add to the promising ideas you already have. I will be interested to see how this project progresses.

Re: Grave matters

How about the old trick. In photoshop add a duplicate layer, then some Gaussian blur on the new layer. Change the blending mode to soft light and play about with the opacity.
This will contrast things up. Then merge visible and sharpen as usual.

Might work.

Re: Grave matters

Has he tried wax crayon rub? Put a clean sheet of newsprint or light paper over the writing and rub a crayon over it the writing should show up use crayon sideways and build up in layers. Ed

Re: Grave matters

Thanks Andy and Ed. I did wonder about wax rubbing, the weather forecast suggests that won't be a good option for a little while yet! I had forgotten about the duplicate layer/Gaussian blur trick, thanks Andy for the reminder.

Re: Grave matters

You can use a line generator (builders laser level) to build up a topographical map. It's quite a complex process, but with live view bulb it should be easier to get right.

The shallower the angle of the beam to the surface the greater the deviation of the line due to surface imperfections. It's a similar technique that is used to map railway tunnels, caves etc..

You would need to do this at night, which will likely put off a lot of people and may well attract the attention of the authorities.

You might like to contact the Norfolk Medieval Graffiti Survey for suggestions. Their site http://www.medieval-graffiti.co.uk/ is interesting in any event.

Re: Grave matters

I have had some success with photographing these inscriptions by Infra Red. It does not seem to make a vast amount of difference but it certainly makes them clearer. I am in fact lucky in that my EP1 plus an IR filter seems to work well without any camera mods,

Re: Grave matters

Thanks Graham, Andrew, Roger. Some off-the-wall stuff there!

Graham - doing stuff at night probably wouldn't be a problem. The area is currently locked and the woman leading the project is very enthusiastic . So the major problem would be commitment on the part of the photographer

Thanks Andrew for the website, I will take a look.

Roger, interesting thought. I don't have a hardcore IR filter but I have a fairly heavyweight one that was supposed to be for use with Ilford SFX (?) film. I'll tuck it in the bag tomorrow , but I guess if it's overcast or even raining there won't be a lot of IR around anyway.

More suggestions welcome .....

John

Re: Grave matters

Best of luck, make sure you get permission from the bodies concerned before you start rubbing them up.

If there's not a lot of natural sunlight, a powerful camera flash can help with IR photography - especially in this sort of situation.

Cheers,

Ralph.

Re: Grave matters

My advice here is in PP you need to separate the colour from the contrast by converting the Image to LAB mode and use a curves adjustment layer on the L channel to enhance the the detail. Another useful method is to split the image into the 10 channels available ie RGB, LAB and CMYK and with a combination of the Blend If command Curve adjustment layers and Layer Masks incredible results can be achieved, much more than just working within the RGB mode only. It might sound scary but worth the effort in the end.

Tom

Thanks Ralph, I'll be taking a couple of old Oly T32s which are reasonably beefy, I wondered if there would be a useful amount of IR from them.

And thanks Tom for the channels & blending suggestions. I had been thinking along those lines but not got nearly as far.

Looks like I will have plenty to play witxxxxxxxx think about tomorrow!

John
