Oh crap, it ain't working. It worked for than one shot but not for others. I've traced the culprit to the step where you go from Lightroom into CS6, the default export seems to be Prophoto. Then my source was Prophoto in CS6 and my destination CMYK US hence totally messed up colours.
Ah ! Got it ! I think.. It's locked as Prophoto from it's Lightroom export so rather than 'save as' in CS6 I save in 'save for web' as a jpeg with 'convert to sRGB' ticked. This gives me a good file size and so far.....NO GREEN.

Thank you all so much for your help guys, it does look like not having my destination space set to sRGB is the problem. Why it was at something else I do not know.
But as a test here's the clients upload to MM Where Professional Models Meet Model Photographers - ModelMayhem
And here's mine just now after opening the jpeg I've kept on my drive in CS6 then saving it back in sRGB.http://www.modelmayhem.com/portfolio/pic/32369838


Looks fixed to me, now how many clients have I got to write to now !

I think I may have found the issue as mentioned my C-meier, as it's just images that have been run through CS6 I presume that's where the problem is created. So I found this: Why Your Photos May Look Bad on the Web | Pioneer Woman Photography | Ree Drummond

Looked at my colour space settings and found that in CS6 (edit-convert to profile) that my source space was sRGB but my destination space was CMYK Us Web Coated. I HOPE that's the solution so I've changed destination to sRGB to match the source. Just got to try and recreate the issue then see it fixed !

Really confused by this, a good number of images I'm producing for clients recently take on a very green tone and are drained of other colours once they get posted online. I shoot with a K5 and the limiteds and deliver my images in full resolution. My impression is that this occurs after resizing, and oddly on some images it's just the thumbnail and when you click to open it corrects itself.
Here's an example of fully green: Where Professional Models Meet Model Photographers - ModelMayhem
And if you look at her full portfolio, Where Professional Models Meet Model Photographers - ModelMayhem
you will see a few green thumbnails, but if you click on image 3 along the top the colours pop back when it enlarges.

My other feeling is that this only happens to images that have been put through some processes in CS6, but they are fine on my monitor.
Another example is here, if I search in Google images "my name" and "the client" I worked for the thumbnails along the top look awful, but click through to the site and it corrects. However, she posted the same shots to Facebook and one of them remains green.

Woah ! Or I could just not bother with fixing it ! Just found this on a general search of children's studio photography and (not being critical naturally) this photographer has just rolled with it. Is it me or does the problem gradually fade as you go from the youngest to the eldest ? Scroll through to image 2 for the best example.

Okay, again all sterling advice from everyone but I'm going to reiterate the following: I'm not really looking for a fix in post, I can do that. The fix has to be extremely quick so local brush adjustments et al just won't cut it. I globally tweak WB, saturation on orange and yellow channels followed by luminance for the same colours and that gets me somewhere close to what I'm after on the face but can drain the rest of the frame. BUT timings wise just about allows me to do this batch badjustment

What I need is to avoid the phenomenon IN THE STUDIO. And it is a phenomenon, the kids do not look like this in real life, it is not a quirk of lightroom's colour space, the yellow patches appear the second the shot is captured on my Pentax lcd screen.
My bet is that where the skin is thin the lights are 'burning through' and picking up developing cartilage (it's nose and ears) and for reasons beyond me this manifests as yellow.

And I think it's a combination of sensor, lenses,lights and a narrow age range otherwise this would be a common issue in the industry. There is chatter about this for other brands of camera system but like no more than 3-4 threads. I just seem to have hit on the magic formula to create this weird effect.

So, all the advice on post fixes is honestly great but I need to not create the problem in the fist instance.

And just so we're clear, my 7 models from two days ago produced 700 shots I had to deliver today. That's what I'm getting paid to do and the client has a business process they adhere to and I'm fully prepared to do my bit.
I can re-negotiate with them anytime but I'd bet I'm the first guy they've used who's gonna ask for extra time or a change in arrangements cause 'these kids have gone yellow'.

My approach to virtually all photography is get the shot close to perfect when you press the shutter. And beautiful kids, in a pro studio on white colorama with a shooter who knows what he needs to know the goods should be giving me that.

