acquire an image. +For reflective scans (photos, magazines, etc.) select <i>full color range</i>. +XSane comes with some predefined media. With some luck you can use such +a predefined media, but in general you have to create your own media +definitions because each scanner model generates slightly different colors. +Especially for negatives you have to define a media for each negative type +because they all have a different color of the film mask. +<p> +When you change the selection then it may be necessary to +do a new preview scan to get correct colors in the preview window. +The small point left of the <i>Acquire Preview</i> button in the +preview window tells you if the preview is correct or not. +<p> +Set the color correction sliders to default before you do a preview scan. +With a correct media definition you should get a preview with more or +less natural colors. But you have to apply a color correction afterwards. +You can not expect that the results are ok without a fine correction of the +colors. You can start with an automatic correction but especially for +negatives it is good to do a manual fine correction before the final scan. +<p> +<br> +<a NAME="MEDIUMDEFINITION"></a><b>Create or edit a medium definition:</b> +<br> +You can create and store your own definitions for different source media. +<p> +In the <i>preferences</i> menu there is an item <i>edit medium definition</i>. +<br> +<br> +<img SRC="xsane-preferences.jpg" alt="medium-definition-menu"> +<br> +<br> +When you enable this item then the icon before the +slection menu of the medium gets a little slider on its right side: +<p> + +<img SRC="xsane-edit-medium.jpg" alt="edit-medium-definition"> + +<a NAME="MEDIUMDEFINITION"></a><b>Edit medium definition:</b> +<br> +<b>When this icon is visible then you can edit and create medium definitions. +Do not use this mode to scan images, xsane will not behave like you expect +when you try to scan images in this mode.</b> +<br> + +<ol> + +<li> +<img SRC="xsane-rgb-default.jpg" alt="rgb-default"> +To define a medium for color scan disable the <i>RGB default</i> button +then you have sliders for each color separately. +</li> + +<li> +<img SRC="xsane-negative.jpg" alt="neagtive"> +When you want to define a medium definition for a negative +then activate the <i>negative</i> button. +</li> + +<li> +Now do some preview scans from the medium you like to define. +Set the color correction sliders <i>brightness</i> +and <i>contrast</i> so that you cut almost all unused color levels. +Do not cut any used color levels. It is better to keep a little +safety distance to the used colors. You can do a color correction +later in the preview window to cut unused colors, but +when your medium definition cuts colors that are used in your images +then you are not able to get these colors back. +<br> +For negatives it is a good idea to select a part of the frame around the +image, but if possible do not select any holes. The frame around the image +defines the color of the film mask. In general the image does not contain +such a color but you can be sure that this mask defines one end of the used +color range. +</li> + +<li> +Set the <i>gamma</i> sliders so that you get natural colors. If you are unsure better +leave the gamma value close to 1.0, you can apply the gamma correction later. +</li> + +<li>To save the new definition or to rename, delete or reorder existing definitions: + +<ol type="a"> +<li>open the medium menu with a short click with the left mouse button.</li> +<li>Move the mouse pointer to the entry that you want to edit or where you +want to add the new entry.</li> +<li>Press and hold the right mouse button to open the context menu.</li> +<li>Select a function in the context menu: +<br> +<br> +<img SRC="xsane-medium-add.jpg" alt="add medium"> +<br> +<br> +<span style="font-size:14pt"> +Remark: The item <i>add medium definition</i> is only available in the context menu +when <i>edit medium definition</i> in the <i>preferneces</i> menu is enabled. +</span> +</li> +<li>When you save new media definitions then please use the manufacturer and +the type of the medium as name.</li> +</ol> +</li> + +<li> +Disable <i>edit medium definition</i> in the <i>preferences</i> menu. +</li> + +<li> +Test the newly created medium definition.
