多采多姿的獵戶天區

最近大家期待的，是他推銷的5" PV赤道儀，能夠出什麼水平的照片。至少一個個好好的品牌，都毀在他手上了。

This is wrong! According to his theory, he said his new mount has 2.94" P2V. The 5" P2V is for AstroTrac.

幸好他沒有用什麼我賣的東西，否則人家以為他是我的推銷員，是我跟他蛇鼠一窩弄虛作假欺騙顧客就麻煩了，你看多少個品牌都毀在他手上？

Use Lab color ( a & B) in CS4 to enhance colour version . This method can increase saturation without creating so much noise .

[社長]

OMG

this version is much better, thanks Ben and please teach me next time we meet.

may be I stack and send you the 150s, 40s, 10s exposure RAW tomorrow, so that you can do layer mask to enhance the details in over-exposed areas.

Ben,

確有一手！那種 Lab color (A&B) 是什麼一回事？可否介紹一下！

[benben88]

In PS , go to mode > change from RGB to Lab > apply s-curve in a&b layer to adjust contrast n saturation . Then switch back to RGB

Thanks Ben,

I really hope to have a chance of learning these Photoshop skills in a sharing session.

[社長]

Ben，現人在廣州，會儘快疊加其他曝光後請你幫忙做layer

[社長]

已加了4個曝光的原圖，及發PM請大家幫手處理，我或許會在3月下旬再去，繼續增加曝光，但希望先為1月份拍的這張照片作個小結，看究竟七小時拍獵戶天區是什麼樣子的
