我用的是3,这个价位的都不可能很准,但是民用够了。基本可以达到95%以上。
按照大多数玩这些的人的说法,蜘蛛对没有显示设备厂商偏移数据的显示器,绝不可能有95%以上;尤其是广色域的和LED的,甚至有人反映调了还不如不调表现好。从原理来说蜘蛛根本不能准确识别颜色(所以才需要配合不同厂商的偏移数据),所以我认同这些人的说法。
当然你有蜘蛛我没有,所以不是和你争辩,只是说一下这个事情。要是真花1000多买蜘蛛,不如保险点多花点钱买个他们所谓的“卷尺”一类的,反正两三年内属于一次性支出。现在就是兜里没米,攒钱中... 下面引用些别人的看法,顺便打消下自己退而求其次买个色度计凑合的念头,呵呵。
低端的校色仪,会把你从这个偏色带到另一个偏色,不建议购买。实话说。 1d pro和蜘蛛4校出来都不对吧,怎么会偏这么多?色彩倾向都完全变了 看了大家的反应,我决定不再使用蜘蛛,我这里的体会是蜘蛛对于相对不靠谱的显示器有疗效,相对准确的显示器却是画蛇添足了!! 本人于08年中入蜘蛛3 ELite,广色域显示器校准不行;摸索了近1年后,入了colormunki photo,随后又于2010年8月入了i1 XT。 红蜘蛛elite 3和colormunki photo我都有,我认为不论是校准的精度和使用的便捷性,属于分光色度仪的红蜘蛛3都明显逊于属于分光光度计的colormunki。 如果考虑到显示器会升级,校色仪不会升级。分光光度计类型的是最基本条件,永不过时。不变应万变。才不会后悔。 蜘蛛硬件只有色度计,eyeone系列里除了低端是色度计外,高端还有分光度计,功能更强~ 我还是建议一般人别去碰广色域萤幕, 要校正它一定要用光谱计并配合适当程式, 否则你几乎无法搞定它与sRGB之间白点不同的问题. 就理论上来看, 色域愈广你愈难用便宜的校色器来校正 类似蜘蛛,I1 display2之类的色度计无法管理广色域的缘故。广色域固然好,想要骑上这好马,还要配上类似i1 BasicPro的光度计好鞍。不然,色彩无法管理,得到的只是偏色的图片,就事与愿违了。 关于色度计和广色域,一直以来都有这个争议,认为分色计搞不定广色域,但随后又有很多反驳。今天我必须要重新把这个问题提出来,分色计到底能不能搞定广色域?都已经是i1 display pro和蜘蛛4的产品线了哦!至少从针对s2433w的测试来看,似乎这两款校色器对我的s2433w这款广色域产品支持得并不好,在i1 pro的验证上。 不管用什么较色设备,一定要选择分光光度仪,不要用色度计,这东西老化太快个体差异又大。 朋友想借色度计校色,我从柜中翻出,自己先测试了下,结果让人吃惊,校色完毕的所有显示器(3台笔记本+2408)红色全部褪色严重,无需色卡也能看出极度不准。 We used the "best" set of the evaluated units to perform some quality tests.
All selected colorimeters showed an acceptable performance on the 72% NTSC
CCFL display. However, on a white LED unit, the readings differ a lot from
the reference. The spectra of a white LED unit differs a lot from a standard
CCFL it replaces and the colorimeters are trained on a specific panel type
and spectra. As soon as the spectra differs too much, the device tends to
report wrong readings. The Wide Gamut CCFL and RGB-LED readings showed - as
expected- even larger deviations. When the colorimeters are trained on the
specific panel/spectra, their readings again reach an acceptable quality.
However, the filter set of the DTP94 proofed to be farer away from the CIE
standard observer than the ones from the EyeOne Display 2 or the Spyder. It
needs therefore a higher correction for wide gamut display. Although, the
EyeOne Dispaly 2's and Spyder 3's filter may match better to the CIE curves,
they are still far off. As a result, all colorimeters need a correction for
wide gamut (and white LED according to our test). Some display vendors use
specially trained sensors for their wide gamut displays, others use standard
ones and implement the training on the specific panel/spectra in the
calibration software. The result should be always the same. But, keeping the
large deviations from (1) in mind , it's at least questionable if the single
EyeOne Display 2 or Spyder 3 Elite matches the correction curve (either in
Hardware or in Software). For the sensors that come bundled with a display,
one can only hope that the inter instrument agreement is better than with
standard retail units.
人在公众场合发言,就免不了相互影响。收集这些只是为了抵消LZ带来的影响,避免自己做出不合自己意的决定又事后后悔。希望不要反过来又影响了LZ的玩机心情,得罪勿怪! |
