![]() the back to matrix shutter speed and go down same number of shutter speeds.Ĭhristian bloch in his hdri handbook did a test of 1 fstop bracketing vs 2fstop bracketing. if yes, then using shutter speed go up 2-4 shutter speeds 1 fstop worth of shutter speed at a time. put camera into full manual, see if camera still has the matrix fstop and shutter speed. If you put camera into full auto matrix metering, take first shot note fstop and shutter speed. but for your use i would go with 5 or 7 shots each stops apart. Note- my how to is using a 1 bracket setup for hdr. If you are interested in hdri technique, i have a how to in my attached reply. The above 2 methods rely on the software to do the work. this requires some photoshop expertise on your part. THEN combine the 2 images with photoshop. The only other method of doing what you want to do is to take 2 shots one exposed for the moon, and a second shot exposed for the water and surroundings. they each will appear correctly BUT to each other they will not be right. the draw back is that though the image is correctly exposed you will loose the relationship between the adjoining areas of different brightness. instead your software simply picks out the correctly exposed parts of each of your 5 images and combines them into 1 image. this can be seen and printed normally.Įxposure blending is very similar to hdr but the tonemapping step is deleted. using the software you then convert this image via a process called tonemapping to an ordinary image called ldr(low dynamic range). this cannot be seen on your monitor but it has a huge DR. ![]() to make this image you then use hdr software like photomatrix or dynamic photo hdr. after you take the 5 shiots they are then combined in a hdr image. remember bracket with shutter speed ONLY. i would guess that 5 shots might work, each 2 fstops from the adjoining shot. how many shoits depends on how big the dynamic range that you are trying to cover. Hdri means that you are atking a center matrix or average metered shots then bracketing with shgutter speed only so many shots on each side of the center shot. if anything moves it will show up as movement between the different shots, as it takes time to shot the 3 or more shots needed for either technique. and that is they are really made for scenes that have no movement. HIGH DYNAMIC RANGE IMAGING or EXPOSURE BLENDING. This means that a single shot of yopur scene is not going to cover the DR no matter how many shots you take. if the dynaimic range of the scene you trying to shoot is more than the above then you are going to blowout one end or the other, the lights or the darks. for jpoeg it is about 6stops, for raw about 7-9stops(depending on which camera). the dynamic range of the camera's digital sensor is only so much.
