1 Preparations Before Photographing

 

 

Log

If you select the check box labeled “with LOG.txt,” the function for attaching a log (comment statement) is enabled when you save an image. Writing information such as subject name, number, and objective magnification in a log may facilitate future confirmation.

You can write up to 100 characters to a log when saving an image to a card or server, or up to 32 characters when outputting to a printer.

Photographed data (including Nikon 80i/90i microscope data during photography) is also contained in a log.

•When you save an image in BMP format, the log is saved to a file named after the image, with the extension “txt” added.

•When you save an image in JPEG format, it is saved to a file named after the image with the extension “txt” added.

Further, it is embedded in the image file as Exif information.

•When you output an image directly to a printer, the log is printed as a comment.

NOTE: You can attach a log when saving an image even if you didn't select Log during initial settings. Select the Append check box for Log on the REC menu and enter a comment in the text box. Photographing information and your comments will be saved in text format when you save the image.

File Type

Set a file format, an image size, and a compression rate.

TYPE:

Select “JPEG” or “BMP” as the format in which you want to save a file.

SOURCE:

Select the source type based on photography mode. This setting applies

 

when freezing images, saving image files, or printing images directly. Use

 

this setting to ensure the image quality level for saved images. You can

 

also use this setting to avoid switching CCD modes when freezing images.

 

For 5M cameras, choose "s5M" or "s1.3M."

 

For 2M cameras, choose "s2M" or "s800*."

 

For setting guidelines, refer to "Source Setting Guidelines (Photography

 

mode)" on the next page. If you set the source to the highest resolution

 

("s5M" for 5M cameras or "s2M" for 2M cameras) and select "Auto change

 

CCD mode," the display mode will adjust automatically to match the

 

camera shutter speed. For further details, refer to "Auto change CCD

 

mode" at the end of this chapter.

SIZE:

Setting the size of saved images.

 

For 5M cameras, choose "2560*1920," "1280*960," or 640*480."

 

For 2M cameras, choose "1600*1200," 800*600," or "400*300."

 

If you set the source to "s800*" and the display mode to "800*5" while

 

using 2M cameras, the actual image size will differ from the designated

 

size. Images will be saved at 800*560 resolution if you select "800*600"

 

and at 400*280 for "400*300." This means portions of the image at the

 

top and bottom will be cropped out.

 

Saving images as "400*300" JPEGs will produce 400*296 images,

 

cropping out a small portion of the bottom.

 

When using either 2M or 5M cameras and saving images for display from

 

CF cards again, the image size is changed to 1280*960. With 5M cameras,

 

images will still be saved at 1280*960 resolution, even if the specified

 

image size is "2560*1920." Likewise, with 2M cameras, images will be

 

saved at 1280*960 resolution for a specified image size of "1600*1200."

 

Specifying an image size of "800*600" will result in 640*480 resolution.

JPEG Quality:

If you select JPEG for the file format, select a compression rate (picture

 

quality) here.