JJJ, oh it's not the perfect brief but it is a brief I've accepted. Client (there is only one, it's an agency) requires 100 untouched jpegs within 48 hours of the studio shoots. I shoot in raw then convert via lightroom in case of any major issues. My hour with each atendee generates about 160 shots then I edit this down to the 100, the client requires no re-touch on my part and I then deliver the 100 x however many subjects I shot. It is as mentioned before entirely normal to get on average 3 subjects with yellowing issues, just to be clear here they do not have them in real life - only once captured by the camera, hence 300 images needing fixing being quite common.

Yes it's a mammoth task and yes it means detailed and individual re-touching is totally out of the question. It's not how I would normally work but as a photographers we can only change clients expectations so much, I'm more than happy to accept a challenge, work in a different way and fulfill what on the face of it (pardon the pun) is a pretty simple if labour intensive brief. I know that the speed of turnaround has an effect on the end product and the client understands this, my job is to give the best images possible within the constraints of the prescribed request.

And Maxfield thank you so much for your detailed run through, it'll be a great help and point of reference for a number of future shoots no doubt and you clearly know your stuff. Just for this one scenario though what I'm searching for is a technique that nullifies the yellowing effect or reduces it IN the studio, not in post. But I think I'm looking for a unicorn on the moon here aren't I......

Hi JJJ, thank you very much for the feedback and corrected image, I'm impressed with your efforts. It's pretty close to what I can achieve in LR but of course you were able to fix just the face leaving saturation as it was in the rest of the frame. Hence overall your version looks a bit better than my fixed shot.I sadly don't have the time on this job to fix every shot individually. And therein lies the problem, I don't want to fix this, I want to avoid it.

I can be shooting 8 subjects in 8 hours and my paying client requires 100 jpegs delivered in 48 hours of each person. So lets say I get 3 toddlers in the session, that's 300 shots to locally fix !!!! Just can't be done ergo I have a massive need to get the shot spot on at the first click, though I think I'm going to struggle with that quest.

So I shoot a lot of children and recently just by chance they seem to be getting younger. And I'm having a major localised colour issue with toddlers that I simply can't control. As you can see in the attached shot the child has a distinct yellowing around the nose, this also occurs on ears and necks. It is happening on nearly every child I shoot between the ages of 1-3. 4 year olds and adults and there is no problem.

I can find minimal but identical problems discussed online and most feedback is concerned with how to fix in post. Some have suggested it's an initial over exposure and one or two refer to it being the reaction of young developing skin and tissue under powerful studio lights, you are essentially revealing the fatty bits under the skin. I've tried a number of white balance controls during the session including custom with a grey card but to no avail. In lightroom I can tweak WB then reduce orange and yellow saturation then boost the same colours in luminance. Combined this reduces the issue considerably but naturally has an impact on the rest of the frame. It just goes a bit wishy washy.

The turnaround for the client means local adjustments in Photoshop is out so other than my global fix in LR is there anything anyone can think of that can help me avoid this during the actual shoot ?

I thought it may have been a cast from the light bouncing off the floor but I have a shot of the same child being held aloft with lights at adult height, his mum and dad look spot on but this poor chap looks like he needs a doctor. I'm honestly baffled.

Basically I need to get the shot close to perfect first time but as you can see I'm way off that.

Well I shot today and I don't need to tell you how tough it was. Got some FABULOUS images though but I only had an hour to do the whole lot in so probably missed as many. The lenses paired with that sensor are outstanding and I look forward to owning them for many years. But I got 9 full 8 hour day shoots in the diary and growing and I don't think I can risk it. Anyway, from very early this morning to show what stunning work it can do......

Fa43, f4, 1/80, iso 100. cheap Yongnuos shot through even cheaper umbrellas on even cheaper stands. Light costs very little.

Right so a whole day in the studio, settings tweaked as suggested to give the K5 a chance to work properly and.......... no. No good.Less troublesome this time and mostly with the 77 but it's clearly nothing to do with light or contrast as has been said and as I suspected. I guess I got a faulty shutter button.Not the end of the world but I got to post it to the ONLY Pentax service centre in the Uk then wait.... Canon have a place in London I can walk in to and their turnaround sounds much quicker.

There ain't nothing worse than a tool you do not have confidence in.

I'm going to keep my k5's and lenses and always carry a set as my back up but I think I'm accepting what I've known for some time, These tools aren't right for the job I'm lucky enough to have. Pentax are alright, Canon are alright. I just need the better, easier to fix, best service supported and consistent performance version of alright. I don't think the k5 is that camera, not 2000 shots a day over a long period anyway.

