Copyright

Its a fairly easy concept to explain but not easy for many people to accept. Here we make some sense of it for you

Our Policy

"To comply with Copyright Law, we will not knowingly scan, copy or work on a photo that has been taken by a
professional photographer within the last 100 years without the permission of the photographer or their estate"


To save yourself disappointment, these are the things we look for before proceeding with your job

Any indication of the date or age of the photograph. If it is old enough we can ignore the other criteria

Professionally taken photos usually have copyright stamps, marks or a business name on the back.

Mounted photographs could be professional. Look for the photographer's name or mark on the mount

Photographs may look professional in the way they are taken, i.e. " In a studio type environment like
Graduation Photos". Even without a mark in many instances we decline obvious Studio Photographs


Copyright Law is stringent and the penalties very high. We will however only apply the above criteria.
We are building a Photographers database to make our life a little easier. In the mean time if you
want a School photograph repaired you will need to get the photographer's written permission first



The Copyright Concept

Copyright really means "Ownership of the created image, design, words or ideas"

Here we are talking about "Who owns the Image", not "Who owns the photograph"

You may pay good money for the photographs, but you do not own the Copyright.

Wedding Photos are a good example. Pay big bucks but the copyright is not yours



Who Owns it?

Copyright belongs automatically to the photographer or their employer if part of their job.

It remains their property unless specifically sold, gifted or becomes redundant with time.



How long does it last?

In the UK copyright belongs to the photographer & their estate for 50 years after their death

A professional photographer doesn't give up copyright easily. That event is normally in writing

Print Formats & Cropping

A common problem when getting photographic prints is unexpected & unwanted cropping of the image.


Type 1
All photo printing services have a small automatic cropping around the border of the negative or digital
image to give a clean edge to the final print (2% to 3%). Not usually a problem as it rarely cuts into the
main subject but if the object is too close to the edge of the picture or negative it can be cropped a little

Photo Doctor can cure this. Just clearly state "No Cropping" in Special Instructions on the order form.

Type 2
This happens when the print proportions are different than the proportions (Ratio of the height to width)
of the negative or digital image. A 35mm negative proportions fit a 6"x 4" print but a 7"x 5" print will be
cropped at the sides. Again this is not usually a problem but on occasions part of the subject can be
cropped. Today's automatic processing means that this is not always picked up.

This will not occur with Photo Doctor as all our work is by hand and continually monitored. If you have
selected a print size that would result in unacceptable cropping we will inform you and offer solutions.

Enlarging and Print Sizes

These are notes on enlargements & the limitations. Different factors apply to the different source media.
We cover information on enlarging from Prints (Flat media), Negatives, Transparencies & Digital Photos


Enlarging from Prints

You cannot enlarge from a print without some loss of quality. The more you enlarge, the greater
the loss in sharpness, definition and colour saturation.

We use our skills to minimise those losses. Photo Doctor can safely double the original print
size without noticeable deterioration but beyond this depends very much on the original photo's sharpness and definition.

Our standard service 7"x 5" print assumes that the original photo is of a reasonable size (4"x 3"
or bigger). If the original picture is very small, like a passport photo, we will try and achieve the
7"x 5" print of decent quality but if the original is not clear or sharp we may not get there. If we
have difficulties we will contact you with options. (i.e. two 6"x 4" prints instead)

Larger prints will depend on the original print size, the sharpness and definition of the image.

Enlarging from Negatives & Slides

A fine razor sharp 35mm negative or slide could be enlarged up to about A3 size satisfactorily
but the maximum "quality" print size would depend on the sharpness and definition of the photo.
9"x 6" prints are fairly safe from the average photo and Photo Doctor will generally achieve this.

Negs and slides bigger than 35mm can be enlarged more as long as they have some definition.

We will apply our skills to maximise the enlargement capability of your photo. Should there be
difficulties in achieving your requested print size we will contact you with options and solutions.


Enlargements from Digital Camera Photos

Digital photographs can be taken at different resolutions that are usually referred to in terms of
Megapixels (1 Megapixel = 1 million pixels). This has a direct bearing on the size of prints that
can be printed out at reasonable quality.

