Tech Blog: Colorspace, File Formats and Untagged Files

Have questions about digital printing? How to get images to us? What type of file to send? We have tried to start simply and move onto the more complex questions. If you have questions regarding any of this or just want to review the process with us, please call or email us! First things first… You can upload us files here and you will see this screen from Hightail. You can drag and drop your images for upload to us.

Do I send Jpg, tif or psd? Raw?

You can send us any of the above. We have provided some details below about the difference between each type of file.

Raw are the proprietary file from the camera manufacture. Some examples are: Canon (.crw, cr2), Nikon (.nef, .nrw), Sony (.arw, .srf, .sr2), Pentax (.pef, .ptx).  Raw files hold the most data from your digital camera and are the easiest file to adjust exposure, contrast, white balance and other fine tuning. We can edit your Raw files however this requires an editing charge.

JPG is best for web use, but still can be printed from if it has high enough resolution and was saved at a high enough quality. (80+ in Lightroom, 10+ in Photoshop).

PSD is an Adobe Photoshop proprietary format. It can handle all of Photoshop’s features, but has some compatibility issues with non-Adobe products and Lightroom. PSD has a 2gb files size limitation.  Due to the compatibility and size issues, PSD has been (or should be) replaced by TIF by most photographers.  We prefer TIF.

TIF is one of the most universally accepted formats. It can be opened by most image editing and page layout software. TIF supports all the same things as PSD and has a larger file size limitation (4gb).

Ultimately, just send us what you have and we’ll figure it out. Got layers, send us those too. We can always provide assistance with your files or if you want to sit with one of our Digital Technicians and review files in person.

OK, so a tif  file, 16bit or 8bit?

Either one is fine. Whatever works for you.

What color space should I sent it in? AdobeRGB98, sRGB, ProPhotoRGB

You can send us files in any of these color spaces. You should be working in either AdobeRGB98 or ProPhotoRGB to begin with. sRGB is meant as a web colorspace, anything you upload to your website or facebook should be in sRGB.

As far as AdobeRGB98 or ProPhotoRGB goes, it could go either way. ProPhotoRGB is much bigger than AdobeRGB98 and can produce more colors. However, you must work in 16bit with ProPhotoRGB otherwise you can end up with posterization effects (banding). The other down side to ProPhoto is it includes imaginary colors. Yes, I said imaginary colors. They (Kodak) made the ProPhotoRGB color space so big that 13% of the colors included do not exist in the real world and are not visible colors. This can lead to color issues when printing. Some colors will become over-saturated or will be estimated to its nearest in gamut color and can cause banding. Even the best printers in the world can’t print imaginary colors.

AdobeRGB98 is larger than sRGB, is easily printable by commercially available printers and includes no imaginary numbers. Its not perfect, nothing is, but it is the standard most of the photographic world uses.

If you have a gray scale file, that is fine as well. Gray Gamma 2.2 will do just fine.

What about CMYK?

Leave that to the offset printers. If you send us a file with a CMYK colorspace we will convert it to AdobeRGB98.

What about an untagged file?

If you send us a file with an untagged colorspace you will get a call from an angry elf… just ask Ron Cowie. Again, you can just send us what you have and we’ll figure it out. Following our recommendations makes it easier, but we are happy to help in whatever stage you are in!

Steps of a Photo Restoration

We see a lot of vintage photos here at Panopticon Imaging. They range from wedding portraits to family photos throughout the years to military portraits, the list goes on!  Here are the steps we go through for a photo restoration: STEP 1: Bring in your old photograph to the office. We will review the image with you & give you an estimate of how much & how long it will be to digitally restore. We DO NOT restore the original photograph. We scan it and digitally correct the image through Photoshop.

STEP 2: We scan your image. Using our high resolution Epson scanner, we create a digital copy from the original photograph.

STEP 3: We make adjustments in Photoshop. Here we fix cracks & damage to the image. This takes time and each photograph is different, it can take as little as 5 minutes or as much as 3 hours. We also adjust the contrast of the image, making faces lighter or certain areas darker. We can adjust the tone and make it black & white, sepia, or brown tone. The sepia is our most popular option, it makes the image still feel like an old photograph.

