Pentax 645D Hands-On Field Test
http://www.youtube.com/watch?v=7wPD1wRpels&feature=related
As shown in this video,weatherproofing is very essential for landscape photography.
The Pentax 645D is billed as completely dust and weather sealed.
It is also billed as having cold resistant performance and a -10°C temperature rating.
Conventional digital MF gear may not has this feature.

Ansel Adams print sells for US$722K at NYC auction
http://spoolphotography.wordpress.com/2010/06/
Posted on June 22, 2010 by Neal Pritchard
Wow …
Came across this new article today about a photography auction in New York City ,
while reading the daily news this planet has to offer and was stunned that a photograph could be worth over US$700k.
I know it's Ansel Adams and I would dearly love to have one of his originals one day, but US$700k that's huge …
and I think that's a good thing, photography sometimes gets overlooked as the poor cousin to those that paint or do sculptures for their art …
One could only dream of selling an image for that much,
right now mine are less that 1% of that price, does that make it a good buy now ….

Photography, Art or just a photo?
http://www.spoolphotography.com/ ... rt-or-just-a-photo/
Do you consider your photography art or just photography?
Recently I read an article on a blog I visit often
Edward Mendes wrote about this subject matter here
http://www.edwardmendesphotography.com/blog/?p=216
and its something I guess we ask ourselves from time to time in the same vein as being a professional or an amateur photographer/artist.
While the term Artist has been reserved for those that either produce painted works or sculpture pieces do we as photographers professional or amateur consider ourselves artists?
While I consider my photography art others may not,
I believe the term “Art” lies in the eyes of the beholder as I have seen many “Art” pieces I thought looked like twisted pieces of junk metal or paint just splattered all over a canvas.
Do you need a “Art Degree” to understand what art is or can you find art in something you like regardless of what the next person thinks?
Edward makes a good point about the work and vision photographers put in their craft both on location and in post production,
is that not the same as a Artist that see’s a scene either in nature or in their mind and then recreates it using paints of other materials like wood, iron or stone.
Or is art a product of somesone’s passion to bring to others that same thing they see or hear as a vision first then bring to life via their chosen art filed, painting, acting, making music or taking a photograph?
or maybe Art is more the intent to produce something rather than document something, we can all take a photo to document a location, while some will try and produce art through their knowledge and skills learnt.
What are your thoughts when one person takes a photograph then just sends off the raw file image to a 3rd party for post production, receiving the finished product back from someone that was never at the scene to understand the light, colours at the time ?
Comments
Photography Art Cafe said March 14th, 2011, 9:41pm:
I think some photos definitely have something of art about them, but it’s hard to define what it is !
I think it has a lot to do with how well the photographer is able capture something as only they could have seen it.
Some photos can be as distinctive in terms of who created them as some paintings.
There’s definitely something beautiful about photos.
The extreme realism is sharp and clear and satisfying.
But ‘art’ photos make you go back again and again and somehow –
no idea how – they keep holding your interest.
There’s depth to them and originality.
Technically brilliant paintings can sometimes actually be really uninspiring and cliched.
So I think the key ingredient of art, that somehow makes the viewer part of the image, can exist in both photography and more traditional mediums.
Tim Wootton said March 15th, 2011, 9:31am:
This is a debate that will probably never stop !
Art covers such a lot of mediums and photography is certainly one of those mediums.
Since the advent of Digital photography and Photoshop, photography has morphed into something that can go way beyond just gathering light from a scene in front of you.
More than ever the camera is just the implement to collect the raw data that your imagination and software can turn into real art. From there it is in the eyes of the beholder!
The beauty about photography is that it can be purely functional ie:forensic or product photography, artistic such as advertising or fine art, or a mix of both such as landscape and fashion.
My take on it is that if someone likes it enough to hang a large print on the wall then that print is art !
Neal Pritchard said March 16th, 2011, 11:35am:
I agree with that Photography Art Cafe, but is it still considered art when someone takes the photograph and outsources the post production of the image as is the case with a growing number of home grown photographers …
I agree Tim but the same question remains, is it considered art or just a photograph if 2 people are involved where one person outsources their post production …
Greg Rowe said April 4th, 2011, 10:53am:
My view is that landscape photographjy can definately be considered as fine art.
It depends on the creative intent of the photographer when the photo is taken and the post production where the artist/photographer interpets the image through his mind and heart.
To me it is only the end result that is important, it doesn’t matter how you get there. I try to capture the spirit of place exactly the same as a painter or a poet would.
We live in a beautiful landscape where we cam merge our internal world with the one that surrounds us.
Photography Art Cafe said April 4th, 2011, 11:29pm:
Interesting point Neal !
I think in all liklihood ‘No, it can’t’.
But not by definition.
Some art relies on collaborative effort, e.g. theatre/music.
Some simply survives the involvement of secondary contributors,
e.g. redacted literature/large scale paintings or sculpture.
But I think what makes some photos so cool is that they reflect the uniqueness of the photographer’s vision,perspective, observation etc.
There’s just something different about them.
The graphical elements of the picture fall into line with this, so why would anyone want to outsource Photoshop work?
I can understand it if it’s purely for commercial reasons.
I totally agree with Greg above – it’s the ‘end result’ that matters in photography – and you wouldn’t want anyone else getting in the way of that !
Neal Pritchard said April 5th, 2011, 8:03pm:
I have no idea why some would outsource their post production and loose final control on what they saw, unless they saw nothing in which case to me it just becomes a snap shot with no insight and style from the photographer which usually leaves the photograph looking cold and as I said just as snap shot …
Pat Remedios said April 9th, 2011, 7:55am:
I think it must be Art because one has to have the GIFT to be able to capture NATURE in its TRUEST FORM.
Anyone can be a Doctor or Teacher etc., but it takes true Talent or Gift to produce healthy results.