I shall keep it as my Sunday best.

I have tried the rear AF button yes but without any improvement. Main button might need a clean, I guess I'm up around 40,000 fires and it started about 5000 shots ago. I'm in the studio next week so I'm going to take both bodies, 43 om the current one, 77 on the old. Keep the old on standard set up but turn off sr and switch focus priority to shutter on the new one and see what gives.

Sad truth is though that with the rate of work I'm very fortunate enough to have in the diary although I LOVE my lenses I'm coming round to thinking the K5 body and more importantly the service support no longer match my rapidly evolving shooting.
Even if there is a work around for this issue it's opened my eyes that the system is coming up just a little short. No client, model, company or anyone I've shot for have ever asked me what camera I shoot with cause naturally they don't care. But they do care about image quality and getting the job done.

I can guarantee the first but I'm starting to get nervous about the second.

Oh Pentax ! Bring out an FF and decent Pro support just for little old me by next week, please !!!!

Sorry to resurrect this thread but the problem is just getting silly now, I think it's time for a trip to the service centre. More of that in a bit.

Just to re-iterate I'm pretty confident I know my way around the body and this is now happening on the three lenses I use most so it's not an issue with them. And it's happening both on location in AV and in the studio on manual
. The only thing I think has been constant with this issue is fading light but I haven't kept a diary. My outside failures were late winter afternoon (but nowhere near dark) and indoors it's once natural light has started to fade in the studio. But I have modelling lights and of course the green light of focus assist for extreme moments.

Yesterday being a perfect example: In the studio using high end lights and triggers. Full manual, iso 100, F8, 1/125, AF.S, centre point focusing, S.R on.
Latest firmware and the only things turned on from the factory default are expanded sensitivity, permit aperture ring and micro focus adjust.

Using an FA 43 everything starts out fine but after about an hour or 2 the problem starts up. Locks focus with a half press, confirms with the hexagon, confirms S.R then nothing. I press and it's as if the memory card is full. It seems to me that if you REALLY press hard you can get a shutter release about a second later but that's no use when shooting moving subjects. Sometimes when it refuses to fire you will also get focus hunt AFTER focus confirmation, minimal whirring back and forth then it will fire. Fine if I was in continuous focus but I'm not !

I then had a break in my schedule of over 2 hours so left the camera off, 20 shots on a fresh card so hoped for perfect responses when I started up again. No such luck, straight away It stiffed up. And although I can't say 100% it only happens shooting people, but then that's pretty much all I shoot. I know they move and so do I but I'm on AF.S so it shouldn't matter.


Hands up I never saw the above reply so I will try no S.R but that's part of the reason I chose the Pentax system. Seems daft to have to turn off a important feature to make the thing work.

At that's the main issue, it working. I am currently getting a frequent amount of work and where as the K5 and the limiteds deliver totally fantastic images I simply can't have a camera not releasing it's shutter. Then to go to repair means I'll lose work and I don't just mean the odd job but ongoing arrangements. I have a back up body but (I won't bore you with the details) it only functions in manual. Great for the studio but then I'm operating for however long on one body and that is a definite risk knowing my back up body's history.

So I'm kinda stuck, I can muddle on but suspect the shutter release is gonna fail mid shoot somewhere. And this isn't a slight against Pentax and jumping system has never really seemed a big thing for me, I can wait for FF. But both Nikon and Canon have Pro service arrangements, I know I'd have a repair or a loan between shoots.

Anyway, I'm going on a bit here so my main reason for starting this thread again is to see if there is anyone else reading who knows if there's an in camera fix or a simple explanation I'm missing so I can avoid a trip to Pentax.

Rob.

So I'm moving into speedlight photography and have a couple of indoor hotel room/bar gigs coming up. My question is do I really need to gel my flash heads to match the lighting in the space or do what I would normally do ? Namely take an 18% grey card shot, set white balance, then tweak the WB of the RAW in post if it needed it.

I'm all for getting the shot right first time but I'm way off understanding what gel to use for what could be a mix of bulbs and light sources so am I missing something here, can I not just fix in post as normal ?

