All rights reserved. If you are unsure about image use,
then please contact me
information, help or advice on any of my images.
Image use: Unless by prior agreement, all
images are supplied for single use only and should not be
used in any other publication, these conditions also apply
to any image(s) used on the World
you require any special arrangements for image use then please
any requirements to suit your needs. In the case
of web publishing please inform me of the URL link to the
relevant Web page.
Image price: Images
are supplied at the agreed price on the quotation you receive,
price is per image and are normally sent to you by e-mail or if requested they can be written to a USB stick or CD and posted to you (p&p extra).
If you request the email option then
make sure that your mailbox is able to receive large image
attachments and does not reach its intake limit.
Disclaimer: Once payment is received and cleared
the image(s) will be sent to you by whichever option you request
on the order form, however, whether by e-mail attachment or post, I will
not be held responsible in any way for any delays howsoever caused
or for any missed datelines.
I have made every effort to ensure that
the information contained on this website on all of the subjects
I have photographed is as accurate as possible. However,
I cannot be held responsible for any errors, omissions or inaccuracies. I have
merely included information of interest to share with other aircraft enthusiasts,
anyone interested in Kefalonia and Ithaca or any of the subjects I have covered
and not for profit making. Anyone using this information should
it verified from
a different source.
File sizes and resolution: File size and
resolution is variable depending on the finished size of
the intended image and whether the image is to be used for
photographs, printing or web publishing. Unless otherwise
requested all images are saved as RGB 300dpi jpg files at the maximum quality option, suitable for e-mail transfer. Should
you require images saved in a different format than JPG
then please specify on
the order form your requirements, (e.g.
TIFF, PNG, etc.). These are the most common image file formats, the most important for general purposes today. These other file formats produce larger file sizes and are therefore not suitable for transfer via email and would have to be posted to you on a CD or USB stick..
JPEG/JPG (Joint Photographic Experts Group): This
format is commonly used to display photographs and other
in hypertext markup language (HTML) documents over the World
Wide Web and other online services. It is capable of displaying millions of colours at once, without the need for dithering, allowing for the complex blend of hues that occur in photographic images. Unlike GIF format, JPG
retains all color information in an RGB image but compresses
file size greatly by selectively discarding data. A JPG image is
automatically decompressed when opened. JPGs use a complex compression algorithm, which can be applied on a sliding scale. Compression is achieved by forgetting certain details about the image, which the JPG will then try to fill in later when it is being displayed. Lower level of compression
results in better image quality.
In most cases, the maximum quality option produces a result indistinguishable from the original. However JPG files should not be repeatedley edited and then re-saved again as image quality will suffer every time you re-save the file. The JPEG format is likely to be replaced at some point in the future by the updated JPEG2000 format which offers loss-less compression.
TIFF (Tagged Image File Format): is considered the standard photographic file format, because it is a highly flexible format that uses a loss-less compression algorithm, so there's no image degradation during compression. This ability to store image information in a loss-less format makes a TIFF file very useful for archiving images. Unlike a JPEG, a TIFF file may be edited and re-saved without losing any image quality. The downside is that TIFF files can be very large even if saved with LZW or ZIP compression. TIFF is the most versatile file format, except that web pages don't show TIFF files.
PNG (Portable Network Graphics): can replace GIF today (web browsers show both), and PNG also offers many options of TIFF too (indexed or RGB, 1 to 48-bits, etc). PNG was invented more recently than the others, designed to bypass possible LZW compression patent issues with GIF, and since it was more modern, it offers other options too (RGB color modes, 16 bits, etc). One additional feature of PNG is transparency for 24 bit RGB images. Normally PNG files are a little smaller than LZW compression in TIFF or GIF (all of these use loss-less compression, of different types), but PNG is perhaps slightly slower to read or write. Less used than TIFF or JPG, but PNG is another good choice for loss-less quality work.
File formats/color: RGB images use three
colors, (red, green, blue) or channels, to reproduce colors
on-screen. The three channels translate to
x 3 channels)
bits of color information per pixel. With 24-bit images, up to
16.7 million colors can be reproduced. The RGB model
is used by computer monitors to display colors on-screen. Although
RGB is a standard color model, the exact range of colors represented
can vary, depending on the application or display
device. Also all images on this site are low resolution, therefore
the high resolution images you receive may not exactly match
color rendition you see on your screen.
For printing: RGB files have to be converted
to CMYK (cyan, magenta, yellow, black) which are the process
inks used in the printing process. In
CMYK mode, each pixel is assigned
a percentage value for each of the process inks. The lightest
(highlight) colors are assigned small percentages of process
ink colors, the darker (shadow) colors higher percentages. For
example, a bright red might contain 4% cyan, 99% magenta, 100%
yellow, and 1% black. In CMYK images, pure white is generated
when all four components have values of 0%.
Converting an RGB image into CMYK: creates a color
separation. If you start with an RGB image, it's best to edit
first in RGB and then convert to CMYK at the end of your process.
Although CMYK is a standard color model, the exact range
of colors represented can vary, depending on the press and printing
conditions, e.g. type of ink, paper stock, type of printing press,
etc. (this can also vary from printer to printer). The colors
will also change between the RGB to CMYK conversion it is therefore
advisable to leave any conversion to the printing company that
will be ongoing updates to all sections in the future, images
will be added and changed so please revisit often as images that
are not currently available may very
be in the future.
Commissions/digital retouching: I am also available
for some commissions and digital retouching so please contact me to discuss any particular requirements
you may have, I will only be to pleased to help if I can in any way.
you do not wish to purchase any photographs I hope that you will
continue to view my
the images it contains.
Many thanks for taking an interest in viewing my images.
