This past weekend I was fortunate enough to take a workshop on some historical photo processes at pcnw.
You can check out a few of my scans on flickr.
For both of these processes you apply the chemicals necessary for photosensitivity by hand on paper.
I already like making photo prints by hand, and I think this lends even more to that process. As a 'modern' photographer, I hate to admit that I like even the visible brush marks, but I really do!
The cyanotype process is especially interesting to me. This was originally used for reproducing drawings, and is how blueprints got their names (they were cyanotypes).
There are also some incredible early images by Anna Atkins in 1843 using cyanotypes for images of seaweed and algae.
Yes, the chemicals are toxic, but seemingly less-so than almost any other photo process?
The 'developer' is just plain water...
You don't even really need a darkroom for this process, just no UV light. And to develop, you can use the sun (though it may be unpredictable).
Exposures take a long time (20 minutes), but, that's par for the course here.
Once you coat the images, it's pretty smooth sailing.
I honestly like the look of this process more than cyanotypes... But, it feels a little heavier. It requires a real fix, and thus an archival wash... It's more like making a silver print.
Even though I think my cyanotypes weren't especially successful, I feel like it is a process I really enjoyed and would like to explore more. The strong blues don't work everywhere (although you can modify the tone a bit with other bleaching/toning processes.)
Look for more here or on my photo site on that subject :).
In this post I'll be comparing cloud hosting costs, which I'm sure will be hopelessly out of date in just a few months.
I'm writing this post to try to solicit feedback on cheaper file transfer options. If you have any advice or feedback, I'd love to hear about it!
Maybe it should have been obvious, but I've been somewhat surprised at the high cost of transfer vs. storage when you start talking 10s of terabytes.
For example, storing 10TB of data in S3: $302.60, transferring 10TB of data out of S3: $921.51.
I've also been (pleasantly) surprised at how aggressive the AWS/CloudFront (CDN) pricing is -- at $0.085/GB (US only), it appears to be the cheapest way to get data out of AWS. It's cheaper than both S3 directly ($0.09) and even cheaper than serving directly from an EC2 instance (also $0.09). This is kind of amazing considering all the benefits of the CF service vs. doing it yourself, or even S3.
I've been working out the details for a SaaS app that doesn't use a lot of storage, but has the potential to have a lot of subscribers. So, it will use say 200MB of storage, but need to serve that data potentially 50,000 times each month. The S3 costs are neglible, a few cents, but even the cheapeast CF tier (US only), we are talking $870.40/month.
I love the CloudFront feature set and service and will continue to use it where it makes sense.
For this app, I will have a hard time being competitive with other apps in this space with those costs, so I've been looking for cheaper solutions. Below is a list of what I've compiled. I'm not considering any "free tiers" for the comparison. These are great for development/etc., but I think not relevant in an ongoing cost comparison.
|Google Cloud Storage||$0.12|
CloudFlare is a pretty full featured CDN that actually even offers a "free" tier.
I signed up for a "pro" account to test it out. The problem is that even for the pro and business levels, there's absolutely no record provided of file access. That requires an Enterprise/Custom plan, where the pricing is determined by the sales team. I haven't yet made a call to a sales rep to determine what final pricing would be for my use case.
The other tricky thing here is that I still need to separately maintain and pay for an origin, the costs of which are entirely determined by how effectively CloudFlare can cache my content. What I mean is, if I put CloudFlare in front of CloudFront, and I'm only getting 50% hit rate from CloudFlare, I'm still paying for $435/month from CloudFront on top of what I'm paying from CloudFlare (that's a lot of CFs).
From what I can tell, they don't offer a straight cloud storage solution, but their "Most Popular" plan features 3TB of data transfer included for $20/month.
This works out to $0.00666/GB. Of course, I would like some basic redudency, so, say two machines and a load balancer, works out to about $0.01/GB/month? (($20*3)/6000), which is by far the cheapest I've seen.
Of course, there's quite a bit more there to build and manage.
The CloudFront pricing page does mention that you can reach out for reserved pricing if you commit to 10TB/month for a year.
Again, I'm looking for feedback and suggestions for a cheap, reliable file hosting provider.
I just finished my final project for Black and White Photo II at PCNW.
I chose to focus on Pike Place Market here in Seattle.
I spent quite a bit of time there! It was really great to get to know the space, people, and community so well.
The project was a ton of work, and I still feel like I could have used another month printing and editing. While I feel like I will continue to work on and develop this project, I'm really happy at where it ended up and was proud to present these images to the rest of my class.
These were all shot on an older Rolleicord, Kodak TMax 400 film, and printed on Ilford Warmtone Glossy paper.
It's been a lot of fun doing it and I'm really proud of what we've put out there. I can't wait to see how it goes from here.
If you haven't yet, please give it a listen, and please send us some feedback!
Thanks to some really amazing Seattle photographers, I've recently started shooting pinhole (photography without a lens!)
While you don't need to buy a camera to shoot pinhole, I think the Holga 120 Wide Pinhole Camera has some nice features and is worth checking out.
I put together my first YouTube photography video with a quick review and intro for the camera.
Please let me know what you think, and subscribe to my channel if you'd like to see more.
You can see some of my pinhole photography on my portfolio.
