images of fired glazes may be obtained in one of two ways:
a photograph of the fired glaze
the fired glaze with a digital camera.
will only accept images with a '.jpg' file extensions.
If you have
taken a picture of a glaze with a digital camera then the file will
most likely be save in the JPG format.
If you are scanning
your glaze from a photograph then you should choose the JPG file
format option for saving the digital image.
a glaze for the purpose of eventually linking it to a Matrix recipe
file you should remember that what is needed is an image which will
convey as much information about the glaze as possible.
In order that
glaze picture files do not take up too much disc space they must
be reasonably small. When displayed on screen they may not be any
larger than a matchbox. A photograph of a pot will therefore not
give very much information about the glaze.
a photograph of a glaze get as close as possible to the surface
and try to arrange the lighting so that the surface texture is clearly
the Quality of Digital Image
is used it is sometimes necessary to adjust the digital image to
obtain the best match for the original glaze.
This is best
done by loading the image into software such as Photoshop
where you may alter the colour balances and contrast and can sharpen
the image. If you have taken a well lit image this may not be necessary.
the Digital Image Size
If you have
unlimited disc space you could use images with high resolutions
thus giving your glaze pictures great clarity and detail even when
they are enlarged in Matrix's glaze picture window. Unfortunately
most of us have computer systems that do not have the disc space
for storing hundreds of large picture files.
usually create JPG files of around 50 kilobytes. When these are
loaded into software such as Photoshop they are expanded to a full
900 kilobytes. The pixels dimensions of these images is around 640
wide by 480 high.
To reduce the
size of your digital glaze image (and thus the storage space needed
on disk) :
- load the
image into software such as Photoshop and
- adjust the
displayed image size down to around 50 kilobytes. The pixel dimensions
of a JPG image of this size is around 150 wide by 113 high.
- save your
image anywhere in your system making sure that you choose the
.JPG file extension. When saved to disk as a JPG file it's size
will be around 7 - 10 kilobytes. This sized image gives good detail
when displayed in Matrix.
- You do not
need to save the initial glaze picture in your Matrix folder.
When Matrix attaches an image to a recipe it will place a copy
of that image in the same folder as the recipe file.
