THere is some user feedback on that flash on flickr, for the money it certainly isn't a bad flash there is only some inconstancy with the flash power compared to the controls.

The difference between 1/2 and full for example is only very little and not what it should be.

Thank you Tim, it seems it's settled then for a part.

About the trolling and the part you're highlighting and the second part "Trolls are motivated by a desire for attention by people and can't or won't acquire it in a productive manner." if you've for me an article to a internet site that explains it, I would already be happy and I don't deliberate make it lengthy and actually I would rather have it straight to the point, far less reading for me.
So even with your description about trolling I can't fully find myself with some key parts in that.

Back to the topic now.
I believe the iPhone 4 is out in the UK, have some already have experience with the phone?

Thank you Doug, lets hope the education systems change in your favour.

I don't have many debts are regular things I need to pay so it's still easy for me luckily

The higher degree here isn't confirm by the rules of the government for education.
You need to have certain subjects and it must be teach in a certain way I believe to be under it so the study cost are for you fully. They are trying to get their papers though but it might take another year.

Indeed you don't need a degree, photograph isn't a protect occupation so everyone can call themselves one.
For now for you it's good but if you've your paper it's not.

What do you plan to do with your photography commercially now, portrait, journalism?

No there is hardly any difference so don't worry.
With the K10D it actually stop firing the flash when you set the shutterspeed at 1/200 or above, don't know if that's true with the K-X but if you can get your flash to fire that might be the problem.

I'm sure you're right about the Ricoh camera, I've never hold one so can't share any experience about that.
The flash indeed isn't dumb but it's dumb for the Pentax since they don't speak the same language, I hope the ready signal is the same with both

About TTL, Pentax only supported that with the ist DSLR cameras (and some film) but with the current DSLR and a bit older only P-TTL works. So your hopes to get a TTL flash working on the K-X is non.

Yes you're right was looking at my camera and didn't came up in me the K-X might not have it.

Yes you are quite right, found this.
The higher the sensor’s sensitivity is, so the efficiency of the flash will increase. Doubling the ISO will increase the GN by 1.4 and after ISO 100 will double the GN.


No problem if you want to know more there are some good articles on the web that can help you and even video clips.

Manual does sound taunting but you've instant feedback how your photos are with the K-X so if you're trying some still life's at home just take you time and experiment with the flash on manual.

Was expecting voetbal

The photo is very nice, the dof is off course the best feature with the colours.
It's great the flower has some yellow points to really hold the eye.

Indeed congratulations, hopefully it runs.
What kind of study is it and how long does it run?

Here the lower grade entry is already full, so they actually start it 4 times a year if they can, that does sound a lot but they don't make classes bigger then 16 students.
The Higher grade doesn't run that super so I still have a shot on that, it's bachelor grade I believe.

Both studies take 4 years to complete, for the high grade it's once a week to school and with the lower grade 3 times.

Just saw your comment.
The price for the lower is hard to say since you can get help from the goverment to finance it and there are different prices and systems for it, to complicated.
the higher grade is easier, it cost € 3.692 per year.

Do you mind if I give you a link rather then explain it?
http://www.cambridgeincolour.com/tutorials/sRGB-AdobeRGB1998.htm

Very short summary.
Adobe RGB has a greater colour range then sRGB, that's good you would think.
The problem is that JPG has 8bit colour space so the amount of colour steps remains the same. That means the steps of the greater colour space of adobe RGB are bigger then the ones with sRGB so the graduation, flow from one colour to the next is better then.

The only times you can see the bigger colour space of Adobe RGB is with certain prints and printers and special expensive monitors like Eizo.
If you've a normal screen or show them on the web you can only see sRGB.

So if you hardly print any photos or have the printer for it, sRGB might be a better choice for you.

I actually doubt you can get the V4 on ebay since they are mostly sold in stores.

Here is the official site
V4 link
V2 link

The thing to watch out for with the cheap ones are miss-fires, that happen when the receiver doesn't see the signal to fire and doesn't fire the flash.
If you get the more expensive ones you get more range and better build quality and other features but those aren't really needed.

I've the Cactus V4 and they have never miss-fired once with me and some members here have the V2 and i haven't hear them complain about it.

The only problem with the V4 is that the Pentax AF540 doesn't like it, the flash doesn't sync well with the receiver.
It's just that combination because in the store we tried various off flashes without any problems.

Actually went to an open day and asked that and I'm now waiting on the date I can come over to show my portfolio.

Well I didn't actually asked what they were expecting but what they wanted to see; the answer was quite short. They wanted to see variation in the type of photos so macro, landscapes, portrait, ect. I specifically asked if they wanted to see series, he said one or two small series might be nice but they rather see variation.

I was applying for a general study, you can also do specialisation and then surely there is no other way then show series.

Maybe not really what you asked but it might help.

HS is a special mode, it actually fires multiple flashes very fast continuously to evenly lit the whole sensor.
I believe it even times the flashes according to the shutters and how fast they move.

What I meant was is that 1/180th isn't a natural shutterspeed for the camera to come on since it use 1/3th of stops. Just set you camera on Tv or manual, you get 125 - 160 - 200, there is no way you can set it on 180.
So the camera need to know a flash is on the camera to make it stop there. Sadly I believe you've a dumb flash which doesn't tell anything against the camera so it won't stop.
The only way to get it then on 1/180 is the use the X-sync mode, that's the flash sync and set the shutter permanently on 1/180th.
It's the red X on the same dial where you find Av & Tv, ect.

Maybe if you get the ready signal working it might actually stop on 180.

What do you mean with the guidenumber and speed?
If you mean shutter speed then actually it doesn't have any effect at all on the guide number. If you mean ISO speed then a doubling in the ISO/ASA means a doubling in the guidenumber.

You use the guide number to know what kind of aperture, ISO speed and/or flash power you need to use at a given flash distance.

Shutter speeds controls the amount off ambient light in your photo and it does not effect the flash power or guide number because the flash duration is 1/6400th of a second or something like that at least it's extremely fast, so you always get the full flash in your photo.

If I'm not clear enough please say so
