5x macro duplicated, flipped, stitched.
I see a halloween goblin and an otter looking into the camera. In order to help you find them I made some subtle changes to the second photo :-D :-D
Enjoy :)

I find symmetrical images to be fascinating because we "see" things based upon the uniqueness of each human mind. The complex nature of the mind is something to ponder. I appreciate your comment :thumbup:

Akin to ink spots, your images are interesting and cause me to spend more time viewing.
I would love to ponder the mind but, it seems that I have lost mine:|

Interesting.
When you say 5X macro, do you mean 5:1? Like with a bellows or multiplier?
Curious...

I used Canon's dedicated macro lens MP-E 65 and set the lens at the 5x mark. This is 5 times larger then life size (1:1). The camera Canon Xsi does not have a full frame sensor; therefore there is a multiplier effect of 1.5. 1.5 times 5x = 7.5x . :-)

This is not quite right. The Canon MP-E 65 at 5x produces 5:1 magnification, no matter the sensor size. Magnification is the relationship between the subject original size compared to the captured size on a sensor. It makes no difference if the sensor is small or large.

You are correct. The optical image is the same size on both a full frame and a cropped sensor. Let us assume that the number of mega pixels is identical within a square millimeter on each sensor.
The cropped sensor captures less of the peripheral area of the optical image. If the cropped sensor photo were shown on a monitor it would have a large empty border on all 4 sides and the objects in the center of the photo would be the same size as a full frame photo. So why is there no border visible on the monitor? It is "stretched" by the camera /computer/monitor to fill the screen. No additional information is added to the cropped sensor photo. This is why bird photographers like cropped sensor because it gives them more 'apparent' reach.
I am not an expert on this topic therefore, I will gladly receive any explanation that better describes this phenomena of "stretching" the image to fill the monitor. :D

I just had an interesting thought. I do not recommend that anyone should try this - What if a full frame camera with the MP-E 65 macro lens took a photo at the 1x setting. Then if black electrical tape were placed around the 4 borders of the sensor so that only the cropped sensor size of the full frame sensor were exposed to the optical image and if a photo were taken of the same object with same 1x setting, what would we see on the monitor? I assume we would see a 1x photo with a wide black border on all 4 sides. If the first photo were compared to the border photo, everything within the central area of the photos would be the same size. If post processing were used to cut off the border, I assume that the computer /monitor would expand the cropped image in order to fill the screen. This expansion would cause the objects in the photo to appear larger then the two images mentioned earlier. The image would be larger than 1x, perhaps 1.5x. However, I could be wrong. :-)

Nikon full frame cameras know when an FX lens is used (projects for a full frame sensor), and when a DX lens is used (projects for an APS-C size sensor). With a DX lens, the camera will use only the center 16x24mm of the 24x36mm sensor. The image always fills the camera LCD viewer.

Thanks for the Nikon information :thumbup:
I came across a video that uses a zoom lens set at 100mm and first a photo is taken with a full frame and then using the same lens with the same settings, a cropped sensor body is used. The 2 photos are compared and the cropped body photo is larger. I assume that this would be true for the MP-E65 Macro lens. The comparison is done within the first minute of this 8 minute video. http://petapixel.com/2014/03/28/concise-explanation-crop-factor-affects-focal-length-aperture/

Do not confuse image magnification (on sensor) with projected or printed final image size. The same image printed onto 4x5 paper and an 8x10 paper show the same magnification, but not the same image size.
