Hi everyone its me again.My last thread was about sharp pictures using my 50-500 Bigma.After some great advice (thanks everyone) Started using f10 at 400mm and all of a sudden sharp,in focus pictures.I am shooting in Raw and was wondering what is the best way to keep the files.
Do I
1)Change the Raw into Tiff,do the necessary tweaks then change to jpeg,keep the Tiff file and bin the Raw file
or
2)Do the necessary tweaks to the Raw file,change to Tiff then to jpeg and keep the Tiff file and bin the Raw file
or
3)tweak the Raw file change to jpeg and keep the Raw file.
Hope I have explained this clearly and once again thaks for the help.I was getting a little frustrated with getting poor pics

Wow thanks everyone. I use photoshop 7 and as someone has already said for wildlife getting close enough not needing to crop is not always possible.I. took some pics of a Bullfinch and did all the necessary edits and then cropped last, and when I looked at the final image ,the lighting looked wrong.Think I will try to crop first.I have been doing all the other edits in the order they are in the program ie top to bottom and sharpening last

Thanks again everyone

Graham

When editing a RAW photo in Photoshop is it best to crop the image before any other editing or do the editing and then crop.

So keep the Bigma and get the K5ii it is then,will put the K10D in part ex (it`s only got 3500 shutter count).I am making a big effort to get out and get some pics and have even rigged up something on the wheelchair using a hide clamp and monopod so I can keep things steady.
Thanks for all the help.

Graham

I could soon have a bit to spend but do not quite know which to do.Should I sell my K10D and buy a K5 and hope it makes my 50-500 Bigma a little better or keep the K10D, sell the Bigma and buy a DA 300 f4.I realise I would be losing 200mm but seeing as how the Bigma is really only sharp at 400 max in good light and apparently the 300 f4 is really sharp so would I get just as good photo`s cropped.I hope I have explained that properly.I have just noticed someone is selling a K 7,would that be a good buy ?

Graham

Thanks for that I will have a good look at them.

Graham

Could anybody give me advice on camera bags please.A couple of years ago I had the Lowerpro Slingshot 200 but since then I have become practically wheelchair bound so need a bag with a flat bottom to sit on my knee which can take a K10D with Bigma attached and room for a few bits and pieces.

Thanks Graham

Thanks again for the great info,I need to get there and take lots of photo`s using various settings and notice the differences.
Thanks once again.

Thank`s for that John.Am I right in thinking that if I focus on a certain point the subject could become more in focus if I change the f stop (in AV mode obviously).

Graham

I am a new to this hobby and so this question may sound a bit daft.Is there a way I can calculate how far a subject is away( bird/wildlife )and also what distance would I expect to get an in focus photo at 400mm on a Bigma.Sorry if it is a daft question.
