Iphone SE camera compared to equivalent Megapixel camera

I almost have a digital camera every where I go, but it really necessary? Are phone cameras getting good enough to replace standard point and shoot cameras? My comparison includes a Canon GX9. This is an older camera but it was the Cadillac of point and shoot cameras when it was first released. 

The Gx9 sports a 7-44 zoom lens with a maximum aperture of 2.8. It’s capable of shooting raw files. Best of all, the megapixel count is identical to the Iphone SE. Both are 12 megapixels. The Iphone SE has the same camera as the Iphone  6s. I prefer the smaller Iphone SE because it fits in a pocket better.

Images taken with the iphone were shot at ISO 25 at f 2.2. The Gx9 was set at ISO 100 at f/4. Shutter speeds were selected by the cameras and varied slightly but were high shutter speeds.

I shot similar photos with each camera, As the reader I want you to guess which is which. All files were captured as JPG’s with no modification. Click on the images to enlarge them.

Of course there are limitations when using a phone camera. They will not function as well in lower light and you don’t have zoom capability on many phones. However point and shoot cameras are also limited in low light. The GX9 can probably outdo the Iphone SE because of its raw file capability which allows more leeway in post processing. Of course the newest Iphone 7 also has raw file capability.

Lets see if you guessed right:

images A,F,Q,and X are from the Iphone SE.

Converting a camera to infrared

Last year I had a Fuji s3 converted to infrared.  https://www.lifepixel.com/ is the site that I visited and decided to utilize their services. I paid $275 for the conversion. Turn around was reasonably quick. It took about 10 days. There are a number of filter options available for conversion, If I remember correctly I went with a standard filter. I probably wouldn’t recommend using the Fuji S3 for conversion because its limited in doing a color balance once converted. The Fuji S2 cannot be converted due to the way the sensor is designed. You cannot use the original raw files to get the color effects wanted, unless you convert them to DNG files. Then by using Adobe’s DNG profile editor you can establish a profile for the Fuji camera and utilize the profile in camera raw. Results are good but the DNG file is not as large as the original raw file so you will be limited on how large you could print an image. The DNG files are around 17 mb when opened in Photoshop, Below are some sample photos taken this year.

In general my best results were on days with cumulus clouds and locations that included water. Water is cool and doesn’t reflect much infrared. Therefore it appears darker in the photos. Chlorophyll reflects a lot of infrared so trees and grass will appear light in black and white infrared photos and will appear in false colors when shooting images in color. Colors can be manipulated by adjusting hue and saturation. Infrared photos really need to include something which reflects infrared or the images will be very bland. You can include people in the photos but there colors will not be natural.