Somewhere within this blog Google Translate lies the serial number explanation.

the guy has two lenses next to each other, one low serial one high. The 'lead' lens has a reddish purple tinge to the glass and the newer one is green. He states that the 3 runs of slightly different lens start with the batch 0000001 to 16000.

But yes, the real early ones had a brown pouch and Pentax was inset with black on the lens cap embossing. Sadly the link isn't for the page I've seen.

And can I find that exact post again ?
No !!!!

But who cares when it can do this ? F2.2. 1/25th iso 400 and handheld.

And if the internet is to be believed it's the first incarnation of the lens as it's from the 0 to 16000 serial number production run. Suggesting that these have lead in the glass or the coatings (it certainly has a purple sheen to the front element as oppose to a green tint) before Pentax were required to stop.
But of course as I don't have another FA43 that's largely irrelevant so I shall just go out and shoot.
Still, I reckon I got myself a bargain.

Echoing the comment above, you have sharpness and clarity, just learn what tweaks you can do in camera and out to deliver the colours you see or want.

The Pentax is giving you a great platform to create great photographs.
Unless of course the top picture is the K110d !!!

DA* 50 back focus - ways to resolve?
Posted By London Rob
Replies: 4
Views: 990
MY understanding is that debug mode in the easily searchable pktether allows you to do this: You can access what seems to be an engineer only menu, one of these governs af adjust and within this there is a similar -/+ adjust to the K5's regular focus tweaking feature. BUT this has increments of 10 so goes up to 100 in 10 steps. MY understanding is that 10 in debug=1 in regular. It is a global body adjustment and does not recognise lenses.

So as I needed more than +10 in regular, I adjust debug to +50 (+5 in real money) and set. This appears based on testing and the opinion of many others to re-assign the zero point in regular to a permanent +5. It doesn't show as this it still reads 0 but my lens now comes to life at +7 (+12), all my other lenses also hit their sweet spots at a different figure in relation to my 5 step shift.

you have to watch if any of you lenses needed big minus changes, as you now have in the real world nothing more than -5 available as you have shifted the whole thing 5 steps to the right.

Phew ! I think I'm right.

Hi there, not sure whether you mean the da*16-50 or the da*55 or the new plastic da 50. I don't think there is a straight da*50.
Either way that probably doesn't matter. What does matter is whether you are mounting it on your k5 (you don't say) or the k200. I know with the K5 that you can download a great programme called pktether which amongst other things allows you a broader range of front a back focus adjustment as it gives you the ability to enter 'debug mode'. And just for the sake of time I'm going to presume you haven't used pktether to solve the issue but forgive me if you have.

My fa77 needed more than +10 so I use debug mode to shift the middle zero point of fine focus adjust to a new value of +5. Essentially my scale now goes -5 to +15 and my 77 sits pretty at +12 with all my other lenses in the low pluses.
There's more to explain about debug than just that but there's plenty of info out there on how to use it and it's very simple.

Thank you both for your replies. I understand the focus priority point but what I don't get is this. I can (using focus-prority in AF.S options) lock on to something at say 2 feet away then turn around to point at infinity and still be allowed to shoot. It will be out of focus but it will do it. So I don't understand why it will without warning stop me doing so. Surely it should NEVER fire if focus has been lost. If I concede that my subject has moved slightly I've always still been able to shoot, it will just not be a keeper. It happens on my FA50, DA35 Limited and FA77, none of which are SDM. Though the problems discussed above do sound identical to mine.

To reiterate, I'm on single point AF, AF.S set to focus-priority, I shoot all day with no hitches then it just starts locking focus as normal but giving me no fire on full press till I focus away then return. Even then it still messes up. One thing that was true of yesterdays issue was that my memory card was 95% full. But it can't be that surely ?

On my second k5 now so I'm very used to their performance and nuances. Recently my 6 month old second body has started to show (albeit infrequently) and odd problem.
Irrespective of lens mounted I can get focus confirmation using AF-S from a half press but then full press doesn't fire. Half press again and it hunts a bit then might fire but it's very hit and miss.

This tends to be late on in a shoot but whether in the studio or outdoors there's clearly enough ambient light. This is always shots of people or models in AV and although not totally static their movement or mine surely can't stop it from firing.
I have been through all menus and all I have activated is focus fine adjust, everything else is factory spec. Latest firmware, everything in tip top condition.

Thoughts ?
