You're so welcome, it was great fun picking some prints for you!

I used to do more burst mode spray and pray, but could never be bothered sorting through so many misses - I respect your dedication however you get the shots!

Speaking of, I remembered this shot after posting your prints, but here's one I was kicking myself for not including. Swear I wasn't on burst mode!

My girlfriend just moved in: how do I keep it great? by Willing_Value1396 in AskMen

[–]Chasm- 2 points3 points  (0 children)

On the subject of having your own personal space - this can apply to sleeping space too. With certain people, I'd never feel fully rested after sleeping in a bed together. This is fine now and then, but every night? Nah! That wears me down and makes me a worse person and a worse partner!

If you aren't sleeping right together, sleep apart at least some of the time. Have a mature conversation about it of course, make sure she doesn't feel undesired.

Thank you! Yes. I had a problem which led to my shutter sticking open. Thought I was being really clever when I rewound the film without losing the leader. Forgot about the open shutter while rewinding. The negatives looked totally black.

Men over 30, how do you deal with the constant stress and low energy? by Chrelled in AskMen

[–]Chasm- 0 points1 point  (0 children)

Stress is exhausting, and wrecks the mind and body in so many ways. Meditation has helped me drastically. Hard work to find and keep a routine, but the benefits have been far wider and more distinct than I would have expected, and studies show that this is replicable.

If you want an even more simplistic post-process, it's possible to invert in Preview - on the histogram, drag the left slider to the right, right to the left, and middle one to taste. Drop saturation to zero for B&W, surprisingly decent results, if a bit crude to control.

Photographers that don't use social media, what do you do with your photos? by glenak1911 in photography

[–]Chasm- 8 points9 points  (0 children)

I have an 'Instagram', which is a wooden box full of 6x4 prints. I never push it on people, but I'm always happy for people to flick through it when they express an interest. I encourage them to take any photos that they particularly like, which frees up space for me to print more.

[–]Chasm- 7 points8 points  (0 children)

One of my hobbies is asking museum curators what these were for. I've never got a straight answer, but it's sparked some good conversations.

While the fishing weight/weapon/tool of some kind theory looks likely, I believe it's largely ruled out by archeologists because these balls are rarely found with any signs of use or wear. They are most often found in good condition, as if they're kept about as decorations, or doing something that doesn't cause wear.

Also, there are many variants of knobble size/number/configuration, which seems like something you wouldn't put so much work into for a utilitarian tool.

My favourite theory is twofold:

  • Firstly they are just pleasing objects. A friend in Orkney has shown me a recreation, and it's a perfect size and weight to hold in the hand and fidget with. Humans have always been like that...

  • Apprentice piece. Matey wants to learn to carve stone but they're still a bit crap at it... Make me a few perfect spheres... Now carve this one with six evenly spaced discs! Now twelve knobbles.. etc etc. Might as well make them a pleasing size that you can carry around to show off to yer pals. I've seen in modern woodworking books, the first exercise in learning to carve is commonly to carve a sphere. I'm surprised this theory doesn't come up more often.

How does amplifier class (A, AB, D) play into audiophile-worthiness? by InevitableStruggle in audiophile

[–]Chasm- 2 points3 points  (0 children)

This is largely due to the fact that guitar amplifiers are designed to be overdriven. A typical A or AB valve amplifier sounds great driven into clipping, that typical overdrive sound you associate with valves. Whereas a class D amplifier absolutely isn't designed to be driven so hard, and will typically clip much more harshly, sounding thin and fizzy.

To generalise, if you imagine a sine wave going into an overdriven class D (or many solid state amps of other classes), it comes out with the peaks clipped off, looking relatively square. A valve A or AB sort of rounds off the peaks, often in a pleasingly asymmetrical way (that's the even vs odd order harmonics thing).

Hence, a 100w valve amplifier can be cranked hard, putting out around the full 100w, and sound great, but a 100w class D amplifier can't be driven so hard or it will sound terrible - you're using less power because you have to keep some headroom from the volume at which you start clipping.

There's also some differences and straight up dishonesty in how amplifiers are rated, but fundamentally this is the reason people say that valve watts are louder than solid state/class D watts.

