Re: Wax Myrtle

Very interesting subject! I also really like the contrast & colors in the images, reminds me of shooting on Fuji Velvia. It also does not have the usual bright red or purple color of fruits that evolved to appeal to typical frugivores. Do you know of other North American fruits like these, with waxy...

Re: need advice about shooting coins

like pure white or black background or something closer to the tonal range of the coin? Or the edges - lighting like the coin or a lot darker? Contrast - do I want shadows close to black or just slightly darker and vice versa - bright highlights or just slightly lighter? Or avoid deep shadows and b...

Re: Fujifilm X-H2S, any thoughts/users?

- I don't shoot tethered (maybe I should) I have some pretty nice scientific cameras which I use when I am required to, or when I am bothered. Therefore, there is an argument for me to get a PC, perhaps one of the pocket ones just to run my microscopy stuff. I want to stay far away from frame grabb...

Re: Fujifilm X-H2S, any thoughts/users?

I'll throw an oddball into the mix: Basler Ace 2 ( model a2A5328-22g5cBAS ) Kind of / sort of checks every box, adds a few more, and costs about the same. - 1.2" Sony Pregius S IMX540 sensor with 24.4 Megapixels. While not a aps-c format, you do gain the option for significantly cheaper c-mount lens...

Re: The Mysterious El-Zoom Nikkor

I was finally able to publish a first version of the article on Noritsu lenses here: https://deltalenses.com/the-makers-noritsu/ Fantastic work! The different types of photos taken with each lens really adds something fascinating to the whole article! I'd be curious to know just how many (roughly) ...

Re: BH-2 SPlan for SPlanApo - Exchange Rate

+1 for what houstontx said. I think it ultimately depends on the condition, but you can pretty much guarantee 2x the price. For reference: I wouldn't want to spend over $100 on a average condition 20x splan with an unknown history - on the flip side the the 20x APO's sell for $295-300 on eBay all th...

Re: FS - High Resolution Test Targets

Forgot I still had one more to get rid of. Someone get this to a new home! Where else are you going to find a sub micron test target for less than a grand?

Price update: $150 Shipped within the lower 48 states.

Will entertain international shipments with the buyer paying shipping fees.

Diamonds

Feels like a long time since I posted anything. So here are a few pictures I took this past week - playing around with getting an efficient coaxial illumination setup working. I believe this is an early era lab grown diamond although I cannot say for certain at the moment. Have to find the box I put...

Re: Iridescent Butterfly Wing Scale @ 100x

Very nice image! I personally like the deep contrast of this one. For your issue: you can try a pseudo HDR by lifting the shadows on one copy of images pre stack, then stack both sets of images, and finally HDR merge them. Flocking or painting the front of your objective housing may help. I have had...

Re: RFID chip from "Alien 9662" label

NXP is a Dutch semiconductor manufacturer that make a pretty well known RFID chip by the name - UCODE HSL ( H igh frequency S mart L abel.) Most IC's will list the version number, either directly in the product code, or separately with the date. So the "B1" that follows the "V" in number on the IC i...

Re: New to macro photography....

Welcome to the forum! Your images are pretty dang good for an absolute beginner. Some of the halos, or fringing, I believe you are talking about are pretty common in stacks of insects / or deep stacks with a large DOF. Zerene seems to do a much better job compared to Helicon in managing those, as we...

Re: Guess the Crystal

Having finally registered the scale and jaw-dropping number of shots, I doubt ice would remain looking the same over such a long time. But I'll leave the answer. I am very much looking forward to details on the "how" of it all though. Hope you can reveal that - in due course. Thanks. Silver halide ...
