Color E-6, C-41, and B&W Film Processing by Mail

Mail your E-6 Slides, C-41 color negatives, and black and white negative film to us to be developed and scanned. We handle all film development, scanning, and printing in house in our darkroom and do not send film out to be handled by a third party.

Step 1 – Start Your Order Online

If you haven’t already done so, please create an account with us by going here and registering. If you’ve already registered, then log in. Please be sure to have your billing and/or shipping information filled out in your account details. This is important so that we can match your film up with your account when it arrives.

If you prefer to do it the old fashioned way or want advanced control over the process, you can also download our order form here, print it out and send it in with your film.

Step 2 – Shop and Pay Online

Select the services you want in our online store

All film services are sold à la carte, so please be sure to select the correct number of frames you’d like to have scanned in and/or post processed for the type of film you’re sending in.

If you want us to scan your film in, please see the example scans we provide with most of our film tech pages.

Our default film scan file format is Adobe DNG, however, you can request other file formats like TIFF or JPG if you really want them.

Example Costs

A roll of 120 C-41 film shot in a 6×6 camera will be $6 to process, and $4.20 (12 frames x $0.35 per frame) to do a straight scan for a total of $10.20 plus the cost of return shipping your film to you.

A roll of 36 exposure 35mm C-41 film will cost $6 to process, and $12.60 (36 frames x $0.35 per frame) to do a straight scan for a total of $18.6 plus the cost of return shipping your film to you.

Return shipping your film will vary depending on where you are and how many rolls you send in at a time, but it’s typically less than $5. The cost for return shipping your film to you is calculated during checkout.

Step 3 – Mail Your Film to Us

If you shopped and paid online, just drop your film into a padded mailer and mail it to:

Simple Photography Services
ATTN: Film Developing
1390 N. McDowell Blvd. Ste. G, PMB274
Petaluma, CA. 94954

Please make sure the return address on your mailer matches the billing or shipping address in your account details so that we can match them up when it arrives. Please do not send film to the address at the top of this page as that address does not have mail service.

If you didn’t shop or pay online or want custom film development, then download our order form here, print it out and send it in with your film. If you already paid online, just indicate so on the order form.

Technical Information

Please check the list of film tech pages here for exposure guidance and technical information about each film that we’ve reviewed. If you have questions, just ask.

Film Scan Technical Information


All roll films are scanned at the same resolution. Our film scanner has a 6000×4000 pixel native sensor, so all film is digitized and delivered to you at that source resolution.

File Format

We deliver Adobe DNG files of your scanned roll film. Imagine that! A digital negative of your film negative. If you’re an Adobe Lightroom user, just add the scanned DNG files directly into your catalog and have the full power of Lightroom’s Develop Module at your fingertips to do as much or as little post processing as you desire. For a hybrid workflow, it’s the best of both worlds. If you don’t use Lightroom and none of your software supports reading Adobe DNG files, we can also provide your scans as TIFF files, or optionally, jpeg files.

The Adobe DNG files contain a positive image of your negative film in 32 bit floating point scene referred linear light space. Basically, the highest supported sample precision you can get. Your software will need to support at least the DNG 1.4 spec. Most recent versions of Lightroom do so with no issues.

We linearize the film’s characteristic curve via a variety of well known contrast indexes and can scan film in and get it linearized over a pretty wide range of emulsion contrast levels. The software tool that we use to do this linearization/color space transformation is called Simple Image Tools and is custom developed specifically for scanning in and digitizing film. Most images run through this tool are tagged with the tag “simple_image_tools” so you can search most image sharing sites for that tag to see output from the tool. It’s really good and I’m constantly working to improve it, as I use it for all of my own images. See images on Flickr that were generated with this tool. You can also check out the film tech sheets section, as I make sample DNG files available for most of the films listed there.

At some point, I may release this tool for usage by others, however, since it’s currently actively being revised and improved upon over time, for now, the only way to get scanned images with this tool, is via Simple Film Lab. The upside to this workflow is that it actually doesn’t matter what scanner you use as long as you can get raw untouched sample data from the scanner. All images are conformed from the raw scanner sample data to the ProPhoto color space that is native to the Adobe Digital Negative specification via a generated profile for that film/scanner combination.

Scan Delivery

Straight and basic scans are delivered via a link to download the files to the email address for your account.

Film Delivery

After scanning, your developed film is cut and sleeved in printfile film sleeves then returned to you via the shipping options selected at checkout. We use stiff cardboard photo mailing sleeves for delivery, or a flat box for large processing orders.

Turn Around Time

This can vary a lot depending on how busy we are, however, normal times are 5 business days from the time we confirm receipt of your film for delivery of your scans for most orders. If you send in a large number of rolls at one time, it may take longer.

Limit of Liability

Even though we take every precaution and treat your film as if it is our film, Simple Photography Services (and Simple Film Lab) is not legally liable for anything that happens to your film while it is in our possession. Yes, we recognize that this sucks, however this policy is standard business practice. However, with that being said, we are customer service oriented, so even though accidents can happen because nobody is perfect, we’ll do what we can to make things right if that ever happens. Hopefully it never does.
