I’ve prepared a good edit of a photo very similar to the one of Chris Cheng in the recent blog post.  I’m going to post it here, and then subject those of you still reading to some discussion of what I did to it, and why.

(more…)

Yeah, that joke has been done to death.

A week and a bit ago, a bunch of 1960s Jay Kay Klein index prints reached my house (via The Eaton Collection at the University of California Riverside, Fred Pohl, Chicon 7, and Steven H. Silver, if I understand the path correctly).

And many gigabits of files have been created.  I did not in fact scan every single photo I was sent, but I scanned too many of them.  At too high a resolution.  And mostly worked too hard cleaning up the dirt and grunge on the negatives when the prints were made.  And didn’t clean them up enough.

What I did do is transcribe all the ids on the back of the photos (occasionally running to 20 or so people identified on one photo) into IPTC keywords, so anybody importing these images into a “Digital Asset Management” system (yes, a “DAM system”) will get a pretty good index of the people shown.

I’ve sent over 600 display-resolution JPEGs back to Chicon; I understand they’ll be used in a display in the Concourse, along with scans of the other 2/3 of the original box of prints that two other people worked on.  (I turned down the chance to get a second box here; given when I finished, this was a wise choice.)

The prints I had were mostly from the 1962 (Chicon 3) and 1966 (Tricon) Worldcons, and included Heinlein receiving his Hugo award for Stranger in a Strange Land and E. E. Smith in costume as, I suspect, a Lensman.  Also Avram Davidson, and Lloyd Biggle, and John Brunner, and James Blish, and Sam Moskowitz, and John W. Campbell, and Poul Anderson and Gordy Dickson and Fred Pohl and Algis Budrys and Randall Garrett and Walt Willis and Leslie Turek and Bob Silverberg and Harlan Ellison and the Asimovs and the Sturgeon’s and Phil Farmer, L. Sprague de Camp, Jerry Pournelle, Jack Williamson Roger Zelazny, Chip Delany, the del Rey’s, the Ballantines, Beam Piper, Phil Klass, Gene Roddenberry (who was at Tricon previewing Star Trek for the fans), Jack Williamson, Jerry Sohl, and many others.  1962 was just a decade before I got into fandom, and I’d seen lots of book-jacket photos, so many of them looked familiar.

I wish I could have had access to the negatives.  I couldn’t have done nearly this many scans from negatives this fast, but I could have gotten much better images from the negatives than from these old index prints.

Not my usual thing, but I was invited to come shoot a roller derby bout, and it sounded like fun.

This is my piece of the panel from Minicon 46 (as prepared; this is my notes and example pictures, rather than any sort of actual record of what I said). Dave Romm’s gallery is here.

Effort for quality

Effort is time or concentration, weight lugged, money, whatever. I’m going to talk about things that are free—costing only time and concentration.

Quality is completely subjective. Even on very basic things—should something be in focus in a picture? Anything? Sometimes a photo works without even that.

Photos have different purposes—memory, art, communicating to others, history, etc. The idea here is for you to take the photos YOU want to take

But, basically, this is about how you can work harder for better photos—most efficiently.

Equipment

This is about using what you have, not about spending lots of money on fancy equipment.

Learning to see

Looking at a photo, which just sits there and is flat, causes the human visual system to behave differently than when we’re looking at a real scene. To take better photos, you need to learn to see what will be apparent in the flat photo. You need to pay attention to the edges, and to juxtapositions at a distance (which we mostly ignore live, but become obtrusive in a flat static photo; the “pole growing out of the head” is the classic example).

Digital photos are free. Experiment. Deliberately try things changing one variable at a time. Examine the results and see what you can learn.

Picking and choosing

Big wastebaskets make good photographers. Shoot heavy, display light. (No, I’m not very good at practicing this.)

Framing and Cropping

Decide where the frame boundaries are. And don’t be afraid to crop tighter in post-processing.

Photos of a person in isolation are sometimes very nice, but you don’t need that many of any given person. Shots of them in an environment are more interesting, or interacting with another person.

