A fine question. As presented currently in Tonfotos, at least graphically, it’s a strictly linear, top-to-bottom timeline. And while this certainly encompasses specific ‘events’ - eg, a family vacation, a wedding, etc - it also includes all of the random, spontaneous photography that occurs in the spaces between these larger, more formally defined events, which ultimately probably constitute the majority of any personal image catalogue. As such, calling this an ‘event’ view is something of a misnomer. Following this line of reasoning, while ‘events’ will have memorable dates, one may be less likely to remember the date of “that weekend that Frank came over, and we got the drone stuck on the roof, and when we went up to get it, took some glorious landscape shots at sunset from this unique vantage point…”. Seeing those photos overlaid on a calendar, from a graphical perspective, provides a greater sense of time and place than a strictly linear event line, devoid of additional spatial/graphical context. For example, those great landscape shots taken spontaneously from the roof might have occurred the first weekend in August, but, on a linear ‘event’ line, they’d be immediately adjacent to photos from, say, your niece’s wedding, which was in late October. Since most people are accustomed to looking at days/dates in calendar format, a monthly calendar display showing sets of photos on the first weekend in August, followed two pages (ie, months) later by wedding photos overlying a late October weekend, provides a graphical/visual representation of the temporal relationship of these ‘events’. In short, to me, anyway, it’s kinda like the difference between an analog or a digital watch. Sure, a digital watch will tell you that it’s 10:37AM, so you know that you have 23 minutes until your 11:00 meeting, but an analog watch can convey the same information, while also providing a visual/spatial representation of what 23 minutes represents on the face of a clock… Hope that makes at least some sense…
