I am trying to find out how to crop a fixed size image

Question

I have 13 scans of various images! pages from charts. the water tide flow and direction vary throughout the day

I need to crop a small part of all 13 original images to the same size for the same area on each image. (just as if it was a printed paper image cut out ) Note all original images scans are saved at 300dpi. I am trying to keep all the 13 cropped images at the same size & scale and area. They are Tidal charts Maps/charts with tide flow marked on them at various times of the day. I just need this local part of the original chart. I can keep them in proportion but not control the size of the area 30X40mm approx

I am lining up on a graphic point on each of the charts and dragging the crop box in proportion out but I don't seem to have any control over the total area size crop. I am using CS5 is there a way to do this

I would like to have the crop area the same size on all 13 cropped images Is there a way to do this with CS5 any help would be welcome

Thanks

Hi @daisyw11459631

Here's a second way to crop that may work better for you in this case:

Use the rectangular Marquee tool.
In the options bar, set the size to Fixed, then set the Width to 30mm and the Height to 40mm. Be sure to type mm or it may revert to pixels. Double-check.
Drag the fixed-size selection to where you want it. If you need to adjust it, use a selection tool (not the Move tool).
When ready, go to Image > Crop

When finished with all images, reset the Rectangular Marquee tool.

Do you have images at exactly same dimensions? If yes and you want exactly same part of image to cut then you can automate process using Photoshop action and ensure that you are cropping always exactly same part regarding X and Y axis.
