Interesting but Limited Artistic Effects from a Free IOS App: Trigraphy
By Graham K. Rogers
And now Trigraphy appears. It has actually been around since December last year, but this week is included in the Best New Apps section of the App Store here with a new name. In its earlier versions it was simply called Tri. The new 3-syllable name is a little more memorable.
The concept of taking photographs and applying artistic effects to them is not new and there is some stiff competition, most notably from Waterlogue, an app I reviewed at the end of 2013 and make use of often.
The app opens with a panel detailing changes in the Trigraphy update, but once this is cleared, we see the two import options of Photos and Camera. I prefer using Photos, in case a new app does not retain the original image. Once I had granted permission for the app to access the Photos Library I selected an image but noticed that the import was slow as the initial effect was applied (depending on the selection) as the image is brought in.
The strength of an effect can be altered, on a scale between 1 and 100 by sliding the finger across the screen to left or right. This can have a significant effect on the output, from something that is quite recognisable to a picture that is almost abstract.
System Share accesses icons to allow export via Mail, Message, to Twitter, Facebook and other such sites if active, there are also other controls (such as copy and print) as are available in other like apps.
When saved in the Photos Library the images as synced to Aperture were each 730 x 1334. The lotus images varied in size: 82 KB, 401 KB and 1.18 MB. This seems to depend on the density of the effect applied. The wine/cheese image with an effect applied of 1 was only 26 KB but had the same dimensions.
By upgrading the free version to Trigraphy HD for $1.99 users are informed that the image size can be increased to 2560 x 2560 (depending on input dimensions) and the watermark is removed. However, on the images I saved, I am unable to see any watermark.
If users want an app that turns their photographs into artistic output, this is not to be ignored.
