Hi [USER=132708]@Vicky001[/USER]
It would be a whole lot easier if you could share the TiFF file.
I did not see anything in your settings that looks like an obvious issue.
There are a number of factors that come in to play in TIFF size
Here is an initial rough calculation you can do on your own to see if the file is in the ballpark
First, multiple the image width in pixels by the image height in pixels
Then multiply by the number of color channels ( 3 for RGB, 4 for CMYK, or more if you have embedded channels in PS)
If you are saving in 16 bits vs 8 bits multiple by another factor of 2
The above gives you the non compressed size of the image file for a single Layer.
Then you add the metadata. If you include the raw file it will be quite a bit larger yet most metadata does not add that much in size
If you are saving a TIFF file that includes more pixel Layers, then that is about the same as adding more color channels (see calculations above)
In you prior images it had indications the image was 6886 x 4886 and was save as RGB 8 bit and then adding the raw image data
Without raw image data that would already be 100MB in size then you add the raw data.
The raw data size you indicated was 25.1 MB. That could not be done unless if was a compressed version of the raw file and not clear to me that when saving that as metadata that it would only use the 25.1 MB or would be a larger amount. You could turn off saving all metadata to determine how much smaller the image size will get. If an 8 bit RGB image TIFF that is single Layer with no compressions and no metadata for the example image size I inferred from you images above, then something else is going on and would require a closer examination of the file itself to determine what is going on.
So 192 MB sounds a bit high for TIFF with the assumptions I have stated.
Maybe another forum member can spot something I overlooked yet pretty sure for me to help more, I would need to see the TIFF file via a file sharing service.
Hope this helps
