Seven of the best apps for smartphone travel photography - for shots in the dark, at sunrise and more

As well as seeing where on the horizon the sun and moon rise and set (as well as exactly when “golden hour” and ”blue hour” begin and end), PhotoPills (HK$78) lets you consult depth-of-field tables, calculate star trails, and save points of interest and detailed positioning plans for future shoots.

Although other manual camera apps exist for phones, NightCap Camera (HK$15) for the iPhone and iPad is unique in that it allows you to take smartphone photos in low light, even in darkness. ISO goes up to 8,000, it stores images as TIFF files for later processing, and there’s even a built-in intervalometer for automatic time lapses. Available from nightcapcamera.com.

Ideal for editing images on the go, this “lite” version (free, with in-app purchases) of the famous Adobe Photoshop software has a good basic suite of controls, though you do have to buy add-ons for noise reduction processing and many other things. It makes it easy to upload edited images to Flickr, Instagram, Facebook, Twitter and WhatsApp. Available from adobe.com.
