Great app for iPhone, but is NOT a DSLR replacement

After reading a few of the comments, I had to stop what I was doing and write a review for the sake of those who do not understand digital cameras and photography in general. I am a professional photographer who has been shooting since 1975 and currently uses high-end digital DSLR gear. And my iPhone 65 Plus. : ) You know that saying… “the best camera is the one you have with you”? Well, my iPhone ends up being that one a high percentage of the time.
1. Cortex Camera IS a great app - if you are going to use the iPhone to shoot the image. It DOES outperform the native camera app and even some of the other better and more sophisticated camera app replacements due to its ability to manage the digital noise issue. In low light, Cortex Camera is my current go-to app and the statements made about it on the App Store are generally accurate, except for it being a DSLR replacement.
2. There is NO WAY this app is going to outperform a high-end DSLR and anyone who says it will is either inexperienced and doesn’t know better, or is misleading you. A high-end (full frame sensor) DSLR has a sensor chip that measures approx. 36mm x 24mm. It’s light gathering power and dynamic range is huge and will leave 100% of all smartphone cameras in the dust, regardless of the brand. Because of the dynamic range issue, high-end DSLR’s can literally see in the dark and I have yet to see any smartphone of any brand that can do that with current technology. Get the mm specs on the sensor in your smartphone and see what size it is. You will quickly see the difference. Case in point, my iPhone 6 Plus sensor is 7.62mm x 7.62mm. You cannot take a chip that small and expect it to match the DSLR’s capability. If any smartphone today could match the image quality of a professional DSLR, then pros would save the money and the weight and use smartphones instead of spending $10K-$15K for camera systems. So let’s put to rest the statements of “as good as a DSLR”. Folks, it ain’t gonna happen! OK… : )
3. But if you are content to use your smartphone to shoot an image in low light, then this is your app. It appears to be as good as it gets with the current apps out there.
