Hi thanks all for the comments and advice. I have seeen a K10d, 4 years old, 27,000 actuations, with an 18-55mm kit lens. Spare batteries, boxed and all accesories. Described as very good condition. He wants £250 cash for it. Anybody care to venture an opinion as to if this is a good, fair deal? From what I can make it it seems to be but I'm not very up on secondhand camera prices. Also if I go to see it anything in particualr I should look out for?

Many thanks
Graham

Hi,

I am thinking aobut gettin gmy daughter a half decent camera for her birthdya. She is 19 a bit ditzy and doing a media course. As aprt fo the course she has doen soem photography and that seems to be what she is enjoying most. I wonder if anyone has any idas about what would be a good starting camera for her, beyond a basic point and shoot. Cost is a factor cos this may be a flash in the pan, I dont think I need to go up to a DSLR just yet so I was thinking of around £200 at tops?

Any recommendations for something that would give her some manual control so she learns about exposure/focus/depth of field etc, but also lets her get snappy learning how to frame, what to look for, the subjectgs she feels comfortable with?

And that would produce reasonalbe prints (although being 19 I am sure she doesnt even think about prionts, she just thows thing sup on the web)

Sorry I'm not clear. Surely in manual mode there is no metering? I use Manual mode mostly, I set the shutter and aperture myself, or I hit the green button to get an auto exposure to use as a starting point. Being in manual mode by defintion implies nothing is being metered., doesnt it?

K7 dead pixels
Posted By grayboy

I have read a couple of threads but wanted to put this on the beginners forum.

I have had my K7 for a couple of months, and I have noticed from time to time some pixels which are presumably dead. They show up red or blue or white. This only seems to happen on long exposures. Tonight I decided to check them out, so I took some shots with the lens cap on. A 30 second exposure showed over 50 dead 'uns. At 1/125 these weren't visible. I did a pixel remap, and on a 30sec exposure they are gone. Which is reassuring, but should an almost brand new camera have so many dead pixels? And what has happened to them? Where'd they go after the pixel remapping?

Question about pixel dimensions/image size etc.

@Mattdm - By optimise do you mean sharpen/curves/levels?

Originally posted by grayboy
Q4 Or should I increase either the pixel dimension or the document size to get a bigger sized print?(From what I read its best to hand the file to the printer who will resize it for me)



How do I make sure I have enough data? Do you mean throw away as little data as possible, so avoid converting to 8bit .tiff or jpeg?


@ Miguel
I thought giclee (point about the buck 25 word duly noted) were ink jet , but superior to standard commercial printing ink jet methods. So If someone gives me two prices for they same print, a cheap inkjet price and a more expensive giclee price - are they working a scam, or will they be using better inks and printing methods?



I seem to be cropping my shots quite a bit, and so it seems that the best thing to do is to crop my photo from the original 3104x4672, and then if I want it printed onto a a sheet of say 12x18 inches, I just increase the canvas size, making sure white is selected as the background colour, and save as a 16bit .tiff. Am I right that this does nothing to the pixels, Photoshop doesn't have to resample or resize anything. Is it better to save as a .tiff or a .psd?



Most are cropped to some degree, some of them are cropped pretty drastically, but i have decided to keep them at 100% crops if I can. But I will have to resize a couple of them to get them larger. In PS7 there is a resize wizard in the Help drop down menu. Am I better to use that? Or is it the same as just resizing by using the selection tool and shift & drag the image handles to size?

I am trying to find someone to do the printing. Do different printers, the machines I mean, have very different qualities, what should I be looking out for? What different sorts of inks are there?






QuoteQuote:

16x24 is close to A2 and will get you about 188ppi. That should work if you are smart about the post processing.



Is that another reference to optimising, ie how much I apply sharpen/curve/levels etc. Or do you mean how I save the file, as a .tiff or .psd. I want to be smart - but how smart is it possible to be, and smart in what way?

I feel like I am probably asking some inane questions - sorry if anyone is getting expasperated, but some of these issues dont seem to make much logical sense. I'm sure they do to those that have a better foundation in all of this, but I feel like i am trying to fly a plane, only ever having flown a kite.

