How do I get realistic distance representation using GIMP?

How do I get realistic distance representation using GIMP?
=============================================

Thanks for your input to my postings. I am using GIMP 2.8. I am not an expert.

I have two images (image1 & image 2). I have same object in image 1 & image 2, but the object is displaced between images. I used GIMP to overlay both the images to figure out the displaced distance. Here is what I did.

I created the 1st image from clipboard, I open a new layer and placed the 2nd object. I adjusted the opacity to provide transparency between image 1 & image 2 . I find image 2 is layered on top of image 1, but the displaced distance is not representing realistically on layered image. I tried with zoom. Images look odd.

How do I make the images to be sync to displaced distance?

I am attaching the layered image for review.

Thanks for sharing.

Thanks for chiming in.:) I tried to make png or jpg format for this posting. It did not work out. That was the reason, I posted in pdf. I welcome some suggestions.

I am not able to save as png or jpg format using GIMP. I tried to copy & paste the layered image as shown in pdf (before making to pdf) to paint. it copies only current layer from GIMP. I means it brings only single image.

Let me know, how to make png or jpg format of layered image of GIMP?

I will be glad to satisfy your request.

Thanks for helping.

Thanks for your Layer Masking tutorial. Good to learn some new stuff. It won't have happen without you.

If you review my separate images (base images), I am working with. Both are not on same zoom level. I mean that image 2 is a distant view with displacement.

What is the beast way to overlay these two images by preserving displacement?

The tutorial did not address this piece.
