While initially the photo’s look incredibly similar this is not the case. With the low end phone camera the textures of the objects are not made out as crisp compared to the high-end DSLR. The best example of this can be seen in the champagne bottle. With the low end phone camera you can’t make out the grey texture on the top of the bottle while with the high-end DSLR its pretty obvious. The lighting with the high-end DSLR is also picked up much less to that of the low end.
There are many things that effect of scanned resolution on image size. In many cases such as the magazine scan, drawing, and object, the resolution allows the object to be crisp and clear without any major limitations. However with the original photo, in this case a digital one of my dog, the resolution will only be as good as that original photo. It may look a little crisper due to the lighting of the scanner, but as stated earlier the resolution will only be as good as that original photo.
When setting up the dimensions I knew i wanted to make a landscape so I went with dimensions of 7 in by 5 in. I also did it this way as if I wanted to print it it would be correct dimensions for a traditional digital photo. I also set the resolution to 150 as thats a good median to use in an image for both web and as a hardcopy photo.
