Has anyone used this hdr simulate plug in with pse ? if so is it worth getting for a mere novice in hdr.

Many thanks in advance

This Plug-In appears to be an HDR Effect only so not much use if you want to do real HDR.

If you have a high dynamic range scene say 15 stops then a single exposure cannot capture that range. If you take a set of multiple exposures HDR software can produce a High Dynamic Range 32 bit file which captures the scene. The 32 bit file is then tone mapped in the HDR software to map the various tonal values to a suitable 8 or 16 bit file for output. This is necessary because compressing the large dynamic range results in mid tones being rather flat and low contrast. The application of this tone mapping can be crude or sophisticated and can result in over the top surreal effects right through to natural looking images.

This plug-in appear to only offer a crude tone mapping intended to produce an output which looks similar to an over the top surreal look. There are also plenty of other Plug-ins which can do this. It does not create a real HDR image and you need more specialised software for that. If you wish to use a single file and extract the best dynamic range, you need to capture Raw Files and carefully edit in the Raw converter in your pse.

Thanks for the reply Dave - sorry but most of it went over my head - as I say I am a novice, whilst I understand that hdr requires 3 images be it continuous or bracketed or something along those lines then merged to get the optimum result then play with software to alter image, having had a play with this plug in the end results are pretty good.

But for the purists out there they may not be up to scratch.

If anyone has used this plug in I would be interested to hear comments on results in print etc - whilst it is only around 10 or $16 and I have so far liked the results on screen in trial version it would be nice to hear views on this.
