Thank you Ed.

Lu-La has always been my guilty pleasure! 

I like your portraits of Theologists.  It's a nice series.

Have a good shoot!

Welcome aboard Jeffery, it's always nice to have yet another professional who is willing to share experiences in a constructive rather than a destructive manner.

And thanks for the compliment!

Were those shot with a LS55 ?!?! Red doughnuts of confusion everywhere !

Very nice pictures by the way  Kiss



You can name drop the photo editors of magazines, but we all know perfectly well that you don't need massive resolution for editorial photography.

People magazine... it's 8x10 and hardly known for high image quality. Celebrity gossip magazine.

As for your on not having time to dick around with Speedlights While I actually use many types of lights.. Tungsten, strobes, HMI etc
I often use speedlights (Canon and Nikon) in particular when I need some extra speed. This is often due to time constraints and working with
A-List clients whose time cost many times my rather high rate.

Here are a few examples of shots taken with Speedlights.


Lady Gaga


Shaq


Kristen Stewart


Ben Affleck


Rev. Al Sharpton


Rammstein


Evan Rachael Wood

All taken with speedlights and my custom modifiers.
I can even hand hold the speedlight in one hand and camera in the other changing the light angle
with every small movement of the subjects face to get exactly the right shadow on the eyes.
I've developed a knack for reading the preview "pilot lights of sorts".

I also use strobes when I want to. Actually my biggest investments are in lights.

Regarding the 1/1600th of a second thing with LS shutter and Prophoto...
I have no problems shooting up to 1/8000th with the D800 and my Elinchrom Micro 6000 w/s and 3000 w/s packs.

Doug may simply have fallen victim to the bent field of focus and had trouble focusing.

Anyone have any popcorn ?

"different level of edge sharpness"  This image you posted is obviously heavily sharpened, edge contrast level being one of the characteristics of edge contrast.
Edge contrast is one of artificial artifacts of sharpening. When it is a visible as it is in the image you posted it is obviously heavily sharpened.
Posting a heavily sharpened image to demonstrate the sharpness of a lens is ... rather silly to say the least.

The signs of sharpening are so obvious:

My P65+ and IQ 180 shots with the 55mm LS seem to be tossed out as it was a test when I first tested the IQ 180 and a prototype 55LS. But I do have a couple from the P40+ which PLEASE dont remind me its a crop sensor , we are all not that stupid. I said it was a great lens on a Full Frame sensor and your just going to have to take my word on it or not. Frankly reading this thread is some lame comments from people that never shot it, tested it or owned it. I really wonder how in your right mind you can make comments on vapor shooting something. I'll never understand the armchair quarterback thingy. Oh well as B.C. said the internet is free. ROTFLMAO

I'm really not sure why i am even posting this stuff as i know for a fact it will get turned into something other than some decent shots with a nice lens. Maybe I'm the stupid one for even trying to tell the truth.

Anyway I actually shot these at F16 which I'm somewhat surprised I did that except for water movement I was trying to slow down.

B&W image shot for 6 seconds at F16
Color image shot for 3 seconds at F20 which I was forced into shooting at that small aperture. I dont really see diffraction in this one as i knew it was a risk shooting this slow.

2 more from the same time frame both at F16 and one was 3 seconds and one 6 seconds and I am remembering using ND filters on all of these. Since we realized at this altitude we needed IR ND filters instead. Yosemite about 9k feet.


The first image I am focused fairly close up.

Guy, could you please add 100% crops of the relevant area, it's impossible to evaluate the sharpness from web resolution pics. Thx.

Hard to tell at Web resolution.

Nice shots. In particular the black and white.

The images are nice at this resolution, but are shot at F16 and F20 with a crop sensor. The MTF curve shows improvement just going from F5.6 to F8 as far as leveling off of the
roller coaster shaped curve. While there is some diffraction many other problems go away when you stop down. Things even out. Relative illumination levels out too.


It would also be interesting to see the black and white in RAW, Sky seems a bit on the noisy side for a straight ISO 100 with a DB.

