I agree, Mark. Both males.

Re: Communal Dragonfly, Butterfly and Insect photo thread

Hoverfly Xanthogramma pedissequum

I was walking through our conservatory when this flew past me and settled on the leaf of a Bougainvillea, where it remained for many minutes. There were leaves obstructing the view from one side and the house wall, leaving no room to angle the camera, on the other (my left).The fly was very amenable to being directed to some extent by my finger tip, even making to climb onto it. However, I was unable to get anything like a head-on shot.

Olympus EM-1 (aperture priority), Olympus 4/3 x2 TC, Olympus 4/3 50mm f2 macro, 1/13, 1/25 & 1/25 sec at f10, hand-held.

The stereo is crosseye.

Harold

Unhappy Re: Communal Dragonfly, Butterfly and Insect photo thread

Nice photos Harold, but still cannot get the hang of the 3D image.

Used to be able to with Aerial photos as a surveyor......

Thanks, Mark.

Sometimes the stereos are a bit uncomfortable and not easy to view. This pair are spot on. Relaxing your focus to slightly distant is important.

Have you tried placing your screen on the floor, facing vertically upwards, and standing over it? You never know!

Harold

Re: Communal Dragonfly, Butterfly and Insect photo thread

Female Long-winged Conehead Crickets

I recently posted images of the males. More recently, I have found two females to be present at the same time, even on the same leaf (penultimate image). Several of these shots show the cricket eating brownish plant material, perhaps some kind of bud scales or similar material.

I have shown the images in the original orientation of the cricket to the vertical, thus keeping the shadows natural. In the second one I had needed to turn up the edge of the leaf to access the underside.

These crickets are quite small, about the size of a Meadow Grasshopper. The maximum magnification used was 1:1 (FOV 17.5mm wide).

Olympus EM-1 (aperture priority), Olympus 4/3 x2 TC, Olympus 4/3 50mm f2 macro, f11 (f9 for last), hand-held.

Harold

Re: Communal Dragonfly, Butterfly and Insect photo thread

Having just taken some photos of bright yellow/red butterflies in a tropical plant house, I'm rather confused! When I was taking the shots I was surprised to see that the bright yellow bands seemed white in my Pen-F's viewfinder. Initially I put this down to a colour balance issue in the viewfinder, but on looking at the JPGs on the rear screen they still looked white and red! I haven't downloaded them yet and checked the RAW images, or tried playing with the colour balance (the camera was on autoWB and the lighting seemed to be balanced to the outside daylight). But could it be one of those colours that don't get reproduced accurately in camera? I also feel that bluebells never look the same on screen as they do in real life!

When you open the RAW files in processing software chose the "open as" for the correct WB I would never trust AutoWB as it has to be a compromise. Don't save any changes back to the RAW files.

Well I'm still baffled!

I've opened the RAW files in Olympus Viewer, and the bright yellow patches are white. I've tried altering the colour balance, and adjusting the exposure and contrast, but cannot get the image to reflect what I saw

The foliage all looks OK, but either the yellow was so bright that it was way over-exposed or it was an optical illusion and impossible to photograph!

Chris,

Your butterfly is Heliconius charithonia. All of the images I can find have either white or very pale yellow markings. Could it be that the brighter colours were on another species of Heliconius, or another geographical variant, in the same location?

Re: Communal Dragonfly, Butterfly and Insect photo thread

Digital colour reproduction is a 40 gallon drum of worms!

The late Bruce Fraser was an expert on the subject and a dip into his books will show how horribly complicated it is. IIRC yellow can be difficult to reproduce accurately on the screen (made from green and red dots). Some colours cannot be displayed accurately on a RGB monitor, but can on a CMY printer and vise versa. It all seems to be a compromise and a miracle that we get anything resembling reality on the screen or paper! And don't even look at metamerism or you'll give up on colour entirely and go B&W!

Jim

The two butterflies I posted were in the Tropical Butterfly House at the National Botanical Centre of Wales. I didn't see any identification charts there, so cannot tell you whether or not they were a variant of the one you linked to.

The Butterfly with the red bar also had brilliant yellow stripes rather than white in real life, while the zebra-striped one was really yellower -- more like the Heliconius charithonia on passion-vine in Mexico City, Mexico in your link.

I suspect Jim has solved my question and it's all down to digital reproduction. Now was Velvia any better I wonder??

Yellow was always a problem with reversal film. The I found the one which was good: Konica Minolta Chrome Centuria.
