Bob's iPhone Photography

I realized the other day that I haven't posted a diary of my iPhone photos for quite some time, mid 2013 was the last time. So here are some random images that I've taken since '13. If you'd like to see all of my favorite shots that I've taken with my iPhone you can see them at

This is a shot I got on my morning walk around school (I'm a teacher). We have lots of ivy growing up the walls around campus.

Bob's iPhone Photography - Lesson 5

Contrast and Saturation

This is the 5th diary in my iPhone Lessons series.  

The human eye is an incredible thing, it can detect a wide range of light. Your brain takes the light information that comes from your eye and interprets the light in ways no camera can duplicate. Most photographers have a goal of reproducing on a 2D piece of paper what they were looking at in 3D through their eyes. Unfortunately that's not an easy task.

Since photography was invented people have been tweaking their images in the dark room, and now on the computer, to get an image that best duplicates what they were looking at when they took the original picture. Most pictures we take come out a bit flat compared to what we were looking at in person. While there are many things you can do to adjust the image on the computer to better reflect what you saw, today I'm only going to go over Contrast and Saturation.

Contrast is the difference in brightness between the light and dark areas of your image. As I've said before, your image should have black in it somewhere and white. If it doesn't, then you need to adjust the contrast of your picture.

Saturation has to do with the vividness and the intensity of your picture.

On your iPhone if you simply use the Photos app's "Auto-Enhance" feature the app will adjust your contrast and saturation to what it thinks is the best setting. It does a pretty good job most of the time. When I need more control than the Photos app offers I usually use either PS Express or the iPhoto app. You can also upload your images to a site like Photobucket or Flickr, they offer online photo editing tools that do a pretty good job. Of course you can also transfer your images to your computer and use programs like Photoshop, Aperture or iPhoto as well.

Below the squiggle I've got before and after examples of pictures I've adjusted the contrast and/or saturation on. In some case the effect is subtle, in other cases more obvious. Basically you adjust the image until it looks good to you, trying to match what you were looking at when you took the picture.

I live in San Diego so it was really nice being able to drive up to Netroots Nation this year. I have friends in the Bay Area and I was looking forward to being able to get up there a few days early and visit with them.

The first day I stop for the night in Paso Robles and had dinner at Firestone Walker Brewery's Taproom restaurant. I already knew they made great beer and I was please to find out the food was incredible as well. The next day I drove up to Santa Cruz and met up with an old friend, we did some bar hoping then ended the day on his deck drinking wine with his wife (who I've known since I was 10) at their home in Scott's Valley.

The next day I drove over the hill to San Jose and checked in to the Marriott. Unfortunately my son managed to give me his cold just before I left so I spent Tuesday and Wednesday mostly in bed or at least taking it easy. On Thursday I did mange to get to a few sessions, standing in the back so I could go out into the hall and cough. I mostly hung out at the Netroots for the Troops booth, didn't have enough energy to do too much more than that.

By mid day on Friday I was feeling a lot better and was able to both help out with NFTT and get to some more sessions. Saturday went great and Sunday I felt so good I drove all the way home, I missed my kids and my bed so I pushed through instead of stopping in San Luis Obispo like I had originally planned.

Even when sick I still manged to take lots of pictures on my iPhone, about 550 for the week. So I'm sharing with you some of my favorite shots.

A few weeks back I started a new diary series here on DKos, Bob's iPhone Photography - Lessons. I still have a lot of topics to cover and will be doing that in the coming weeks. So I hope you enjoy these shots from NN13, if you have any questions about the pictures please feel free to ask.

Please Note: some of these pictures will be hard to see only 600 px wide. If you click on the photo you will be taken to a larger image.

Bob's iPhone Photography - Lesson 4

Reposted from Bob's Blog by bsegel

In my last lesson diary I talked about High Dynamic Range photography, this week I'm going to go over how to stitch your images together to get great panorama pictures.

Full sized image

Lets face it there are lots of times when what you want to take a picture of wont fit in the entire frame of your phone/camera. If you are using a single lens reflex camera you can simply swap out for a wider angle lens but you can't do that with your phone. Sure, there are add on lenses you can buy now for the iPhone but how many of you have those? Not many I'm sure.

Fortunately there are apps now that make stitching multiple pictures together easy.

Bob's iPhone Photography - Lesson 3

This week we are going to explore High Dynamic Range (HDR) photography.

Full size image

The photo above is actually two pictures put together.
In the first picture the camera app meters off the building and takes a picture that gives the building good light exposure. Then for the second image the camera meters off the sky and takes the image so that the sky has a good exposure.

Typically a HDR photo is made up of about 5 different exposures of the same image. One shot taken at what the light meter says is the correct exposure then two shots above and two shots below, usually about one stop difference between each exposure. I know, technical talk and right now some of you are going, "huh?" Don't worry, stick with me and it will become clearer.

When shooting with an iPhone taking 5 separate exposures of the same thing really isn't an option.

Bob's iPhone Photography - Lesson 2

by bsegel

Reposted from Bob's Blog by bsegel

In lesson 1 last week I introduced a few rules of photography that can help everyone take better pictures. The Rule of Thirds being what I feel to be the most important rule followed by understanding lighting as the second most important issue.

I also touched on framing your images for action, shooting in water, close up shots with your iPhone and converting your shots to black & white.

This week I want to talk about another composition trick I use, not always showing the whole image.

Bob's iPhone Photography - Lesson 1

Welcome to my new diary series, Bob's iPhone Photography. As a lot of you know I do a monthly diary where I highlight the photography by Pete Souza and his staff of White House photographers and then occasionally post diaries of my own work.

I have been a photographer for over 30 years now. I started shooting 35 mm and 2 1/4' negatives, processing them in my own dark room, then moved to digital about 8 years ago.

Back in August of 2011, after being challenged by the Mojo Friday crowd to post more pictures, I started using my iPhone more since that was the camera I had with me all the time. Over the past few years I've piled up quite the collection of iPhone pictures. I started so I'd have a place to share some of my favorite shots from the past few years. For this new diary series I'll be selecting images from my site that I've taken since mid 2012. (I had posted diaries for pictures from before mid '12 here (1), here (2), here (3) and here (4)).

A diary I did last year after Netroots Nation '12 got a lot of attention. People wanted to know how I did it and could I teach them how to take better pictures with their phones. I've really struggled with how I could do that without having you all come to San Diego for a photography workshop. I thought that maybe the best way to do this would be to post some of my images and talk about the rules and techniques I used to get that particular shot. We can then continue the discussion in the comments, answering your questions etc...

So, follow me below the squiggle:
