Images stored on computer show very small

[sybrenlyts]

Yesterday I tried out storing my images on the computer. Reviewing them on the same computer, a very small picture was seen. Fortunately, the same picture looked normal size on an alternative computer.

 

Storage time increased from image to image, BYE claiming to be active on them. What kind of activity should it do, and could I switch that off?

Not sure about the small thingy, I'm not sure what you mean <_>

 

Can you please provide more information on time increases from image to image.  Are you taking BULB images, if yes how long?  Are you taking TV Images, etc.

Using a rather standard Image Processing App such as IrfanView, examine several of your Images (both "small" and "large" and "fast" and "slow") for their Pixel Dimensions and File Sizes and Exposure details.  Post those details as a little table, and it might help explain what you are seeing and/or what might be causing it.

The images stored to computer are multiMB, but in IrfanView show at only 100 by 120 or so.

Same images, copied on USB-stick, taken to another computer, show at normal size.

 

I do not have exact data on extra time for downloading, the long pauses were for bulb exposures at 30 sec each. The former 120 sec images took a reasonable 5 or 7 sec to download.

Myself, I have no idea at all what there is to process on a downloaded image.

In BackyardEOS you mean?

 

BackyardEOS does NOT process image data at all.  The image data inside your raw .cr2 file is as-is coming out of the camera.

 

But BackyardEOS does do stuff with it post download... 

 

1) it reads the raw data to display the image,

2) it computes the histogram,

3) it reads the exif data to get the sensor temperature,

4) it adds exif data such as the target name, frame type, ambient temperature, etc...,

5) it renames the image file

6) it moves the final image from the TEMP folder to your selected download folder.

 

These tasks takes time beyond the 6 to 8 seconds it physically takes to download the image and some of them are CPU intensive.

 

Hope this helps.

Since the same picture looked normal size on a different computer, you might want to compare the screen resolutions on the two computers. If the one showing the small pictures is less than the maximum resolution its display is capable of, I suggest changing the resolution to its maximum value. You can determine the resolution by right-clicking with your mouse on the desktop where there is no icon, and selecting "properties" or "display resolution" or something like that, depending on which version of Windows you are running.

 

Hope this helps.