Below is a table giving realistic print sizes for each Megapixel value.
These are split between sizes for "Normal" and "High" quality prints.

Resolutions
Megapixels
Quality Noticeable
Crop
Normal High
1 6"x 4"
Nil on 6"x 4"
2 8"x 6" 6"x 4" on 6"x 4"
3 10"x 8" 7"x 5" both Slightly
5 12"x 10" 10"x 8" both Slightly
6 15"x 10" 12"x 10" on 15"x 10"
8 18"x 12"+ 15"x 10" on 15"x 10"
& 18"x 12"


We will do larger prints if you request but you will be advised that there may be
a drop in quality. Photo Doctor will work to give you the best quality possible.

Digital Services Specifications

These specs cover the resolutions for scanning slides & scanning negatives, the approximate file sizes and
recommended maximum printout sizes for the different scanning levels . The 2nd table lists the file formats
we can work with and convert

Scanning
Digital archiving (photo archiving) valuable memories

Any flat media, paper or photographs up to A4 size

35mm and APS film (Scanning Negatives & Slides)
in film strips or slide mounts

These would normally be saved as Tiff files and written to CD but they can be saved as
High Quality JPGs or any suitable file format you wish . Enter your preference in
" Special Instructions " on the order form . Note - most other formats create much larger file
sizes when saved so there would be fewer pictures on the CD. Photo archiving does not
include hand adjustment of photographs or the removal of excessive dust and scratches.

They are digital copies of photos as supplied. Hand assessment and adjustment by
quotation. For more information on what we do - Read Notes on Scanning.

Although we can do photo restoration work on larger formats, we cannot do bulk digital archiving
work on medium & large format film or plates or flat media above A4. We do have plans however

File Conversion

Conversion to other formats and modes often causes a drop in quality or fewer colours ( i.e. from
RGB to CMYK, RGB to Indexed Color or from TIFF to JPEG). We minimise these losses to give
you a picture as close to the original as possible, within quoted prices. Should conversion cause
an unacceptable drop in quality we will advise you of alternative options.


Color Modes

RGB CMYK Indexed Color Lab Color Grayscale

Duotone & Multi Channel modes are specialist modes for professional printing & not handled here
Graphic File Formats

We can convert to and from all these common Raster graphic formats
JPG (JPEG) TIF (TIFF) BMP RAW GIF PDF
and many of the less common ones including
BMP (OS/2) EPS MAC PICT TGA
CAL EPS (DCS 1.0) PCT PNG VDA
CPT EPS (DCS 2.0) PCX PSD VST
CPT (PP 6) FPX PDD PXR WBN
DIB ICB PDF RLE WBNP
DCS JPE PDP SCT WI
Formats & Modes limited to 256 colours or less are underlined

We can work with many more file types, Vector & Raster, and convert to any
of the above formats within the inherent format limitations of color and quality.

Please note that a file that is security encoded or a picture that is watermarked
is copyright protected and we cannot work on it without the authors permission

Notes on Scanning & Digital Archiving

We have 35mm facilities for scanning negatives in film strips and scanning slides in strips and mounts.
APS
can be handled in strip form only. We scan to different resolutions, as you require, up to 2820dpi.

This suits the majority of normal applications, although with recent developments resolutions up to 4000dpi are
affordably possible. However, despite counter arguments, any resolutions above around 3200dpi are starting to
stretch beyond the limits of film grain size.

Our digital archiving service includes scanning slides, negatives & prints to the required resolution & writing
to CD. Negatives are scanned and the image is converted into a positive image. All scans are automatically
adjusted for exposure and there is a basic cleanup of minor dust, which is always present.

However our photo archiving service is for scanning to CD and does not include cleaning of dirty & damaged
material or hand adjustment to correct for color, contrast or sharpness. The scans are digital copies of the
pictures as supplied. You will be advised should extra work be required for dirty or damaged negatives &
slides. Any extra hand assessment and adjustment is be subject to individual quotation.
