1909 Seneca 8 5x7, Seneca Triple Convertible Lens (at 8"), New Guy collodion (1.5 weeks old), Copper Sulfate developer, alumitype
f/32, 6 seconds
After 2 test plates and still getting ridiculous fog, I figured the copper developer is just too strong so I dumped it and made new stuff from some B&S concentrate I brought with me. Unfortunately that didn't help either...

Since I bought the 400-800mm I've been concerned it's a bit 'soft', with some odd out of focus images including ones with a strange 'glow'. This wasn't helped by a long thread on Reddit I came across where others were saying the same thing. In a conversation with someone close just after I'd bought the lens, they joked that it wasn't legit unless they could see the rings on Saturn. So I cunningly combined the two things.
The left is Saturn and while you can't see individual rings, you can see 'the ring' so to speak. On the right is Jupiter and its four largest moons. Am sure the clarity was aided by the cold clear winter skies over Xmas.
These have convinced me it's not the lens, it's the user, something I've also shared back to that thread on Reddit.
Both taken mounted on a tripod, with OSS switched off, and manually focussed.

Yes—2025 is shaping up to be the year flying car hybrids begin to leave the realm of sci-fi and enter early real-world deployment, though public test drives are still limited. Several companies are actively developing and showcasing roadable aircraft and eVTOL hybrids that blend highway driving with aerial mobility.
Hybrid Flying Vehicles in 2025
•XPENG AeroHT’s “Land Aircraft Carrier” -- This futuristic six-wheeled van houses a two-seater quadcopter that deploys from the rear. It’s designed for both highway driving and short-range urban flights. XPENG has begun building “flying camps” with takeoff platforms in China, and over 3,000 units have been preordered at around $275,000.
•Alef Aeronautics Model A -- A fully electric flying car certified for road and air use. It’s designed to drive like a regular car and take off vertically. Alef has received over 2,800 preorders, and the vehicle is expected to be available in limited release soon.
•Joby Aviation S4 -- While not a hybrid car, Joby’s eVTOL aircraft is piloted and undergoing test flights in major cities. It’s part of the broader urban air mobility push, with plans for flying taxi services.
•Urban Aeronautics CityHawk -- A hydrogen-powered VTOL vehicle aimed at medical transport and urban commuting. It’s still in testing but represents a different approach to hybrid aerial mobility.
Can You Test Drive One?
•Not quite yet for the general public. Most models are still in prototype or early production phases, with regulatory hurdles and infrastructure (like vertiports) being built out.
•XPENG and Alef are closest to offering consumer-ready vehicles, but current access is limited to investors, early adopters, or demonstration events.
The Road Ahead
Urban air mobility is transitioning from concept to reality, with cities planning for airborne corridors and miniature airports. The dream of a highway-to-sky hybrid vehicle is no longer far-fetched—it’s a matter of infrastructure, certification, and affordability.

test dress, was meant for blythe, but the neck part didn't work out ^^; even now the neck part is a bit not what I'd like :P but looks cute on Vivi! :3
Some interesting test runs being conducted. Caught 1/7 of the Metro Adelaide tram fleet (of 21) in one shot. Newby 209, Bombardier 113 near the 1/4 Grand Union, and another Citadis just entering the same intersection from North Terrace (west). © Henk Graalman
can you BELIEVE the twins will be THREE this weekend????
that means my D3 is even older so I have been testing a new camera.
follow along on the blog!
Recently more of these TEST bricks have been found on a secondhand market in Denmark.
I was fortunate enough to be able to win some, though I did pay a big price.
Check out how equal the metallic stripes are on each brick…
These were found together with a 1x4 brick, a 1x2 brick, a 1x4 tile, 2x4 plate and a 2x2 45 degrees slope.
There might also be a 2x6 or 2x8 brick out there, though I have not seen it.
Colors look to be mostly metallic colors, though some are more normal, like the red and milky white.
Just got my test roll back from my new Pentax 645N and they're all beautiful. Another medium format keeper.

Taken with my new Ricoh GRD III. I went out at lunchtime today and had a walk around sheffield. I was looking to test the performance of this amazing little camera.
All these shots are straight out of the camera.
Next year I have been asked to take photographs at a friends wedding which is a huge responsibility.I have aqquired a used Nikkor 80-200mm f/2.8 pro lense.I took a test shot below at f/2.8 1/640 on my full frame D700 to check the sharpness of the image.Most consumer lenses tend to fall down when shot at full aperture.No post editing I could read the Perrys beneath the letter 3 when enlarged.Really pleased with the sharpness & bokeh of the result I think the portraits will be great.
Nowadays HGV testing stations don't really cater for 4x2 tractor units designed for 38 tonnes or less. Their "test" trailers used to provide a laden test scenario on the brake rollers can be either too heavy and or not suitable for coupling to older tractor units.
K4CSG was submitted for testing in East Anglia and Kevin Dennis kindly provided this trailer and a suitable load for the purpose.

First test roll in my new mystery camera the German made Hexi. I used iso 160 and decided to do multiple exposures (for some reason..) I'm quite surprised at how sharp and contrasty the images are...
more of a test shot to get a feel for an upcoming night shot. ;)

Testing the Fuji 50-140mm f/2.8. Someone commented that this lens has a case of confused identity bec. it thinks it is a prime lens. I believe that person may very well be right. :P I am gonna try this lens in a sports setting soon to see how it fares.
Dragged a car battery and an inverter out onto the back field to test out a 10m length of mains-powered ropelights. A bit daft really. I'm sure the lights themselves would manage with 12V is there was enough current getting through. 2A per metre apparently. I need to get it attached to a smaller battery if it's going to be mobile.
The 10m is doubledup twice here, so it's 4strands, each 2m in length, with the excess hidden, as swinging 10m straight out proved to keep hitting bushes, and was a bit iffy. Probably a 2-person job really. But it's got potential as a largescale LP tool as it's bright. This is a 2.5s exposure, so they're moving quite quickly, at a greater distance, moved slower, they should still show up OK.
