Thank you all for the suggestions I will have to try something to soften the 
flash.

LED lights can have a weird colour temperature and spectrum (white balance). 
If your camera can take a pre-set white balance under whatever LED lighting 
conditions, so much the better.

Off-camera flash, or steady lights (you can get LED lights fairly
cheaply on ebay or aliexpress but I have not tried them), or put
something over the flash to direct the light upwards.

Since you still have good detail there; you could check in darktable
(assuming you're on Linux) or rawtherapee and see if any of the detail
can be recovered, but I doubt it.

An LED macro ring light is another possibility. But best is if the
light comes from the side, so it doesn't bounce off and hit the camera
lens. See if you can go without flash at all.

Hey David,

The photo didn't make it through to the list, alas - posting the URL
rather than a formatted link should bring it through.

Just as a guess it sounds like you will need to "paint over" the
unwanted reflestions in the images, replacing them with realistic
textures and contours that fit into the surrounding image smoothly.

Depending on the situation, resynthesizer tools like Heal Selection
might be exactly what you want:  That particular filter samples the
image around the selection, and uses the color, texture etc. of those
pixels to smoothly fill the selection.  The Heal tool - a clone tool
that does a similar trick to blend the cloned-in pixels with the
existing ones - sometimes also comes in handy for removing smaller
"visual clutter" from an image.

These tools are available in the gimp-plugin-registry package on .deb
family (and I would bet .rpm) repositories.  I'm not sure if it's in the
Windows binary distribution or has to be downloaded separately.

You might get different and/or better advice when we have seen your
example image.

David,

If you're considering an umbrella for your flash, a simple search for 
"flash umbrella" will turn up lots of sources and tips.


Hope this helps.

Rick

The specular reflections cn be spread out so the details won't get lost 
by carrying a big silver umbrella the flash is aimed into. With the 
umbrellas silver surface, the power of the flash will be more widely 
dispersed, and while you'll still see the gloss, it will be distributed 
over a much wider area, and not near as bright as it is using the bare 
flash, which is nearly a point source. Check in Popular Phography 
magazine for dealers who still actually service the photo arts.  They 
used to come in a wide variety of sizes, and one that opens to 3 or more 
foot diameter, with a tripod to position it and a pad to mount the flash 
to, should help give you a lot better image quality.

Too many times the image is overexposed and details lost when doing 
digital photography.

I used to do portraits with high contrast copy film developed in d-23 to 
lower the contrast, and was pleasantly amazed at the difference a pair 
of big umbrellas made, negatives miss-exposed by half a stop or more 
were still usable in the darkroom when making the prints. HCC film will 
display every failure of your cameras lens in glorious black and white, 
but if you get it right, you can count every hair and skin pore in a 
print you shot from 6 or 7 feet away. Doing my own color printing in the 
darkroom with chemical processes, I found it quite easy to make color 
prints that beat digital for sharpness by at least 50 times unless you 
spend several thousand just for the camera body.  Todays $200 digital 
camera is the box brownie of the 1940's, with a slightly better lens.

Sadly, that technology, and the precision art form it could do, has been 
destroyed by the nearly instant digital photography print.  Supplies for 
that method of taking a picture have dried up, and I read someplace, 
several years ago where Kodak had shut down the last film production 
line.  Fuji might still be making some but I haven't checked in 2 
decades. 

Mmmm, I guess I am showing my age aren't I?

Cheers, Gene Heskett

Unfortunately the image didn't make it through the forum/mailing-list.

Are you using a flash? If so, try moving it off-camera, e.g. wth an
extension cable.

If the image is over-exposed and details are lost, an image editor
can't really restore them. But try setting your camera to save in raw
format. If you're on Linux, use darktable, and/or RawTherapee, to open
the raw image file and see if the details can be recovered.

If it's reflections not from the insect's carapace but from glass, a
polarizing filter on the lens may help. They are available for a wide
variety of cameras. Or, use a piece of black card to shade the glass
from the light.

Hey David,

The photo didn't make it through to the list, alas - posting the URL
rather than a formatted link should bring it through.

Just as a guess it sounds like you will need to "paint over" the
unwanted reflestions in the images, replacing them with realistic
textures and contours that fit into the surrounding image smoothly.

Depending on the situation, resynthesizer tools like Heal Selection
might be exactly what you want:  That particular filter samples the
image around the selection, and uses the color, texture etc. of those
pixels to smoothly fill the selection.  The Heal tool - a clone tool
that does a similar trick to blend the cloned-in pixels with the
existing ones - sometimes also comes in handy for removing smaller
"visual clutter" from an image.

These tools are available in the gimp-plugin-registry package on .deb
family (and I would bet .rpm) repositories.  I'm not sure if it's in the
Windows binary distribution or has to be downloaded separately.

You might get different and/or better advice when we have seen your
example image.
