Disassembling the Ricoh GR for sensor cleaning

One of the great things about Flickr is that there are groups of people with similar interests who not only post images, but also have discussions about issues with cameras and other aspects of photography. I’ve been a member of lots of groups on Flickr since joining in 2004 and currently I’m a member of a few Ricoh GR groups. One of them has an ongoing discussion of the Ricoh GR’s problems with dust and I’ve been tracking it: how do/did handle the dust issue?. The other day one of its members, Jamie Collinson, posted a link to a post he’s written on disassembling a GR and if you’re a GR user (or even if you’re not) it’s worth taking a look at and bookmarking for possible future use:

A guide to disassembling the Ricoh GR for sensor cleaning

Many people have had dust issues with the Ricoh GR. It’s both a cult favorite camera and a rather fragile beast. A theory is that it’s retractible lens (the lens telescopes out of the camera when its turned on, then retracts into the body when it’s turned off) is acting like a bellows and pulling dust in when it moves. Another is that the seals on the camera aren’t doing their thing.

If you have a GR and you’re not sure if you’ve got dust on your sensor, the standard test is to stop down (close the aperture) to f/16 and focus on and shoot a clean white wall or a clean sheet of white paper. You’ll see the dust spots (as hopefully differentiated from dirt on the wall or paper). Or, you may have seen spots in clear skies that are shot at small apertures.

I don’t think its worth doing this surgery for a single dust spot when you can easily clean it up with an image editor like Lightroom but people who get dust in their cameras generally have a number of spots and that can be a tedious clean up process (in software).

If you generally shoot with an open (wide) aperture you’re less likely to see the dust, unless you’re really loaded with it, it generally only shows up at smaller apertures.

It’s worth it to have a look at Jamie’s post just to see what the inside of the Ricoh GR looks like, he’s got great pictures.

The only thing I’d add to his otherwise excellent post is a technique I learned doing surgery on early Macintosh computers (mostly powerbooks and early MacBook Pros) with small sets of different sized screws that might get mixed up. List the steps of the disassembly on a piece of paper and pile the screws next to their corresponding steps. For example, in his post with 7 steps, one might divided a piece of paper into 8 boxes, put a number in each box and put the corresponding screws in a box. Just make sure to not move the paper.

Project Apollo Archive


The Lunar Rover on the moon on the Apollo 15 mission

NASA has put another photo archive up on Flickr: the Project Apollo Archive with images from most of the various Apollo missions including all of the moon landings. Wow, it’s a lot of fun to browse through. Not everything is incredible but there are gems buried in over a thousand images. And, the images are free to embed elsewhere if you’re a member of flickr.

Flickr Commons, participating institutions

Flickr Commons Participating Institutions

It started with The Library of Congress in June, 2007 and has grown considerably since then.

The key goal of The Commons is to share hidden treasures from the world’s public photography archives.

And they’re doing just that.

I could have posted a lot of stuff here but I hope anyone who reads this will follow the links and poke around. If you have a blog, all of these images are easily embedded. I like to give some context when I use things like this but it’s not always possible.

Have fun.

Sharing photography online (or not)

Things I Learned After My Photo Hit #1 on Reddit, and Why I Probably Shouldn’t Have Posted It

Kris J B posted an interesting story at PetaPixel about the balance between posting images online freely and not posting for fear of theft. The comment thread is worth looking at as well as the detailed story.

I had a similar experience with this image which I described here.

In the end, I continue to post images to Flickr and post embed of them here, as well as allow my contacts on Flickr to embed my images elsewhere. Have I been ripped off? Absolutely. Do I care? Absolutely. Will it stop me from posting images online? No.

Flickr Turns 10

Flickr Turns 10: The Rise, Fall and Revival of a Photo-Sharing Community

A well written history of the photo sharing site flickr of which I’ve been a member since 2004, just after it launched.

For me, flickr continues to be a great online community and I’ve made many friends there. And, I started posting images there for embedding here because I was attempting to save bandwidth but now I’m enjoying embedding and sharing other people’s images as well as my own. Few other services in flickr’s category allow this.

While I’m not crazy about Yahoo’s site changes, flickr remains an important part of my online activity and identity.

The social network is broken

The Facebook experiment has failed. Let’s go back.