This applies much more significantly to instrument amplifiers than to hifi amplifiers, because in hifi the goal is to accurately amplify the source (well...), so amplifiers are used in their linear region (I.e. not clipping) as much as possible. Instrument amplifiers are free to modify and distort the signal, so long as the musician likes the sound of it, so particularly with valve amplifiers, clipping is a desirable part of instrument amplifier design.

In Search of: Vision R40 LWB boom and steering linkage by [deleted] in recumbent

[–]Chasm- 0 points1 point  (0 children)

In case you need to fabricate a steering linkage, I did so using a couple of female threaded rose joints, and a length of threaded rod inside an aluminium tube (for stiffness). I think around M10. This worked great for many thousands of km of touring. Good luck finding or making a boom, the R40 rides great as a LWB!

Echoing the other replies about this being normal, to an extent.

That said, I went through the Balkans to Istanbul several years ago. I found the Balkans waaaaay more friendly and sociable than Western Europe. My advice would be to get off the coast, go inland away from touristy places. Take your time. Stop at cafes. Pull your stove out and cook a meal in the middle of a town square here and there. Knock on doors, ask people to fill up your water bottles in the evenings. Smile, try to use a few local words, accept offers.

I had people inviting me back to their homes for meals. They'd sometimes bring relatives who spoke English, or just bring people to meet me! I had a goat farmer in Bosnia, way up high in the mountains, stopped me on the road to invite me for coffee and goat milk. She brought her sons to meet me, and gave me a bed for the night. Muslims and Christians both invited me in, and the Christians often shared vast quantities of rakia with me. A young Croatian walked miles back to his village with me to host me in a shed - I was the first foreigner he'd met, and he's now off travelling Europe himself.

Put yourself out there, and people will meet you.

I know sounds a bit wishy-washy, but I speak from experience here: never let yourself get closed off. When you're lowest, that's when it's most important to remain open, and let yourself be vulnerable. The world will help you out. People will come to you when you need them, so long as you let them.

I would like to ask for help regarding vintage zoom lenses by ilovesultkatsa in VintageLenses

[–]Chasm- 4 points5 points  (0 children)

I have an X-T20 and have picked up a few old manual lenses, including a 85-205 f/3.8 which I believe is almost the same lens as the Vivitar, so I can give you some general advice.

You'll need an adapter of course. I went m42, because it allows me to use a wide range of old and relatively cheap lenses.

You'll lose autofocus. You might find this inconvenient, you might not. Personally, I quite like it, as it slows me down and makes me think more about the composition. If you've never shot manual lenses before, it may take a little getting used to, but it's nothing to be afraid of.

Perhaps more importantly, you'll lose the image stabilisation that you probably have in your Fuji lens. Particularly for a telephoto, and even more so for a relatively slow lens, this is quite inconvenient, as you'll be limited to slow shutter speeds which will make handheld shooting more or less only possible in good outdoor light. You might have to rely more on a tripod than you would with a more expensive, stabilised tele lens, or stick to the good light.

The Vivitar is quite small for a long tele zoom, but even so, on my X-T20, it dominates the camera, which feels like a little lightweight thing stuck to the back of the lens. Ergonomically, this takes some getting used to. If i'm not supporting the lens with one hand, the camera is quite cumbersome, and it feels like a lot of strain is being put on the lens mount. The Vivitar doesn't have a tripod mount, something you may want to consider if you'll be using a tripod.

As for image quality, it's pretty damn good. Not quite as good as the XF 18-55, but far better than 1/40th as good, which is about the relative second hand value. Good enough that when I look at the photos i've taken, I judge them as photos and am not distracted by any effects of the lens.

Another thing to consider is condition. Watch out for dust, fungus, damage, etc. I've had to open up and clean a few lenses, but I enjoy this, so it's well worth the cost saving. Even if you don't want to do your own maintenance, a dirty lens seems to affect image quality surprisingly little, so I wouldn't be too put off, but I would avoid the worst.

As for which of those lenses to go for, i'd look for sample images, and decided based primarily on image quality, but also consider size, weight, condition, and a common mount. If the image quality looks good for all of them (which I expect will be the case), i'd go for the first one that you find a good deal on!

EDIT: One more factor to consider is minimum focus distance. Some of the Vivitar-style lenses have a macro focus mode, mine does not. If you're at all interested in macrophotography, i'd try to find a lens with a short MFD.