Many thanks to both of yuo for taking the time

live view and focus

I am doing a lot of still life stuff, indoors. I have lights set up, and often i am trying to throw the backgroound out of focus, and keep it dark, while having the objects illuminated. Because I am using the K7 on a tripod, and not usually at eye level, I have got used to using the live view feature. But I cant quite figure out a couple of things.
1 - manually focussing the kit lens isnt very easy in live view, the image is pretty jaggedy and low res when I zoom in and adjusting the focus causes movement in the picture. I have a f1.7 50mm lens as well and focussing is easier, but because of the quality of the picture given by live view it is still hit and miss. I have to check each shot and adjust focuss, take a shot, adjust, readjust and so on until I have the found my focal point. Is this normal, or is there a technique I can employ to help?

2 - There is some kind of gain control going on in Live view, dark parts of the set up cause live view to brighten up, while a lot of light makes the picture darken, which doesnt always help me find focus, is there a way to switch it off?

I am trying to understand the relationship between pixel count, optimum print size, maximum print size, how Photoshop determines the size and a few more related things. I will be exhibiting my photos so I need to know what the best size is going to be for printing. Not that size is everything, but I would like to knwo what my options are. I have looked at some threads and some, OK a lot, of it went over my head so I am asking some specific questions which make sense to me to ask.


So - I am shooting in .dng from a K7. The size in pixels is 4672 x 3104. Because my version of Photoshop, ver 7, cannot read Raw files, I have to open them in the Pentax DCU and then save out them as 16bit Tiff’s. Photoshop automatically opens this as 262.81 x 395.56mm @ 300dpi, with the same number of pixels (almost A3 size). I try to do any Photoshop work in 16bit mode
I am showing soem photos in an exhibition, most of them will be colour. I hope to be able to get at least some of them done as giclee prints. I tend to crop my photos, either modestly or drastically.


Q1 - Is this size,(262.81x395.56mm @300dpi) the optimum size for printing?

Q2 - If I get a print done at A2 - will the photograph look horribly pixelated, or will it be acceptable for an exhibition print? From what I read this should be ok.


Q3 Can I just increase the dpi in the image size to get a better quality print at bigger sizes? (From what I read this doesnt matter - but I dont understand why.)


Q4 Or should I increase either the pixel dimension or the document size to get a bigger sized print?(From what I read its best to hand the file to the printer who will resize it for me)


Q5 Or should I create a new document at A2 size, and then drag the tiff into that document and resize it. Is this increasing the pixel dimensions?

Q3 - In the image size menu, if I increase the pixel dimensions, the document size increases. If I increase the document size the pixel dimensions increases, however - if I increase the dpi, the pixel dimensions change, but not the document size. What is going on here?

Ok that’s enough for now I think. If anyone can explain this in reasonably simple language I would be very grateful.

K7 and CS2
Posted By grayboy

Everything I read suggests that CS2 reads .dng's, out of the box - no need for any updated raw files. But not this version. I am trying to improve my workflow (I started another thread here, ) I snagged a copy from a friend to see if how it works - well so far it doesn't. I can open other files and it sees .nef files from a Nikon D60, but it doesnt recognise .pef's or .dng's.

I would reinstall, but this old laptop is the only computer it will fully install on. I have tried installing on three other computers, but the CS installer installs everything but Photoshop. It looks like it is installing it, but after the installation Photoshop just doesnt exist, there are no no photoshop folders or files anywhere that I can find, weverything else is there, Bridge, Version Cue, Image ready etc etc - everything CS2 except Photoshop. Curious.

So I am reluctant to uninstall jsut in case it decides not to install on this comp as well. very odd.

Ok I'm confused, can Photoshop CS2 with the 3.7 acr update read dng's from the k7?

Or put another way - why wont cs2 with the 3.7 update open my dng's. it displays them as thumbnails, but wont open them. I get the message ...this version of Phtoshop does not supply the services required by this plugin module....