This is a well written essay on deep, structural problems with Facebook by a Medium user named jeswin.

The social internet seems to have tipped into one, large popularity contest and the tools each platform uses to allow users to “like” and/or “recommend” content they like have become too important. It’s certainly understandable that platforms like Facebook, flickr and twitter and others want more users, more posts, more interaction, more action, but is enabling competition for popularly the only way to do this?

This reminds me of a post I wrote in 2007 on flickr explore, flickr’s system of promoting popular photographs. It must be a well known idea among social platform builders that to attract more users, more content, more interaction, the platform should include tools for faving, liking, commenting, and more and a black box to compute which posts, images, comments are the most popular. This, at least as it is now implemented, seems to be both an attractor and a curse.

I’m sticking with flickr

One thing that many who are reacting to the big changes in flickr haven’t taken into account is this: flickr is a community, not just a place to post images. Over many years I’ve made hundreds of friends all over the world on flickr, have been involved in some great groups and group discussions, and have used flickr as both a place to host my images but also as a place to hang out.

Flickr was the first large scale social community on the web although not everyone on flickr used or uses it that way, many people do.

What I’ve realized in the past day is that changing the wallpaper does not break those connections, and because I interact with flickr via Reeder, an RSS feed reader, I don’t have to navigate the black mess that is the current user interface as much as many do.

For me, the biggest violation that there is no excuse for is that they did this overnight with no notice to us. Had they rolled this out incrementally and gotten feedback on each change the entire fiasco would have been avoided. For me, the process (the way they did it) was worse than the product (what they ended up with) which is bad enough.

The site is a mess visually but we have to admit that at least some of this is a reaction to a big change in something we used daily for many years. I’m not defending the look or the way they’ve changed it but most of the old functionality is there if we dig for it. It’s not right yet but it’s a web site and it can be changed and I’m pretty sure it will be changed.

The other concern for me was what looked like a price increase for what used to be called “pro” users but in fact, that has changed and our pro accounts will be grandfathered in and the price has actually gone down. Check out your account page if you’re a paid account holder, it’s been changing in the past 24 hours as they’ve listened to feedback.

My pro account was due to expire in May, 2014 and I just bought another two years (for $44.95). They won’t charge my card until May of 2014.

I don’t like the look of the site as it is but I do like flickr and I have a community of friends on it that I’ve known for close to ten years and images embedded here from my flickr account and from other people’s. That’s meaningful to me and I don’t want to give that up.

Flickr update

The photo sharing site and service that I use, flickr has made a major update to its service and site.

I’ve been using flickr since 2004 and I’ve stuck with it even after Yahoo bought it and let it dwindle. Certainly the amount of time I’ve spent with the old user interface makes it difficult to look at any change with an open mind so I’ll reserve ultimate judgement for a while. But, Yahoo is attempting to bring itself and it’s popular properties back from the dead and this flickr update is part of that process (as is the buying of blogging platform tumblr.

My quick take: Too much information, too tightly packed. Here’s what my home screen looks like now: Richard-.

I hope over time they fold in some customization tools that make it possible to display a bit less information on one’s landing page. We’ll see.

Chris Wetherell Reflects on Google Reader

Google Reader lived on borrowed time: creator Chris Wetherell reflects

This is a great history and commentary from one of the creators of Google Reader.

If there were things that went wrong, then there is a lot of positive things that came from Google Reader, Wetherell said. He believed that one of the main reasons why Google Reader could exist was because companies and entities with completely conflicting agendas came together, supported RSS and other standards. Google, MoveableType, Blogger, WordPress, Flickr and several other web-apps believed in creating RSS feeds for easy consumption. “In the end it helped the average users,” said Wetherell.

But all that is behind us and we might not see similar altruism again, Wetherell theorized. I agree with him. If in the early 2000s, Web 2.0 companies were building platforms that wanted to work with each other, today, we have platforms that are closed. We live in the world of silos now. Twitter and Instagram have broken up. Facebook is the Soviet Union of the modern web. The new systems don’t offer RSS or feeds.”There is no common language of sharing,” he bemoans. And rightfully so! And unless we have web giants speaking the same language of sharing, there seems to be no future of aggregation.

This last piece is rather depressing and it doesn’t speak well for the future of RSS which will only live on if it has broad acceptance and use.