STEP 4: Time to print! We use all archival inks and papers here. This means your new print will last as long as it is treated properly (keeping it away from moisture & direct sunlight). When we meet with you we will tell you the sizes we recommend printing. Most vintage photographs are small to start with so they look the best staying in the 5x7 to 8x10 size.

These were the adjustments made to this image:

Whatever happened to your photograph, we are happy to help bring it back to life! Stop by the office or give us a call at 781-740-1300.

Artist Spotlight: Fern Nesson

Fern Nesson is a fine art photographer living in Cambridge, MA. She practiced as a lawyer for twenty years and taught history at the Cambridge School of Weston and, for the past ten years, she was the College Advisor at the Commonwealth School. Fern is currently in her first year of the MFA program at Maine Media College. Her abstract work is rooted in the elegance of light and line and is currently on display in our gallery until May 14, 2016.

  • You have a background in law, how did you transition into the art world?

FN: I have taken a long journey through many, varied careers – lawyer, American historian, fiction and non-fiction writer, history, math and law teacher, college counselor -- but the spine of photography has run throughout my life. My father gave me my first camera when I was 8 and he taught me to develop my photos in the darkroom not long after. Since then, I have been engaged in looking at the world through a camera.

Until recently, photography was my hobby. I knew several great photographers (my father included) and followed their work with interest. About ten years ago, I interviewed my father and we published a book of his work. I have also collected photographs for many years. I am proud to own photographs by Michael Kenna, Ansel Adams and Bruce Cratsley, among others.

Several years ago, I decided to pursue my own photography more seriously. My initial goal was to learn to take better photos. I began by reviewing my past work and publishing several books of my photographs. Then I took a workshop in photography at the Penland School in North Carolina. Finally, last year, I quit my counseling job to do photography full-time.

It’s taken me a long time to accept the challenge of pursuing life as an artist but I am so thrilled to be doing it! Photography provides, as always, a wonderful way to experience the world and the improvement in the quality of my work as a result of studying and practicing it full-time is immensely rewarding.

  • You are currently attending the low residency masters program at Maine Media, tell us a little bit about the program. How has your work changed since starting your studies there?

FN: For my first semester, I am completing synergistic studio and academic projects, both entitled “An Exploration of Seeing.” Since November, I have taken over 20,000 (!) photographs, read a dozen of the great books about “seeing ” and written three lengthy papers describing the evolution of my own artistic vision. As an intellectual and artistic experience, a Maine Media education can’t be beat!

"Light Lines 3"

  • Your abstractions of light and shadow show a playful & insightful side to subjects we see everyday. How do you choose what you point your camera at?

FN: Light is the theme in all of my work. I don’t shoot objects for themselves; I shoot their interaction with light: are they illumined from within? Are they transparent? Are they reflective? Are they suffused with light? Do they glow? Are they in shadow? Do they sparkle? My subjects are quite varied but it’s all about the light.

"Morning Light 5"

  • What inspires you as an artist?

FN: I am drawn to elegance. In choosing a subject or a scene, I seek elegance in pattern, line, color and shape. I prefer the intricate, small detail, over the panorama. My photographs are abstract but not in the sense of removing detail; just the opposite. I focus on an element and I abstract it through the use of an unusual perspective or point of view.

"Light Lines 5"

  • Your current exhibition in our gallery space is a selection of images from various portfolios. How do you feel the individual pieces interact with one another as a whole?

FN: The photographs in my show, “The Light Dances,” are selected from three different series, which I shot in 2015-6. Although they are of radically different subjects – trees at night, a Calder stabile, and the curtains in my bedroom – they have certain underlying and essential characteristics in common.

First, they are each about light: light as it illumines and ennobles a dark object, light as it enhances a sculpture by throwing off shadows, light as it sparkles and brightens a cold winter landscape.

Second they are multiples. Varying the point of view on a single object takes advantage of all angles of the object and allows maximum concentration upon its interaction with light. The multiplicity of views points up what is so great about our existence: we all see things differently from each other and it is that very diversity that makes art and life so interesting.

Third, they use the power of black. Light as a subject shows up so beautifully when it is contrasted with black. Color can seem sometimes to be cheating; it can make even a dull picture interesting but black is a challenge. If you use it well, you get drama; if you use it badly, you get nothing.