Pentax 645D VS Phase One P40+
Details as follows-
http://www.luminous-landscape.com/reviews/cameras/2010_mini_medium_format_shoot_out.shtml
Conclusion
I proposed this test to Mark hoping to prove that the Pentax was at least in the same league as the Phase – an instrument I have the utmost respect for.
The final results are more than I had hoped for.
In this field-test at least, there is nothing to separate the cameras beyond the 645D’s superior high ISO performance.
In studio, I suspect that the Phase would be better, but that remains a supposition.
Since the Pentax does not allow a professional tethering solution, there is little danger that it will find many adopters amongst high-end commercial studio shooters.
In its native habitat, however, the Pentax more than holds its own.

Pentax 645D Action Photography Video
Ryan HK went out to shoot the advertising images for Canada Olympic Park with a Pentax 645D,
and his lighting technique and shooting process was filmed as follows --

Snowboarding and the Pentax 645D
31 03 2011
This week I was booked to shoot some marketing material for Canada Olympic Park.
As some of you know I shoot a fair amount of Medium Format, even in sports.
On Tuesday The Camera Store gave me the Pentax 645D to try out.
They wanted to shoot a behind the scenes video of sports and “Medium Format” cameras.
The Pentax performed great all day. I was used to the focusing speed on the H series from Hasselblad and this new Pentax was a real treat as far as focusing speed goes.
Unlike the Hasselblad digitals and Phase One backs that both shoot in 16bit RAW, the Pentax shoots 14bit, similar to a Nikon Raw format.
I was initially a little concerned about this, for large prints.
After working a couple of the files in PS, these 14bit files are stellar.
There is a large selection of both focal plane and leaf shutter glass available for the 645D.
This is a nice little bonus, as my Hasselblad system has a very limited number of lenses available.
The Hassy is also only “leaf” shutter, so you are limited up to 1/800th of a sec for shutter speeds.
The Pentax 645D’s ability to accept both leaf and focal plane means you are able to jump up to 1/4000th if the job requires it.
For about half the price of an entry level Hasselblad or Phase system, the Pentax is a killer choice.
I can definitely see this camera making a larger presence on the lifestyle and wedding circuit.
The 645D has the ability to give you that unparalleled fall off and D.O.F. in a medium format (not to mention it shoots a native 18×24 @ 300dpi).
We shot for about 4hrs on Tuesday and the Pentax battery barely dropped a bar.
Usually when you’re shooting winter sports the batteries in the bigger cameras take a pretty big hit.
This camera held up throughout the shoot.
For those of you only running laptops to do your editing and worry that a digital medium format file will bog down your system to no end… Don’t.
The files are a modest 50-70mb each, and being 14bit, they won’t murder your machine’s RAM, whether you use PS,Lightroom or Capture One.
Overall, we had a great day of shooting at C.O.P. and I really enjoyed shooting with the Pentax 645D.

Pentax 645D is selling quite well in most world markets
Michael Reichmann,author of the Luminous Landscape site,has the following added comments about Pentax 645D on his recent article about Sigma SD1 -
http://www.luminous-landscape.com/reviews/cameras/sigma_sd1___ready_for_prime_time.shtml
Pentax was able to price its 40MP sensor-equipped camera at under US$10K, because they were willing to commit to a high volume sensor buy.
That gamble seems to have paid off,because Reports are that the big Pentax 645D is selling quite well in most world markets.
People are also used to buying expensive medium format cameras from Pentax,and have been for decades.

