Hi, Would be interested in any views S100FS owners have of using the Dynamic Range Bracketing option.

Although not a fan of HDR I can get reasonable results with the S100fs Best results are on a calm day as there is a small amount of lag between shots when using RAW .

A tripod is a must as is a cable release for blur free images. Also I think doing the HDR should be combined manually as stacked shots in photoshop and not use the software's auto feature for better results. You still have to be careful to get the setting right before you shoot. It is easy to get the positive exposure too high.

For me personally it's too much hassle and too easy to over do but the camera is capable of good results.

Hi Chris,Another option to using Auto Bracketing is take a single RAW shot, then use Photoshop or similar to produce the over/under exposed shots required.  This will eliminate movement of clouds, tree branches ect.  Also you don't need to use a tripod.Have a look in my gallery for HDR using the single RAW technique with a S100sf.

Much appreciate replies from Ray, T-mex and Mike.   The thing you all have in common is that you suggest using  the RAW option on my S100FS , which todate I have not used.  

Since you all use it, it must be the next thing I force myself to try, although I will then have to consider software to process it.   Any preferences ?   Have you used the Fuji supplied product ?

Back to HDR, if you have used the S100FS dynamic range option, have you also used the bracketing option, also available on the menu.   I know the HDR option appears to switch the range between ISO 100, 200 and 400, and as Mike points out, generates an additional amount of unwanted noise.  With the 3 shot bracketing option, you can chane the aperture to max 1 fstop between shots.  Which would provide the greatest dynamic range option ?

You should be able to bracket a full stop either side. ISO values are still to do more with available light rather than bracketing itself. Use the ISO value you would normally use for the light and the shutter speed / aperture you want to use. RAW allows you to fine tune each image more if you wish before or during processing your HDR image depending on program and method used. The quality of a RAW file from a jpg on a fuji camera is quite large so shooting in RAW in general will give you better results though a bit of post sharpening may need to be added. The dynamic range comes from the difference in exposure between the three shots. Getting an HDR right is an art in itself and probably better answered by a member other than myself as I've only dabbled in this out of curiosity.

I use Photoshop but you could use the free download of S7RAW to adjust Fuji RAW files ready for HDR but I'm not sure you can do HDR in S7RAW itself.

-2ev so it will be dark 0ev so its still under exposed dark .+2 should be lighter more to the original you would like .just a touch lighter ..all in raw format .if you do them in jpeg .you gonna loose alot of info needed .and by the time you have finished it wont be anywhere near as good as raw ...off you go in your photo shop .i dont no about the s100 but this is the way i dot it .well when i do .have not done any for some time now .but those are the normal setting i would use with any cam that as that option .when i get my new lens .i`m going to do some for the gallery .i`m a little tripod shy lol. but its essensual to use one .and a wireless remote if its capable of using one.

Ray, Thanks for the reply and I will google S7RAW to see about downloading.

James, I tried to go to the URL you provided

http://www.myfinepix.co.uk/competition/entry/77329  but it returns an error and you cannot get to it.

my entry this month: http://www.myfinepix.co.uk/competition/entry/85824

Mike,  I am busy perusing your reply, lots of information to take in, work flow information really useful, and helpful advice about various HDR software packages.

Many thanks to all.

Looks like I will have to start using RAW and acquire new software.   That means acquiring more knowledge and spending more time out and about taking photographs, which I am quite happy with, but I also have to worry about 'her indoors', the garden and all the outstanding decorating jobs I have to do.  Any offers to help with the household chores ?

I haven't tried it in earnest but the following link may be of interest if you use The GIMP:

(Both The GIMP and the exposure blend script are free to use)
