USB microscopes
Hi everyone, I was thinking of buying a USB microscope just to see what I could do with it. You understand what I am talking about, right? Something to get an image onto my computer screen and then be able to capture that image, I guess as a JPEG or a TIFF. I am not looking at imaging anything in pa...

Hi Rik (and of course anyone else), Your explanation of pixels with my 3.99 mm iPhone 8 Plus focal-length camera really intrigued me. It got me to wondering if I could determine the actual size of an object from its image, since I do have information on the pixel values. I was recently at a botanica...

Re: Its comparing apples to oranges
Both of the iPhone 8+ cameras are 12MP cameras, and both share a common die size, however the wide camera has has a larger pixel pitch ( 1 vs ~1.22 um ) . So the ratio will not be 2:1. It should be something like 2 * ( 1 / 1.22 ) = 1.64:1 which is certainly close enough to your observed value. -- B...

Hi George and anyone else, Now I understand my confusion on the focal-length issue. I can formulate the question, but I don't know the answer. The 2X optical zoom should produce an image twice as large as does the 1X optical zoom. To test this, I used my iPhone 8 Plus to take a picture of my house, ...

FWIW, I was looking at some images in my Lightroom, knowing I took both 1X and 2X pix with a iPhone XS Max. They all show up as 3024 x 4032, but one has a Focal Length of 6mm and the other as 4.25mm. That means it is really Optical, not digital 2X. Should be the same for you iPhone 8 Plus. George H...

Stanley, Thanks for alerting me to the existence of Hunter Research & Technology's Theodolite app. I took a look at it and decided it would be well worth the $6 price for things I do. I also like their other apps, such as Professional Compass, professional altimeter, Nav Camera, and Weather. I ende...

Hi everyone, No one answered by question regarding digital versus optical zoom, and of course none of you nice people were obligated to respond. So I continued to further investigate this issue. I was not finding definitive answers, so finally I contacted Hunter Research & Technology (let’s call it ...

Is the 2X zoom on an iPhone 8 Plus digital or optical zoom
Hi everyone,
I recently took some macro shots using my iPhone 8 Plus at 2X zoom. I thought that 2X on the iPhone 8 Plus was optical zoom.
But the EXIF information on my photographs called my 2X “DigitalZoomRatio.” So, please, is the 2X zoom on my camera optical or digital?
Thank you.
Stanley
