I wouldn't call this 'rescuing' a photo via pp, to me that implies trying to salvage a photo you screwed up at the time of capture. This is planned post-processing, and viewing the hardware capture and software processing steps all as one big photographic process that work together for a desired result.

Advertising? Not a use for the photographer, but a bit of shiny and unusual bling would make the camera distinct when out 'in the wild'. Think of all the people who would walk into a store and say "I saw someone using a camera with awesome flashing lights all over it. I'll take two. No, make that three!"

Sales would've been through the roof if people had transparent hands.

They were in a boat, perhaps they thought polar bears can't swim.

Or it wasn't a frame filling closeup. You could safely photograph a bear with a 10mm, but it's not going to be a head shot unless you want to join the bear for lunch.

This is the faq from when smugmug acquired flickr (at least I do not believe it has been updated and is as I remember it back in April or so:

Together, SmugMug + Flickr | Frequently Asked Questions

Changes were inevitable, but the core is still essentially the same.

If flickr were to pop into existence today, people would probably be pretty ok with the idea of 1000 free photo uploads. I'm sure they considered some type of grandfathering option for people on free accounts and just opted for ripping off the band-aid in one go, possibly underestimating how angry people will be when you start charging for something they've been getting for free.

---------- Post added 11-02-18 at 12:11 AM ----------

Yup, I keep an external drive for important stuff at my in-laws and swap out every few weeks with a second external. Additionally, I don't format my memory cards until they're backed up off-site. This way if I'm not home during the disaster, the most recent photos are probably with me.

If losing photos involved disappointing anyone other than myself, I'd be backing up offsite far more frequently.

True, wikipedia has a list - List of largest stars - Wikipedia.

BUT! You'll notice our sun is used as the reference point for star size, much like photographers use 35mm/FullFrame as the reference point. I submit that the Sun - FullFrame analogy fits and all those larger stars are analogous to Medium and Large Formats.

A simpler camera

You'll never get two people to agree on what controls are important and should be included in a simplified camera.

I have longed for more built-in button customization, including complete re-mappings and selective disabling (less permanent than superglue & a black marker:D). Add in menu customization (especially hiding things you have no interest in accessing), and you could make your camera as simple as you want. Make these custom layout profiles shareable between users and programmed via a computer software interface. It's about time 'user modes' leveled up.

Not that I think everything you walk by needs to be photographed, but consider how the above quotes relate to one another. While I'm also a fan of keeping your eyes open for subjects already in flattering light, to me the point of artificial lights and modifiers is that you can make the light whatever you want (with small subjects). This can range from just 'correcting' tonal issues with the natural light or creating your own stylized lighting, but it especially means an interesting subject in unfortunate natural lighting doesn't need to be passed by.

Re: a mirror (or reflector/diffuser/etc), it's a tripod for the win here, with the camera on the tripod and the modifier(s) in my hand(s)/teeth/feet. Or (if your shutter speed can supoort one hand shooting) learn to focus manually with one hand...I can work the dfa100mm's ring with my right pinky for fine adjustments:D. Great thing about flowers is they can't run away from you, so you can take your time...

Lighting Control for Flowers

Nice idea for a thread, and great examples:). One flash in a little soft box can be so very versatile. Hopefully you will inspire a few flashed flowers:)

I've grown to trust my lighting meter and manual flashes, but p-ttl seems handy. If I had the equipment I'd definitely take some time to learn how to use it to see where or if it would help me. I know I'd love to have the HSS option that also comes with dedicated flashes.

This was a bare flash camera right and up as the main light on the flowers face. I probably overuse the starbust in the background thing, but it's nice that a bit of artificial lighting lets you expose for the sunburst and still put light wherever you want it.

Flame! by Brian Robin, on Flickr

Single small (but up close so relatively large) softbox to the left and somewhat behind the bloom to bring out a bit of the backlit colours like several of the other photos in the thread. This was outside, in a makeshift studio. In other words, I used a random blue object for the background, in this case a decommissioned hospital item labelled "bowel irrigation cart". The blue was pretty, I don't judge the former use.