Paul if your seriously interested in the 55LS lens I have plenty of images shot with the p40 and IQ 160 that PROVE the REAL reality how good this lens really is .......

My P65+ and IQ 180 shots with the 55mm LS seem to be tossed out as it was a test when I first tested the IQ 180 and a prototype 55LS.

Pity no full frame shots. What about the IQ160?
Pity you tossed them out. I always keep tests I like.

Sky is burned in. I would not use it as any reference a lot was added there. FF Images are buried or tossed , sorry no time for dealing with that or doing crops. I pulled these from images I already posted on my forum. My time the last 3 weeks and going forward for awhile is dedicated to a family member so I won't get to anything further. Sorry. My family comes first right now.

Hi Henrik,

I think this an unappropriate question to ask. Guy is very open about his relation with Phase One.

He is a long time user of Phase backs. He also holds workshops at GetDPI.com and also acts as instructor at some Phase One Workshops.

I'm certain that what he writes is his honest opinion. Guy is also a guy who has been there and done that, check out his web site.

Phase One i a small company and it seems that dealers they have in the US are quite involved with the company, you know dealers talk and company listens ;-)

If you work with a small company and dedicated dealers you always get involved.  I had a similar relation with a once great company called Sun Microsystem. I happened to be one of their first customers in Sweden when they started up their Swedish operation, knew many of the people and had excellent support. A situation like that make you involved with the company.

Best regards
Erik

Thanks Erik. Perfectly stated. I am close friends with all the dealers from DT and CI and have done a lot of new product testing as well. Jack and I are also considered media since we are owners in GetDPI as well as the owners here are considered media, so product involvement with prototype gear and new released gear we usually get a chance to test and review it which also includes other brands. I personally have bought 5 Phase backs and all there bodies and a good assortment of there glass over the years. My involvement on forums has to be exactly straight talk without any bias its just that simple. I do have preferences like any one else though. Which I freely admit I like Phase gear, always have. I like Nikon and some Leica gear as well. Canon I do not care much for. You want honesty that's all I will ever give. Like it or not whatever I say comes from the hip. I have always been open and forthright on any of my involvements with people. And yes some even advertise now on LL and GetDPI. The LS lenses all three that I have used 55,80 and especially the 110 I liked very much and performed as expected. The Schneider lenses have a very nice look to them.

I don't think that is unappropriate at all. You are assuming everybody knows him.
I do not. I just wanted to know if he was working for Phase because he was
more positive to the 55ls than most people.

Just maybe because I actually owned could be reason enough don't you think or are we all guessing at this stuff. I only talk about what I shoot. Maybe a lesson could be learned here. Lol

Hi Fred,

Could you kindly go rent an IQ160 and LS55mm and please post your findings? 

Thank you,

We have someone who has continually attacked a particular company dismissing anything good that's said about.  Found faults in most every thread begun by people who either sell the equipment or work for companies who sell.  Even still attacks threads where actual users offer their experience.  Attacks have been made against these people mention above even though they are totally transparent; meaning they can be readily found.

Try this - look at the bottom of a post where a signature is and in most cases you'll see a link to that person's website.  Now take a look at the person who's mission it is to attack an industry and most all who work in it.  See anything?  Do a Google. Find anything?  You can try something else - take a look at the threads either started by or contributed by a single person and you'll see the narcissistic attitude displayed.  You either agree or you are against him thus you are his enemy; he fails to recognize other's emotions and feelings as he expects you to go along with his ideas and plans. There's more however if you do just a simple bit of research you'll see.

And to be totally honest and above board.  I count the owner of Capture Integration as a very close friend.  My relationship with Phase One outside of owning several backs and bodies which I paid for is that I entered into a licensing agreement several years ago with them on several landscape images.  I used to own a Leica I loved using other than the inability to print in sizes I normally use.  We also own Canon equipment and drive a Ford Raptor which has been photographed by me for use by my dealer.  No hidden agenda.  I just want to capture landscape images and share what information I can along the way.
