Sorry we’ve been busy with other things so we haven’t got a chance to update the apps for quite a while. It turned the new Android versions don’t work with some of our old code very well. It causes some serious freeze issues on most of our apps (ruler, level, protractor etc.) We found out what’s going on and released a new versions for all those apps. As far as I can tell, all apps should work fine now on most of the phones. So sorry for the late updates.
There were a lot of complaints about the Advanced Tally Counter where the name of the counter is not showing. The root reason was discovered and a new update was posted for both the free and the paid version.
Advanced Protractor Pro
Last but not the least, we updated the Advanced Protractor Pro to include a neat feature – to help Photographer to find out what lens to bring for a particular location. Well, it sounds like nothing to do with a protractor when you first hear this. But here is how it works.
What lens to bring is a question that all photographers will ask themselves before going out for a photography trip. Sometimes it is a tough question. Bringing them all is an easy answer but not an easy decision for a strenuous hiking. This Advanced Protractor Pro will help you to scout the location beforehand and help you making the decision.
Last winter, I went to the famous Horseshoe Bend near Page, AZ. My first question, before I went there, was what kind of wide angle lens I would need in order to capture the whole bend and the side cliffs. I went to the Google Map for help. If I have a real protractor, I can put it on screen to find out the angle of the span, then use an online angle to focal length converter, I can figure out the lens focal length. But isn’t our Advanced Protractor Pro is a better protractor? This triggers me to add this new feature.
First, you go to settings to change the display of the angle degree to focal length.
Next, long press and hold the multi-function round button so that you can see three green circles on the screen. Now press Menu – Toggle Camera to turn on the camera.
The next step is to use your computer to open the Google map to navigate to the place you are interested in. Use the app camera to take a picture of it. (Yes, we plan to release another app to show the Google map right in the phone but here is what you have to do with the app right now)
Now you can drag the handles on the screen. Put the center one at where you will stand when taking the photo. The other two handles at the widest angle that your photo will cover. In this case below, I will stand at the rim of the cliff to capture both walls. The focal length calculated by the app is about 18 mm (or 12mm if taking picture vertically). Note that this is the focal length for a full frame sensor in the landscape mode. If you have a crop sensor, you need to divide it by 1.5 or 1.6 whatever the crop ratio is. You also need to adjust it if you plan to capture in the portrait mode.
Is it for real? Yes of course. Here is a picture I took last Winter when I was there. As you can see from the EXIF information, I used 17-40 lens at 19 mm.
Here is another one. If you want to capture both the Half Dome and the two falls (Vernal fall and Nevada fall) from the Glacier Point, you would need about a 32mm lens or 21 if vertically. If the cloud is interesting, you probably will take the picture vertically thus a wide angle lens such as 17-40 or 14-24 is certainly required.
How about the Bellagio music fountain? To capture the whole fountain needs a really wide angle lens, probably a fish-eye. But a nice composition is to capture both the Bellagio and the Caesars Palace hotel buildings as background and use the fountain as foreground. The app tells me it is 19 mm.
I actually use a 17 TSE so that I can more room to crop and also be able to shift the lens to get rid of the distortion for the high buildings.
Obviously, I hijacked the Protractor Pro to squeeze in this extra feature. I only spent an hour or two to add it. It is clearly not enough. The next app we will do is to create an app for Photographer do something like it but it will do more. Please stay tune.