Hellebore Bud by Brian Robin, on Flickr

Here's where HSS would have been lovely. No, an ND filter just wouldn't work, unless you have one I can attach to the 10-17mm fisheye:). It would have been nice to have more choice on the aperture than x-sync allows as I wanted to keep the sky detail. But again, flash to the rescue as it let me light up the foreground however I wanted. Advantage small things like flowers - it's relatively easy for a small speedlight to overpower the sun if it can be a few inches away from the subject:)

From their announcement:

"The Irix 150mm f / 2.8 Macro 1:1 lens has been sealed in key points (the front element, the Focus Lock ring, the focusing ring and bayonet), making it suitable for use in the harshest of weather conditions such as fog, rain or snow."

Plus, it has neutrino coatings, which is just high tech sounding.

It was looking like a great year for these butterflies, with more than I'd usually see flying in the spring. This is the only larva I found all year. It probably doesn't help that they'll feed on Queen Anne's Lace and there are several fields full of the stuff so they become the proverbial needle in the hay stack.

Another great thematic thread Peter:). I'm pretty fascinated with the whole insect life cycle, and the past few years I've raised many Lepidoptera from the egg or caterpillar stage for both ID purposes and to photograph the life stages. I may have put these two on PF before, I'm not sure (some lighting info is on Flickr if you follow the link;))

A Hyalophora cecropia caterpillar (giant silk moth). I've bred them the past couple years, great fun! This is the 4th stage of caterpillar, one more to go and then pupa time.

Real-time AI-driven evaluation of my photos. Preferably with a points system and a (mandatory) audio feedback in the style of cheesy Android puzzle games. This way I, and everyone around me, would know how awesome I am when my camera shouts:

"Nice Bokeh!!!!"
"Rule of Thirds and Complimentary Colour COMBO!!! +1000"

That would be a game changer for me. Otherwise, I'm happy with my k5iis, it does what I need. When I eventually upgrade, I'll mostly be looking forward to minor improvements and hopefully a few whiz-bang high-tech features I'm seeing in other models that would ease my workflow (the stuff that's nice but not mandatory to have).

Questions about the D-FA 100 f/2.8 WR
Posted By BrianR

It's not great at tracking, no. When I'm able to brace myself well, I've still had handheld AF success down to about 1:1.2 magnification. I'm more likely to use it above 1:1.5 though.

Provided I have something of contrast under the centre AF point that's in a stable position, I rarely ever experience any hunting. This is usually what goes wrong when trying to AF for a candid portrait resulting in the lens going for a spin- me not able to track a subject. I'm not 100% positive, but I'm reasonably convinced the F2.8 sensor in the centre of my k5iis helps with an accurate focus lock, even in pretty low lighting, so I usually stick to the centre up close.

You're always limited to where the focal points are, moreso if you're only using the centre, so if you want to put the focal plane between the mushrooms stem and the leading edge of the cap you really have no choice but manual. I'm a big fan of manual focus (I love my rail!), it's pretty much always applicable for macro or close-up work and quite often superior to AF, plus saying otherwise would make the years of often frustrating practice manually focusing seem like a waste:), it's a necessary skill for macro. However, AF can be reliable and quicker in the right situations, worth exploring to see if it's workable.

I'm always setup to use back button focus, so the exif is no indication if I used AF or not, but this is exactly the sort of photo where it would have been dandy and likely what I used - something reasonably flat, with the light edge of the slime mould over the darker bark at just the right place for AF success:

Up close is where the focus throw is really long, and here it's excellent for fine control. At 'normal' distances, it's a fairly short throw, I estimate turning the ring about 1/8 of the way around (45 degrees) will take you from infinity to about 3ft away. That gets tough to manually focus (for me anyway!). On the plus, the autofocus is very fast at normal working distance, unless it misses and decides to go hunting down to the minimum focusing distance, then it takes ages to get back. As camera bodies AF has improved, this is becoming less of an issue since missing is less common (also follow BigMackCam's advice above:)). Using back button focus with this quick shift lens can make recovering from an AF miss pretty fast.

