數位科技發展迄今已有將近30年的歷史。「數位化」從生活中的各個角度，帶給我們有別於傳統的類比感受。
數位化，是將連續的類比資訊，以高速取樣的方式切割成細微的瞬間數值，再以電子科技加以重現。數位化的目的，使得我們可以使用電磁的方式記錄、傳輸，而不致因為時間久遠而喪失資料的訊號強度，得以精確的保持取樣時的精準。
然而這些數值因為取樣當時的速度與解析能力而過於粗略時，就會產生可被察覺的顆粒、鋸齒狀的階梯數值。這種現象即是數位科技所帶來的–「不連續性」。例如，數位影像從過去單色無灰階，到現在動輒數百萬像素、全彩的超高解析度畫面，使得我們幾乎感受不到數位化的特色–「不連續性」的存在。
「數位」一詞，一直都是我們所認為的「高科技」與「先進」，但曾幾何時數位生活在短短數十年間的演進，已讓我們忘記了數位產品初發，這些低解析度的過渡產品，反而是相當的令人莞爾與懷念。
「數位印記–廖克楠個展」，主要透過低傳真度的表現，來喚起並討論這一連串數位化演進過程中，所造成我們對這些數位生活中的「印象與記憶」。

Concept of Work
Digital technology has been developed over 30 years. From each view in life, “Digitalization” gives us the difference from traditional analog feeling.
Digitalization will slice continuous analog information as instantaneous values by high-speed sampling to reconstruct with electronic technology. The purpose of digitalization allows us to record and transmit by electromagnetic manner without signal loss in long term to obtain accuracy during sampling.
However, the observed grain and zigzag ladder values will be produced when these values are excessively rough due to sampling speed and resolution in that time. This phenomenon is “discontinuity” produced by digital technology. For example, digital images transfer from monochrome and no gray level in the past to million pixels and full-color resolution screen nowadays, so that we almost don’t feel digitalization features – the existence of “discontinuity”.
We always considered the term “Digitalization” as “High-tech” and “Advance”, but with the evolution of digital life in several decades, we already forgot the early development of digital products. These low-resolution transition products are interesting and nostalgic.
