I have been fascinated by photography ever since I was a child. These days I am seldom more than a few metres from a camera. My photographic interests sprawl from artificial intelligence through to vintage zoom lenses. Unsurprisingly, there’s also quite a lot of Linux in the middle. :-) More…
A couple of months back, a question was raised with regard to how to prevent cable connectors falling out of cameras during tethered shoots. Well my tethered shoots are almost always tethered wirelessly these days. However I do sometimes need to attach a power lead. As my wife reminded me, when we’ve done shoots with…
The subject of monopods was raised recently in a photographic forum to which I belong. As it happens, I was already flirting with the idea of using a walking stick as a monopod, to avoid the need to carry two sticks. I’m a lazy so-and-so at the best of times. I also have a habit…
Photographer pal changed the batteries in his dead YN565EX II speedlight flash gun. Unfortunately when he tried to witch it on, it didn’t work. He tried several sets of batteries. No luck. For those not familiar with the device, the Yongnuo YN565EX II is a relatively affordable battery-powered Chinese flash speedlight for both professional and…
Several people have contacted me privately and asked for information regarding how I actually mounted my 120-year-old Bausch & Lomb + Beck lens on my µ4/3 camera. I hope in this article to shed a little light on how one can make such an old lens and seemingly-incompatible lens actually stay on a modern mirrorless…
Regular readers may know that my 2023 Christmas project was to make this 120 year old Bausch & Lomb + Beck lens fit on my µ4/3 cameras and actually capture some pictures with it. Unfortunately, at the time, the weather was too wet to take the thing outdoors. Fortunately by early January the weather became…
Over Christmas I set myself a little task of trying to make a 120-year- old Bausch & Lomb + Beck lens fit on a fairly modern camera. The lens was given to me in the late 1980’s by one of my very first models. It was a nice thought but to be honest, I came…
I always rather fancied a decent 500mm catadioptric lens. I bought a cheap Korean one off eBay a few years back and frankly it was not very good. But the old Tamron 500mm mirror lens has quite a good reputation. And as luck would have it, one turned up cheap on eBay a few weeks…
My experience of street photography is to make oneself looks as insignificant and unprofessional as possible – which comes rather too naturally to me, TBH! 🙂 Kit should be small, light and ideally somewhat battered looking – a “distressed” look that most of my kit usually acquires after a few weeks’ service. No expensive-looking kit…
Bought a bundle of multifunction USB rechargeable LED lights from a supplier AliExpress. I actually a bought batch of both types shown below because I like them so much. I paid a bit over a fiver each for them. Quite amazing for their size, weight and cost. Tough, water-resistant and rechargeable via USB C, c/w…
I don’t quite know how I managed it but my personal/business dataset has now grown to around 17 Terrabytes. Most of it is spread across multiple smaller disks. This is becoming increasingly difficult to manage. In fact, we are decommissioning our 4TB drives. This is partly because they are well beyond recommended end of life,…
Nurses’ noisy but good-humoured protest outside Southampton General Hospital today as first ever major NHS nurses strikes in British history take place. Something about this touched me. Perhaps it was the sadness that these hard-working decent people have to do this. Or perhaps it was the gentle considerate way they did it. Every bus and…
For my little IT business, the possibility of power cuts is very bad news indeed. So we invested in one of these things – a “UA1101l” power storage unit. On paper, it stores about 3.6 MJ (megajoules) or 1 kWh (kilowatt hour) in EV (electric vehicle) grade LiFePO4 (lithium iron phosphate) batteries. My tests suggest…
We’re busy replacing a customer’s ageing Sonos distributed sound system with a Linux Media Server (c/w SAMBA for remaining Sonos kit) c/w these tiny Linux-powered SBCs (single board commuters) as replacements. Granted, this is merely a prototype. This unit us based upon a Raspberry pi 4B c/w 8GiB RAM, a capacitative touchscreen and an external…
I just bought a Geiger counter from a seller on AliExpress. Well it’s actually a Geiger counter and EMF (electromagnetic field) meter, all combined into a single device. I have no idea who actually makes these things. There is no branding other than a model number “BR-9C”. Though I did discover that the enclosures used…
A lot of buzz on the interwebs about Samsung mobile phone batteries. Whilst Samsung devices do seem particularly problematic, it can be an issue with lithium polymer batteries generally – especially the super skinny type. They really don’t like getting hot. I confess I documented this repair rather badly but I did remember to capture…
Like quite a few photographers, I have been flirting with AI (artificial intelligence) digital imaging. Regular readers may even have spotted my Synthetic Stupidity gallery dedicated to the fact that at the moment, publicly available AI graphics tools really aren’t particularly good – even though they are quite good fun to play with. In fact…
I have just been listening to Mr Trump and his supporters explaining the situation concerning all those crates of secret documents that the FBI found in is house at Mar-a Largo. Apparently, the documents were all planted at Mar-a-Lardo by the FBI, they were not at all important, and Mr Trump had declassified them all…
JPEG (Joint Photographic Experts Group) format for images has served us well for nearly three decades. But is is essentially a 1990’s format. Today we have better ways of compressing images. The most popular currently is Google’s WEBP (Web Picture) Format. Many modern websites use WebP as its default format for uploaded images that it…
I’m ashamed to admit that I managed to drop my camera c/w my favourite 14mm-150mm Tamron super-zoom lens yesterday. I failed to secure the camera correctly to the tripod and it fell crashing to the ground, lens-first. Fortunately the camera, a tiny µ4/3 Lumix DMC-GX7, seemed unharmed. Even more fortunate, I generally I use those…
A few folks have asked me what I use to keep our various networking and internet connectivity kit neat and tidy, yet reasonably service friendly. Well, I have to admit that it was rather a muddle for a many years. That was until I decided to make a simple multistorey stainless steel router rack. Moreover,…
Some readers may remember that during lockdown, I wrote an article concerning the large stag beetle grubs I discovered round the back of my shed? Well, it seems the stag beetle grubs have grown up now – well some of them have anyway. I discovered quite a few adults in our garden lately. Yesterday, I…
These days almost all digital cameras offer excellent light metering, The old fashioned “light meter” has become a “thing of the past” to a large extent. Nevertheless they do still have their uses. For those still wishing to flirt with light meters but who don’t want to fork-out to the £100 or so that a…
It was a lazy Bank Holiday Monday morning and we had just crawled out of bed, when we heard a bit of a splash outside. We opened the curtains and noticed the water in the pond was moving, But we didn’t know why. Fortunately Zoneminder captured the incident from one of our security cameras. So…
This is a remake of an earlier video, driving through the Hungarian M6 / E73 Tunnels, with the soundtrack written by Rob Weller.
How do I calculate the kWH on my studio flash heads? Do I use 300 watts of electricity each time I fire them?