Composition is a graduate course, which I’m not the person to teach. Just do what looks good to you.

Variety

Whole room, small groups, couples, individual portraits. The wider shots are much the hardest—or maybe that’s individual.

 

Moving

Moving towards, away from, and around your subject changes how it looks in relationship to everything else in the frame. Think about this, experiment with this. You can get rid of distracting backgrounds, or introduce interesting relationships. Don’t forget up and down! Very often, a photo looks better from a bit below the eye level of the subject. (The technical term for these relationships between objects in the scene is “perspective”.)

Eyes

Mostly in people pictures you really really really need to have the eyes. Preferably open. Ideally, not blocked by the glasses frame.

Focus

The time it takes the camera to focus is the biggest part of the delay between pushing the button and actually taking the picture. Most cameras let you pre-focus by half-pressing the button (and holding it). Then you can take the actual picture, with much less delay, by pushing the button the rest of the way. (DSLRs also focus MUCH faster than P&S, because they use a completely different technology to do so).

Review

It’s easy to check whether you got what you wanted, these days. Remember that you have to zoom in quite a bit to accurately judge whether the picture is sharp.

Posing and directing

Getting people to cooperate with you can help. Another presenter is much more into this than I am, and I know will be covering it, so I’m not.

Flash

The built-in flash is lousy. For nearly everybody, going beyond that is a huge step up in commitment (money, weight). I’m going to ignore techniques with more advanced flashes—that’s a different panel.

Fill flash.

Short range.

Red-eye, but easy to fix in post, even in-camera these days.

Long-term projects

It’s often interesting to see something over time. If you’ve got old photos of a house, find where they were taken from and take new ones, and keep taking new ones. Take portraits of a person every year (ideally, including a similar simple setup in each session, so that the change is as much as possible in the subject).

Examples?

Post-processing

Cropping

Mostly to go on record as agreeing with DavE Romm.

Brightness adjustment

This is very simple post-processing.

Color correction

Often as simple as clicking a tool on something of a neutral color. Highlights on black clothing sometimes work. Gray hair sometimes works. (The worst cases get exceedingly nasty, but most are simple.)

This one came out of the camera fairly wonky, for no apparent reason (flash color is good, and this was bounced).

Software

Picasa, Photoshop, Lightroom, Bibble, Aperture, Gimp, Elements, iPhoto. Can be very expensive. The absolutely free stuff has uglier workflows. The decent stuff has a learning curve.

Sharing

Online

Facebook, SmugMug, Picasa, Flickr, Zenfolio, many. Doesn’t impose on anybody. Can control levels of access if people are willing to help (get accounts).

Don’t let valuable data exist only there, though—annotations, especially basic identifications.

Privacy.

Portable devices

Phones, pads. Can control access, and easy to point out a photo. You get to watch.

Hardcopy

Inkjet, photo paper, other. Album, postcard, framed on the wall, book. Target, Walgreens, Costco still do digital photos. Smugmug and Flickr and the online peopel will sell you prints mail-order. Inkjet printers are very good. They’re more expensive per print, but quick turnaround can let you get work done much faster.

The Future

You need to prepare your photos for the future.

EXIF

Time. More and more, GPS coordinates too.

IPTC

Writing on the back of a jpeg file. Do it in the master, so it shows up in all the derivative works.

People, places, events, dates.

Backups

No digital medium yet devised does very well on benign neglect; a digital archive needs to be actively managed.

Keep a set of backups away from where you keep your primary copies (if nothing else, sick ‘em in a drawer at work). The big benefit of digital is that a copy is just like the original; exploit this!

Online backup may be workable for you. It’s automatic, and gets you an immediate off-site copy.

Copying to an external disk is probably the best overall choice right now. Have at least two, preferably three, backup disks; if lightning strikes while writing your new backup over your old backup, your can lose your original and all your backups at once. So overwrite your oldest backup while the newest is not connected.

Optical disks can be good, but they’re rather small, and the lifetime of media varies a lot. Use good media, ideally MAM gold archival or equivalent. They are a pain to make and to check, especially if you’re making multiple copies.
