PHOTOGRAPHIC THREADS: camera queries, any photo tech stuff!

[David Nicholson]

I must admit to no photographic knowledge whatsoever and I must be thick to boot, but I only understand around one word in every ten on these pages

[David Pilling]

There is a good article on focus stacking here:

describes various pieces of software, some of which are free, here:

Maggi: I used Google to find the article.

I only have a pocket camera which is OK for most things, but I find it really hard to get good focused pictures of bright yellow flowers . Particularly upsetting as some of these are to my mind the most lovely. Any tips?

[David Nicholson]

Really haven't a clue Ron but I do wonder if my grey background helps on mine which really aren't the best in any case.

Seems I can get the little square thing to say its focused David, but then when I look at the picture I took it isn't . I think because I'm using a basic camera its getting fooled by the uniformity of the yellow colour and getting no depth. But then 

[David Nicholson]

Ron, does your camera allow you to press your shutter button down half way to get your subject in focus, and then to continue pressing down when you're satisfied? I talk a lot of cobblers, don't understand it myself, perhaps one of the technocrats will come to the rescue

It does David, but it doesnt seem to be able to differentiate between subtle differences in yellow! As a colour scientist I could understand if this was in the grey area, or it was been messed up by red, as our eyes are, but no, yellow is my problem . And its a Nikon

[David Nicholson]

I have awful problems with reds which come out as horrendous pinks.

Ron are you using the macro icon for close shots? Do you know how close your camera allows you to get? What camera are you using?

[Lina Hesseling]

Does anyone have an idea about the quality of the Canon Power Shot SX 40 HS?

I am thinking off buying this one. It has 35 x optical zoom and adjustable display.

I would appreciate your comments.

Lina.

Hi Mark,
Its only a Nikon S3100, and it doesnt seem to want me to be closer than about 8". Which is OK. For everything else. I simple crop and sort it. But with yellows... no good! Maybe just cheap!

"Macro
 
Close up shots are not a strong point of this camera. You will need to be around 10cm away from your subject before the Coolpix S3100 is able to focus. That is more than three times the distance some cameras in this category can manage. As long as you are at that distance the camera is able to produce an impressive level of detail, but without cropping your shots will look a lot more distant than with most digital camera macro shots."

Thank you so much Mark for bothering to go into this detail on my behalf!
I really appreciate it. Will do my best from 10 cm. Thank you.
