Cinestill C-41 Development Times

Chemical Reuse

Below you’ll find my table of development times for color negative film using the Cinestill C-41 kit at 102 degrees F. These notes should work with Arista C-41 as well since the instructions are nearly identical for chemical reuse. Heck, it might even be the same stuff, just repackaged.

Tips

It’s handy to print this out and save it in your lab for quick references. It’s also a good idea to put a piece of gapher tape on your chemistry bottles used for storage and mark how many rolls have been developed with them by a sharpie.

Rolls Processed   Time
0 new chemistry 3:30
1 3:34
2 3:38
3 3:43
4 3:47
5 3:51
6 3:30
7 3:59
8 4:04
9 4:08
10 4:12
11 4:16
12 4:20
13 4:25
14 4:29
15 4:33
16 4:37
17 4:41
18 4:46
19 4:50
20 4:54

Usage

The way to read this is not by how many rolls you are going to develop, but how many rolls have already been developed. For example, if I were going to develop 5 rolls with fresh chemistry then I would start at 0. The next batch will start at 5 and so on.

What are In-Ear Monitors?

In-Ear Monitors (IEMs), is a type of headphone designed to be partially inserted into a user’s ear canal by using form-fitting tips often made by a range materials such as rubber, soft plastic, silicon, and more. It’s also common to purchase custom molded tips to fit your ear canal. This typically offers the best results in comfort and noise isolation.

Facebook Page Analytics

with Ruby On Rails

I decided to flex my programming muscle and try something new. I’ve done Ruby for CLI tools and Chef cookbooks but never a Ruby on Rails (RoR) application. Much of the hype with RoR is gone these days but it’s been around long enough to be considered tested and somewhat mature like an old elitist hipster… If that makes sense.

tldr; Just give me the source

Description

The project was to create a Rails applications that provides analytics for the last 100 Facebook posts of a Facebook page. As a user, you should be able to login using Facebook, see a list of pages that you have authorized admin access to, and lastly see a display of the pages’ top 5 posts (out of the last 100) as well as a sortable table of the 100 most recent posts.

The World's Finest Audiophile Electronics

Now Live

I’m very excited to announce LosslessLife, a company focusing on the best high resolution audio gear. LosslessLife reflects the continuous hard work and commitment in the products it believes in by creating a voice to get the word out from the audiophile communities and to consumers.

It is often assumed by the average consumer that a higher price and/or bigger brand name results in better product. While this can be true to some degree, consumers are often paying more for a product’s marketing expenses when purchasing from large retail stores rather than receiving higher performing product.

Strict factors such as performance, output quality, and the overall craftsmanship of products must be met in order to make it to LosslessLife as the company name is synonymous with the highest level of quality.

In a market that is saturated with mediocre products, LosslessLife believes it’s success will be by educating consumers to make smarter choices when purchasing. We do the research for you and provide all of the facts in an unbiased fashion.

While many companies sell products which they claim they would use, LosslessLife only sells products it does use by it’s highly enthusiastic team with backgrounds in technology, production, and an affinity for music.

What are Planar Magnetic Drivers?

A Planar Magnetic driver, has coined a few other terms such as “orthodynamic” or “Isodynamic”, all of which mean the same thing (in regards to headphones). They can be described as the child of a dynamic and electrostatic driver, sort of… The best of both worlds, at least.

What are Dynamic Drivers?

A dynamic driver, sometimes referred to as a “moving coil” driver is the most common driver found in headphones. It is the same technology found in speakers around your home, but on a much smaller scale. This type of driver consists of alternating magnetic fields powered by a tiny wire coil (or a “voice coil”). As the current changes based on the sound playback, the coil reacts with the magnetic field and the lightweight diaphragm rapidly compresses and decompresses the air by pulling the diaphragm in and out from the ring within the driver to create the sound you hear.

What are headphone drivers?

Headphones are essentially a set of tiny speakers that sit in, on or around your ears and like all speakers, they have drivers. Everyone can agree that not all headphones are the same or created equally. But besides the superficial differences and the various features you may be offered such as noise cancelling and wireless capabilities, there are other more subtle differences that can make a huge difference. That subtle difference is determined by the type of driver used in the headphones.

Automate Your OS X App Installations

"To install, drag this icon..." no more!

I refined my original cask script for installing the software needed on multiple Mac workstations. The new version now allows you to configure parameters of the installation such as install path and which category of applications you wish to install.

The point of this tool is to help me configure (or reconfigure) workstations as needed by removing the manual work of finding the applications I always use online, unpacking, and copying to applications folder. That process becomes a tedious task when working with dozens of pieces of software.

Fork it for your own use on Github!
