ProHDR and Sunset

After a full day of rain on Friday I was walking home from work and the clouds finally broke up just before sunset. I looked behind me and the clouds were nicely lit up by the sun with the restroom doors of our outdoor pavilion just below them. I pulled out ProHDR and snapped a shot.

Around sunset using an HDR (high dynamic range) app can be very useful, depending of course on the effect you are looking for. In this particular case the two typical shots would be those below. Using an HDR takes the best of both shots, which is really drastic in this situation.

Even though the picture wasn’t exactly a natural wonder or anything like that, you can at least see the nice effect you can get with HDR on the iPhone as the sun is heading down 🙂

ProHDR is just one of several HDR apps available for the iPhone, but it is still my favorite. I wrote about several others in this previous post.

Creating ‘Tiny Planet’ Artwork Using Several Apps

I recently posted a shot over on Flickr (Tiny Jesus 1) that used several apps to create something interesting (at least in my own private world). I’ll walk you through that process for anyone that may be interested.

The first thing is that I was taking a few shots for possible use with the Tiny Planet Photos App. One thing that helps to get interesting shots with that app is to have matches on the left and right side of the image. When the spherical filter is applied in the app the even edges allow for a smooth connection in the image.

Here was the original shot I took (using Pro HDR).

I trimmed the image a bit so that when using Tiny Planet the cross would not get chopped off on the top.

I used Photogene to tweak the levels a bit. Then, since there was a chuck of wire in the image near the cross (click on image above to see it clearly), I used TouchRetouch to remove the distraction (TouchRetouch is a rather amazing app!). The touched up image is shown below.

You can see that the left and right sides of the image are lined up. I then put the image through Tiny Planet and got this output.

At this point I wanted to increase the “space” above the cross, since I didn’t want that to be directly next to the edge of the image. I used one of the MANY transformations in PhotoFactory to increase the image size. That feature begins to mirror the image on every side. This image shows the control for that feature, and the other image shows the output from PhotoFactory.

I used TouchRetouch once again to get rid of the extra cross at the top.

Then I cropped the image a bit on the left/bottom to center the church with Photogene.

At this point I used ToonPaint to create a new black & white version of the image. In ToonPaint I use the Size controls with settings of L, S, and S for the three parameters. I then tweaked the Shading a bit to create this image.

At this point I fired up Image Blender (another superb app). I placed the colored image on the bottom and the B&W on the top and selected Luminosity for ink. I then tweaked the slider until I was happy with the image.

And finally, I pulled the image into Camera+ and selected the frame option, and applied an effect that I liked (I actually saved multiple versions using different effects since I liked a few of them). And after all those apps I ended up with the image I put on Flickr.

Fun! I also did a version where I used PictureShow to apply some noise and filter. That one is also on Flickr.

You can do a lot with a single app, but often a few are needed to get the shot you really want. Now…if only I had a bit more artistic talent. At least I’m having fun 🙂

HDR Fusion App = Very Fast HDR

For those that enjoy HDR photography, HDR Fusion for the iPhone is a good app to have with you if a quick capture time is important. This app boots up and captures shots very quickly. To take a photo you have to click on the standard camera icon at the bottom of the screen (it is not a full tap screen). You can set a delay of up to 10 seconds before the shutter fires and the final image size (I always go with large).

When the shutter fires you’ll notice a crosshair appear in a bright region of the screen, and a few moments later the dark region. It does this light/dark analysis VERY quickly compared to other apps I’ve used, which is very nice if there is a bit of motion in your shot. The two images have now been captured and the app begins to fuse the two shots together. Once fused you get the option to save the shot or cancel.

This app is really fast when capturing the two images, and the HDR shot is rather nice. I often find it just a bit warm in some situations, and the contrast seems a bit low in some shots. You can always choose to deal with those issues in other apps if you need to, but HDR is often a very personal choice 🙂

The following images were all captured on the fly with a handheld iPhone, and the exact position is not identical between shots. I also reduced the size a bit (in future I’ll post things to Flickr for full size – still debating what to do with some things on this blog), but you can click on the image for a slightly bigger version.

This first image was captured with HDR Fusion this afternoon. I also grabbed shots using the built in camera with the HDR option turned on and Pro HDR (I’ll definitely discuss this one in the future).

This app does not allow you to choose to different exposures from your image library and doesn’t save the two different exposures to your library as can be done in Pro HDR.

I highly recommend this app if you are interested in quickly capturing HDR images in those cases where it is important.
