Hello everyone. I need help with Photoshop's "merge to HDR feature I will explain what I do, I take a shot in RAW, and convert it to jpg in adobe lightroom. I also change the exposure, so that I have 5 differente xposures, 1 stop difference each. (the correct shot is at the middle) I then open the "merge to HDR " feature in photoshop, but when i choose the files and click "ok" it gives me this message "there is not enough dynamic range in these photos to construct a useful HDR image" Now I will disagree with what it says. Anyones knows whats wrong?

you need to take several DIFFERENT exposures, with your camera
meter the scene, and adjust the shutter speed in 1 stop increments (lets say the scene is 1/60, you need to take shots at 1/30, 1/15 and 1/125, 1/240) in CAMERA do not adjust the aperture, the ISO or the focus, and especially not the position of the camera
then, take the images from the HDR and merge them in photoshop (no need to process RAWs).
after it does the process, you will get an image in 32bit (which you cannot display on your screen) you need to downsample it to 8 or 16bit, which involves playing around with curves etc (i'll let someone else explain the pro's and cons of each method, its been a while since i played around with HDR)
The reason that its saying that there isnt enough dynamic range is because changing the "exposure" of the same file does not magically create dynamic range that wasnt initially there.

Photoshop Artistic Filters: Disguising poor Photography since 1990.
The problem is that technically you are not using 5 different exposures, it's one exposure that's been adjusted using software. Photoshop uses the exif data, which will be the same for each image, hence the message. You would probably need to remove the exif data from the images, then manually input the EV spacing.
You can either take different exposures, or do it from one RAW file... I think Photomatix will do a better job for you, as they have a dedicated single file conversion part. You can download a trial free to see if you like it.
When you save them as JPEGs, use the Save for Web option, and it will strip the EXIF data from the file so Merge to HDR won't complain. Either that, or don't bother. HDR is overrated, and will look even worse if it's all done from the same RAW file rather than from bracketed exposures.