It will most definitely work for your intended usage. I use mine (the non-WR older version) for candid portraits and also as a general compact mid-tele walk around lens. However, I primarily own it for its macro capabilities, aiming it at people is a secondary use for me and there are probably better options for a dedicated portrait/event/people lens.

5000 pixel "line camera"
Posted By BrianR

I gave the Slit Cam program a quick try. This was a video of a Monarch caterpillar pupating, there's a still image on the right and the full video is below for reference. It's 5 minutes and not very exciting unless you've never seen this sort of thing before or just find insect metamorphosis fascinating. There's no cheery or uplifting music to keep you entertained. If you sit through it, you're not allowed to ask me for your 5 minutes back:D.

The top left is taking a vertical 'slit' running through the centre of the video (straight through the cremaster). The leftmost column of pixels is this slit at the first frame, the rightmost column is this slit at the last frame of the video. As time marches to the right, we can see how the last instar's larval skin is drawn upwards. There is much bobbing up and down during the process making the waves:D. It's kinda neat how it gives you a measure of the frequency of this bobbing during the transformation.

For the bottom left, I took a horizontal slit about 1/3 from the top of the video. This captures the skin from the last instar as it's sucked towards the top and passes by the 'slit'. Near the end, the pupa is bobbing up and down enough to get above the slit, and then it settles down. It's rotated sideways 90 degrees.

I have to say, this is a pretty fun way to represent a literal slice of a video into a single 2-d, static image.

A downside is any change you make after reverting erases all the steps that had come after. Or maybe that's a good thing if you totally screwed up and want the record cleaned:).

There is also the "Snapshot" option which lets you save the photo at various history states, or Virtual Copies if you wanted to fork alternate edits out. Neither really preserves the full history panel, but they can be handy.

What wouldn't work? You could rotate very slowly and read off the camera very slowly. No need to stop at a 3:2 format, spin right round and cover 360 degrees over the course of a day. Or keep spinning for a full year and make the worlds longest panorama timelapse. This could be done with any camera constantly clicking away and just take slices out of each image, but it has a little more charm if the camera hardware is more made for it.

Nice link! I hadn't seen this fellows work before, but this is exactly the sort of thing I had in mind I had in mind. It's an interesting exploration in how you can capture a dynamic and changing scene onto a static 2-d image.

I've seen home made scanning backs before and have a scanner sitting around waiting for me to build up the drive to do something like this with. I have an app for my phone that simulates a slit-scan camera, but it's shockingly abysmal. I suppose it's about time I try to mimic a slit-scan with a dslr using a video capture*.

I ran across an interesting flea bay listing for a DFA100mm macro attached to a Mitsubishi Rayon Camera MKS-5000-40 (I have absolutely no affiliation). The camera it's attached to is a 5000 pixel camera. Not megapixels, just pixels, all arranged in a straight line. It's also B&W.

I hadn't heard of this type of camera before, here's an article about "Line Cameras": Line scan cameras - Quality right down the line | STEMMER IMAGING. It's kinda interesting, you can aim it at a conveyor belt and watch stuff go by. Scientific and industrial applications await, but you start imaging all sorts of fun applications for it- attaching it to a motorized panorama head for a timelapse landscape panorama. Filming cars, people, birds, or anything else that wanders by going by. Aiming it out the side of a car and scanning a street as you drive by. Panning across someone while they mostly hold still but distort an arm or leg...etc. If I didn't already have a dfa100mm macro, I might be tempted:D.

I thought others might find it neat, and we could use a few more posts to hit the k1mkii giveaway so...:D
