50X

The images in this photographic series were taken with a digital cell-phone camera set to capture at its extrememost, 50X zoom level: by definition, a subjective measure of magnification. Details are distorted, edges are hazy, and colors are bleeding and merging with each other to form a fluid landscape of emotions, all equally powerfully contributing to create what was experienced, at the time, as a profound spiritual stillness. This series forms part of a work in progress exploring the dual conceptual themes of the Pleasure Garden and the Ghost City – metaphorical spaces that encompass living presence while being concomitantly encompassed in it.

The time-base displacement error is a major problem caused by the change in magnetic tape speed, which, although small, is enough to degrade the picture. A 1-megacycle pilot tone is recorded on an adjacent track on the tape and the zero-crossings of this pilot are used to key the sampling circuitry. Thus, regardless of the tape speed, the digital sampling is always referred back to real time, and time-base displacement errors are eliminated. Since the information bandwidth goes to 200 kc, at least 400,000 samples per second must be sampled according to the sampling theorem. A 500-kc rate is used for sampling, and each one of these samples is defined as a picture element, or pixel.
Ώς οἱ μέγιστοι τῶν θεῶν καὶ φίλτατοι τῇ πόλει πάρεισιν! Ἐνταῦθα γὰρ Δήμητρα καὶ Δημήτριον ἅμα παρῆγʼ ὁ καιρός. Χἠμὲν τὰ σεμνὰ τῆς Κόρης μυστήρια ἔρχεθʼ ἵνα ποιήσῃ· Ὁ δʼ ἱλαρός, ὥσπερ τὸν θεὸν δεῖ, καὶ καλὸς καὶ γελῶν πάρεστι σεμνόν. Ὁθιφαίνεθʼ, οἱ φίλοι πάντες κύκλῳ, ἐν μέσοισι δʼ αὐτός. Ὃμοιος ὥσπερ οἱ φίλοι μὲν ἀστέρες, ἥλιος δʼ ἐκεῖνος. Ὦ τοῦ κρατίστου παῖ Ποσειδῶνος θεοῦ, χαῖρε κἀφροδίτας.
