Times of Day for the Best Images: Golden Hour One for iOS (Updated and Amended_
By Graham K. Rogers
BackgroundThere is not much that can be done about the sun (or its lack) when shots appear spontaneously: those candid or lucky shots that occur every day when we keep our eyes peeled. When planning to visit a location, however, it is helpful to know where the sun (or moon) will be so that decisions can be made on what to photograph, when, and how.
For over 4 years now, I have made use of LightTrac, which allows me to see sunrise, sunset, moonrise and moonset, as well as tracking the paths of those bodies, either at my current location, or anywhere else, with satellite or map view.
An app that has recently appeared in the App Store here is Golden Hour One. This is shown at 69 baht, but I bought it at 35 baht (18 May). I checked with two other iPhone users and the price was shown as 69 baht for one and $1.99 (she uses the US Store) for the other. I submitted a query to Apple on this apparent discrepancy (see below).
Golden Hour One adds a little refinement to the tracking information by showing information about these two times, which differ depending on the user's location.
Golden Hour OneThe app opens with a 24 hour clock display, showing the respective times for Golden Hour and Blue Hour, morning and evening. Three times and three time bands are shown on the clock for morning: Blue Hour, Sunrise and Golden hour. In the evening, the order is reversed: Golden Hour, then Sunset, followed by Blue Hour.
Beneath the clock is a button that can be used to select Sunrise or Sunset. Depending on the choice, the times for each for the current day are shown just below. Pressing on the day/date display reveals a scroll wheel so that any date from 1 January 2015 up to an unforeseeable future (I stopped at 2625 CE) can be shown.
A slider at the bottom allows the date to be adjusted: 1 January 2017 to 31 December 2017. Using this I was able to visualise sunset conditions for when I will be home in the UK later this year. The Maps data and other input require GPS and this may not be available at all times.
A Weather option shows light conditions for the selected location and shows a Sky Index and a Light Index. This only appears to be for the current week (hard to predict next month, of course). Comments were helpful: for today at my office the morning was "Broken high clouds. Poor chance to catch sunrise". Even more to the point, the Evening comment was "Overcast. Forget it."
A Reminders page had nothing scheduled and I was unable to see where in the app any such scheduling could be saved or how. More shows information about the app, including settings (Location, Notifications, Cellular Data - ON/OFF).
In UseEven in the few minutes before the evening Golden Hour, photos taken away from the sun are crips, while those taken facing the sun (and there was some haze when I tried this) are less sharp. Foreground light levels are also affected.

CommentsThe use of Golden Hour One itself adds nothing to the photographs I took, but that is not its purpose. By using this, and other apps, like LightTrac, I am better able to make use of the position of the sun (and moon) so that I am aware of light conditions beforehand, allowing me to prepare for a specific location, or making sure that I am ready to take photographs at the best time.
Amended information re pricing: I contacted Apple over the pricing differences and it was suggested I contact the developer, Hana Kusova. A quick reply told me that the actual price is higher ($4) and at the time I bought it she was experimenting with an optimum lower offer and that the pricing has now returned to the normal level ($4 or 135 baht). It seems I was lucky.
If I were so inclined (and I am not a morning person), I could use the information from Golden Hour One to set my alarm clock and leave home in time for those cracking early morning shots that others are able to take. As such this app is of value to those who need this type of information and is recommended as it is sound for the purpose.