我最後的想法在 Pentax 645D & 樣本圖片
http://www.pentaxforums.com/forums/zh-TW/pentax-medium-format-645-6x7-645d/139755-my-final-thoughts-645d.html
這是我最後的想法在Pentax 645D 和彙編作品在過去的六個月。
總之,Pentax 645D 是一個偉大的價值,那些誰認為打印的質量最高的優先級。
圖像質量
(1) 每個像素點的質量最有可能超過任何高端 單反相機,不知道如何比較其他媒體格式位數七段。
(2) 圖像銳化非常好,比D3X的,件1DS III或5D條二,RAW文件包含細小的細節,少磨工件時,用同樣的參數在ACR的(相比於 100%)。
(3) 實現泛焦更加殘酷的風景攝影師由於傳感器尺寸較大。對於像素的同輩人,如果你要求高品質的每個像素,這意味著很 小的圈子混亂, 自由度 將永遠是一個問題,當您包括特寫遠處的物體(如少於 10 - 15英尺,當您拍攝在35毫米,f/13),重點是你堆放可能要考慮的問題。
(4) 動態範圍似乎沒有什麼不同,比任何其他數碼單反相機,規格從製造商似乎支持我的經驗。
(5) 產生更好的圖像使用ISO 100比ISO 200(ISO 200時,即使是默認的),雖然我沒有測試以上ISO 400。
(6) 色彩還原是很自然的。紅色通道往往被壓制相比,佳能數碼單反相機(也許這是其他方式,佳能往往oversaturate)。
(7) 可怕的白色平衡。特別是拍攝日落和日出給你一個數字的物流挑戰,汽車 世行 幾乎從來沒有的權利。需要採取心理圖像的場景和正確的 世行 在RAW轉換器\u200b\u200b的記憶。
(8) 在f/16衍射變得明顯,最好的光圈似乎是f/11-f/13為風光攝影。
相機
(1) 絕對大於任何頂級數碼單反相機的路線,但其規模輕。
(2) 符合人體工程學設計,處理得非常好。
(3) 感覺很紮實很好的問題,灰塵 /天氣密封提供了極大的保障。
(4) 取景器大而亮,顯示所有必要的信息。
(5) 鏡子是很好挫傷,鎖定是非常有益的景觀射手。
(6) 電子水平儀,方便,準確,還提供取景器內。
(7) 非常有用的專用控制按鈕 /旋鈕為 bracketting,鏡鎖定,計量, 自動對焦 模式, 自動對焦,白平衡和驅動模式。
(8) 電池壽命是綽綽有餘的,購買了3額外的電池,從來沒有使用兩個以上的電池,在一天。
(9) 單獨的安裝板可以貼在左邊為垂直的攝像機鏡頭,非常有用的,因為有些球頭的重量不能支持的相機時,傾斜。
(10) 3“液晶顯示器是一個最好的特點,精湛的質量。相機提供了快速放大檢查對焦 /清晰度(通常是放大到14倍,16倍給你一個良好的意義上是100%原裝)。
(11) 似乎是準確的自動對焦,也沒有機會進行精確測試。
(12) 缺乏實時查看是一個重大的缺點相比,高端數碼單反相機。
(13) 大約需要4秒,檢討了一槍甚至32GB的SDHC卡的SanDisk Extreme(30MB / s的),(帶鏡頭更正關閉),可以不時令人沮喪。
鏡頭
(1) 大多數足協鏡頭似乎執行得很好例外的FA 33 - 55mm的和FA 45毫米。測試鏡頭:足總杯 35毫米,足總杯 33 - 55mm的,足總杯 45 - 85毫米,足總杯 55 - 110毫米,足總杯 80 - 160毫米,45毫米足總杯,ð發 55毫米,75毫米足總,足總 150毫米。
(2) 英足總的35mm稍微優於 35毫米,雖然質量非常邊緣與 645全畫幅傳感器,仍有待觀察。
(3) 似乎提供了一個更大的35毫米 自由度 比足協三五毫米集中在同距離具有相同的f值,可能是由於以下場曲。一個測試,不久將進行。
(4) 足總杯 33五十五毫米幾乎 unusuable用於像素的同輩人,由於極端場曲,它從來夏普公司從角落到角落低於 f/16,所以幾乎總是大大衍射極限。鏡頭從 35mm到性能更好45毫米。兩份測試,同時校準賓得日本。
(5) 足總杯 45八十五毫米和FA 80一百六十零毫米足總杯表現略好於 55一一○毫米,所有三個鏡頭產生非常清晰的圖像。
(6) ð發 55毫米,似乎在一點點柔和的邊緣比足協 45 - 85毫米,但在中心稍微清晰的框架,鏡片都表現非常好。
(7) ð發 25毫米,是在它的方式,將報告早在幾個星期。
打印
(1) 經測試高達 30“X40的”,提供了巨大的品質和驚人的細節。
(2) 預計將提供打印高達 39“× 52”這是雪亮的仔細檢查後(假設 1.5英尺觀看距離)時,正確處理和激化。
改進建議
(1) 80MP全畫幅傳感器。
(2) 發展傾斜鏡頭(控制焦平面,避免衍射)。
(3) 實時查看。
(4) 改進白平衡。
(5) 更快的影像檢查。
(6) 鉸接式液晶顯示器。
一個雞蛋裡挑骨頭
該工廠遙控器F有一個小小的按鈕。這是棘手的使用,因為你必須按它與你的指甲,且有時你最終錯過了一槍。售後遠程功能按鈕更大,更便宜,效果更好。
