Photo Library Image preparation is essential if you want to make sure your images are accepted for sale.
I remember when I first wanted to sell my work through an image library and I was amazed at all the rules concerning the quality of the images from resolution and sizing to colour space and file saving.
However, when you consider that people who want to buy images will want the highest quality possible, then you can understand why a photo library only wants to promote the best images possible.
Below are some Photoshop tips and general advice on how to polish and prepare your images for submission.
Remember, photoshop can help make sure your images meet the requirements of these libraries but always read the specifications of the photo library you are submitting your work to, as often they may have their own special requirements that may differ.
Colour casts are caused when the wrong white balance setting has been used when taking the picture or that the lighting conditions were difficult and the setting was unable to remove any cast completely.
By using the Photoshop eyedropper in the raw converter window, colour casts can be adjusted to produce a much better quality image.
Often images can appear a little flat and lack a full range of tones. This is simple to adjust using levels.
Make sure there are no specks of dust or hairs on your image that may have been caused by dirt on the camera sensor. Any marks should be removed before submitting to a photo library.
There are two Photoshop tools that can help you remove any blemishes:
The Clone Stamp Tool - this copies pixels from one area of your picture and covers the blemish.
The healing tool - This is a similar tool but is able to blend the pixels better especially in smooth clear areas such as sky.
To use these tools see the page about removing blemishes.
Once you have removed the mark, zoom in on the area at 100% magnification to make sure that all signs of the blemish have been removed.
Photo libraries require images that can be printed to a high quality at large sizes. Because of cropping and ambiguity between cameras regarding mega pixels, the industry uses megabytes when they talk about the size of an image.
To check what size your final image is:
Your image library may require you to submit a 48mb file to them (check that your photo library will accept interpolation). So you must interpolate (adds pixels to your image) your image to reach this file size. To do this:
Check which file formats your photo library prefers to receive images in.
JPEG - This is really only suitable for saving RAW file to because there is a slight drop in quality. However you will be able to save more files onto a CD.
To save with this format:
TIFF - This is a better quality file format but is a much larger file to store. There is a LZW compression format that if acceptable to the image library can be used to reduce the file size.
To save with this format:
Your images should now be ready for submission to your chosen photo library.