(I only just saw that there is a separate forum for questions like this, but since this thread is on the go already I'll ask the questions here if thats ok)

Thanks for the input, I guess we all find the way that makes sense for ourselves.

Just a couple of comments -

Unless someone knows different I dont think Bridge is available for Photoshop 7 - it was introduced with CS2 i think, and the same with ACR. So for the moment I have to use PDCU to do any initial tweaking.

For the images I am making at the moment I tend to see the DNG's as the starting point, the final image will only come out of various experiments and manipulations in PS. I use PS for things like cloning out, creating layered effects, creating black and white images, etc which I find either easier in PS or not possible in PDCU - which is also pretty slow and clunky - although I am still figuring out how to use it effectively.

I am getting some images ready for an exhibition - any advice on the best format to take to a printer? - the original DNG (if I haven't needed to do any substantial pp)? a psd? or tiff? As I understand it a tiff is lossless, so I dont think a jpeg would be good enough for exhibition purposes. The prints will all be at A4 size.

Thanks

I have only had my camera for about a month and already I am collecting quite a gallery of photographs. I am, I think, reasonably good at weeding out the ones I dont like, or that have technical problems (such as I can discern) or just didn't work for whatever reason. But, given that I am new to this I am erring on the side of caution and inevitably I am keeping more than I need to. With the workflow I am using though I am ending up with triplicates and quadruplicates of the ones I have worked on and want to definitely keep.

My workflow goes something like this.

1) I am shooting RAW, and as I take shots I delete the ones, in camera, that are definitely out of focus, or tests shots.

2) Then I download the days folder to a folder I call DNG's on a portable hard drive.

3) I go through the shots using Irfanview and get rid of the ones that again I can say are defintely not worth keeping. I might end up with four of five similar shots of each subject, with different exposures or focus points or slightly different framing.

4) Then I open up the Pentax Digital Camera Utliity, and I mess with white balance and or exposure, and sometimes sharpen.

5) Then I save that shot as an 8 bit tiff, into a folder I call 'From PDCU'

6) I open the tiff in Photoshop 7, and crop and adjust and layer and mess mess mess.

7) Then I save that as a psd into a folder I call 'From Photoshop'.

8) I also save a tiff to the same folder, for archive.

9) For some of them I save a scaled down jpg so I can upload it to show on this site.

10) If I want to print the shot out I use the tiff.

Any comments on this work flow? Any tips on managing what I can see has the potential for building up into a mountain of photos very quickly?

I know a more recent version of Photoshop would enable me to work on the RAW file, thus cutting out the need for the tiff conversion in step 5, but I dont have the option at the moment of upgrading.

Is it better to use the PDCU to sharpen, or is this better done in Photoshop? Should I sharpen at the end of any pp or should this be the first step in PP?

Thnaks for any words of wisdom.

Click on 'Options' on the toolbar. In the drop down menu click on 'Properties/settings', click on 'JPG/PCD/GIF/'. Select 'Autorotate image according to EXIF info if available'.

See if that works

Nice! Great atmosphere. I know you cant do much about it now but because the lamp post is in focus, and he isn't, it tends to pull your attention away. Maybe you can blur the lamp post? Just a thought. And would i get rid of the little flecks of white on him?? Hmm..

Thanks all - I wondered if the using the window frame to crop to was a bit obvious, but apparently not. Its a shame the car was in the way cos then all the legs might have given it a little bit extra, and I think the little boys shape would have made him a bit more noticeable.

I guess the reflections could have been tamed down with a polarising filter? Is it worth keeping one on the lens when shooting street scenes just in case? Or do they cause other problems, so best only used when you have to?

The colours look good - which is odd because I would have thought the mixed lighting would look wrong, but it works here, and the shapes are very seductive. For me though I would have to straighten it up, the stairs look like they are leaning to the right, and the light is hanging way off vertical. And I might have cropped it, something about the doorway on the right is distracting. Maybe it clashes with the curves? Adam what does CA mean?

Can I ask if you use automode when you take these kind of street shots, or do you set the camera up with a setting based on a general, averaged, meter reading and then hope to be able to sort out any exposure problems later?
