If you are unsure about image use, then please contact me for any 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 Wide Web. Should you require any special arrangements for image use then please contact me to discuss 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 have it verified from a different source.


INFORMATION:

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 continuous-tone images 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 24 (8 bits 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 the 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 color 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 you intend to use.


Updates: There 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 well 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.

Even if you do not wish to purchase any photographs I hope that you will continue to view my site and enjoy the images it contains.

Many thanks for taking an interest in viewing my images.
