My first K3 Photos Tom G

Hi all
Thank you all for the advice I have had on the forum,


I managed to get out to-day so I was at Danure Harbour, that's in Ayrshire , Scotland near were I live


I tried out the K3 with the 18mm 135mm lens, ( all I have at The moment )

so far so good still need to learn a bit more about F/stops I think that's the right term I was mostly on F 5.6. F 9, F11, I think I get a bit over excited instead of taking my time??


if I.m taken landscapes I should be up at F11 plus is that correct, also when would you use F 22, if anyone could give me a lead on that I would be grateful


anyway here's what I got not brilliant but a start,

Which PP software did you use? There's an awful lot of banding in the sky.

In regards to f-stops, as you appear to already know, larger numbers give you more depth of field (more stuff in "acceptable" focus in front and behind where you focused). There is no magic number to always use, but f8 or higher is often an effective f-stop for landscapes. To get an idea of what focus distance and f-stop will do, I found Online Depth of Field Calculator helpful.

By the way, I think your shots are kind of nice especially if you're just starting out.

well done!
as for the f stops - if you go over F11..F16, some may find that the resulting image has some softness because of the diffraction, but I really can't comment, if it is really an issue, I'll let the more experienced gang voice their opinion on this.

Hi there
Could you explain what you mean banding in the sky.


I do no they are not perfect in any way I use Lightroom 5.4 although I never used any noise reduction i.e. never used the detail slider in lightroom, if that's what you mean,
The sky is a little to blue that's what I see.
Perhaps you could explain banding a little more to me
Thanks very much

Hi Steve Ledger
I see what you mean now, by banding and I do see it in the images, and I have just checked raw images I have saved as Tiff's no banding,
also the same images in jpegs no banding.
But I no what happened it was when I had to convert so I could upload here to the forum, it says no bigger than 900k so the jpegs were 12meg and the raw saved as Tiff's were 137mb saved via lightroom,
Then I select all and export to folder for uploaded to the forum,
but in Lightroom settings export settings for jpeg keep to 900k this is were the banding has happened. ( I think)
So what I would ask is what is the best way to export Photos from Lightroom so I can upload to form, the raw files I have which are saved as Tiff's are 137mb each so if I convert one of these for the forum it is a lot of compression to get it to 900k so I must be doing something wrong,???

only on the images posted here not on the originals so the compression has caused a problem, also save in sRGB format is this correct

sRGB is correct. 900k should be plenty for a jpeg this size. What exact settings did you use in the export dialogue?

Firefox image info says size is 150kB and dimensions 1,203px 800px (scaled to 1,024px 681px). If your image is getting compressed a second time, from ~900 to 150kB this could easily be the result.

Why convert the raw to tiff? Why not just keep the raws as needed on your computer and then as you need them use lightroom to output some jpgs for uploading here. Or even better just use LR's built in upload to Flickr plugin and upload straight to flickr.

Thanks dcBear78
I'm looking into the banding problem with LR, seems if you use a vignetting it can cause problems
see here
Banding in jpeg exports--why??? - Lightroom Forums


Banding on vignetting is not unusual, and in Lightroom's case it's a lack of dithering when converting from 16-bit to 8-bit and from a large colour space to a small one.
Yes regarding flicker I will have to get an account or whatever one does to join


When you use LR do you keep all your photos at 16 bit,
have to look at this the photos I have uploaded here do show banding but not on the originals,
and they can not be more than 900k to upload here If one jpeg is 13meg then that's a lot of compression,
what does flicker allow for uploads I will have to check


Thanks anyway for the advice dc if you can answer any questions above please do,
P.S.
when I bring the raw files into LR they appear to be converted. do you just save as raw, is that what you mean?????

If you upload here the TIF file has to be converted to JPG and "resampled" to 72 DPI.
I don't have Lightroom but I would imagine the procedure is very much the same as in Photoshop, namely you click on "image" then go to "image size" tick the "resample" box and change the resolution from (most likely 300 DPI) to 72 DPI. Next go to "width" in the same window and enter a new value, say 1024 which is acceptable here and save this image as JPG. You are done and ready to upload here.

Greetings

Thanks Schraubstock


Yes there was a few things I done wrong i.e. the DPI was still at 300 instead of 72 yes and I never changed the width
But you do no that there is a problem with banding in LR when you export.
I googled it and it seems it has something to do with the dithering during conversion

Does not appear to have any banding in this photo one of the first from my new K3
The K3 is just a brilliant camera full stop.
I had a look at the Flicker with a view to uploading photos there but you have to have a yahoo Email as far as i can see and I don't want that
please correct me if I'm wrong
