Choose 32 bit from the Mode dropdown menu if it is in 8 or 16 bit mode. Click the Tone in ACR button. THe image will now open in Camera Raw. You can perform all the usual adjustments that you would do in Camera Raw, with the luxury of working on a 32 bit HDR image which has much more availible detail in the highlights and shadows. Take advantage of the shadow and highlight sliders. See ACR Tutorial here. The image will still be in bit mode.
If you want to do further tonemapping, you can jump back to step 5 of this tutorial and work on your photo with the advanced tone mapping tools in Photoshop. Yes, you can double tone map an image with great results. If you are happy with the current results and finished working on the tonal adjustments of the image, you just need to convert to 8 or 16 bit and finish off like you noramally would on a regular LDR Low Dynamic Range image.
The tone mapping options will pop up, to keep the appearance exactly as it was in Camera Raw, choose Exposure and Gamma as the Method. Set the Exposure to 0 and the gamma to 1. Click ok and your image is done. I know there is a lot to it, my 4. Merge to HDR as mentioned earlier in this tutorial. Use the adjustments as you would normally, but enjoy a lot more control and larger range of tones than before.
If your desiring a more surreal result there are different plug-ins that you can use. My favorite is Photomatix pro from HDRsoft. You can just get the tone mapping plug in for Photoshop which works great. Using photomatix tone mapping plugin allows you to get highly detailed textures in your photographs.
You merge in Photoshop as shown in this tutorial. Convert and save as normal. Here you can see comparisons between a single image, subtle Photoshop HDR and a radical Photomatix effect Whatever result your after, hopefully this tutorial has helped demystify the HDR process. Here are a few more examples of my HDR photography. Check out my Gallery for more. If you are ready for deeper learning see my Premium training on HDR as well as Photoshop and Lightroom which cover these topics in greater detail for those of you who really want to master the subject.

Post processing work after taking any photo is always a difficult task to do. But yes the professionals are not worried about this at any point. If the shots can be made perfect before taking the images that would be more worthy for me as I am not so much good at photoshop. Hello, Now a days photography tutorials is very important things for all.
I have an issue with my cs4 that I was hoping someone could help me with. This was a good suggestion that you put up here…dude….. Is this being maintained or updated anymore? The more you know, the more you know.. Now, remember that not all Photoshop users are Photographers. I am really impressed to this tutorial. Thank you. Absolutely love your tutorials. Thanks so much.
Is there a way to download your tutorials so I can put them on my desktop for easy reference? Occasionally I release some on PDF, if you are on the mailing list, you will receive them when I send them out. I have a problem with my CS4 with which I was hoping someone could help me. I automated: merge hdr for a while, but recently when I clicked ok, it loads for a few seconds and then creates a white background labeled hdr until it runs dry and leads me to the next edit page. Your tutorial is amazing.
A complete newbie in HDR photography also do well, if they follow this guide step by step. To preserve the original image, create a copy with the Save As command.
Edit menu commands. File Formats. Image commands. Pixel Aspect Ratio. Some tools work with supported blend modes only. However, only a bpc file can store all the HDR image data. HDR merging works best when photos are optimized for the process. For recommendations, see Take photos for HDR images. Skip to step 5. Choose 32 Bit if you want the merged image to store the entire dynamic range of the HDR image.
Move the slider below the histogram to adjust the white point preview of the merged image. Moving the slider adjusts the image preview only; all HDR image data remains in the merged file. The preview adjustment is stored in the HDR file and applied whenever you open the file in Photoshop. If you are using one of the above, see The Camera Raw Filter no longer works with bit files to view workarounds for this issue.
Local Adaptation. Radius specifies the size of the local brightness regions. Tone and Detail. Dynamic range is maximized at a Gamma setting of 1. Exposure values reflect f-stops. Drag the Detail slider to adjust sharpness and the Shadow and Highlight sliders to brighten or darken these regions.
Vibrance adjusts the intensity of subtle colors, while minimizing clipping of highly saturated colors. Toning Curve. Displays an adjustable curve over a histogram showing luminance values in the original, bit HDR image. By default, the Toning Curve and Histogram limit and equalize your changes from point to point.
To remove the limit and apply more extreme adjustments, select the Corner option after inserting a point on the curve. When you insert and move a second point, the curve becomes angular.
Inserting a point and selecting the Corner option. Adjusting new point makes the curve angular at the point where the Corner option is used.
Equalize Histogram. Compresses the dynamic range of the HDR image while trying to preserve some contrast. No further adjustments are necessary; this method is automatic.
Exposure and Gamma. Lets you manually adjust the brightness and contrast of the HDR image. Move the Exposure slider to adjust gain and the Gamma slider to adjust contrast. Highlight Compression. This causes bits to be equally spaced throughout the dynamic range — allowing for greater bit efficiency. Floating point numbers also ensure that all tones are recorded with the same relative precision, since numbers such as 2.
Note: just as how using high bit depth images don't necessarily mean your image contains more color, an HDR file does not guarantee greater dynamic range unless this is also present in the actual subject matter. All of these extra bits provided by the HDR format are great, and effectively allow for a nearly infinite brightness range to be recorded.
However, your computer display and prints can only show a fixed, narrowrange. This tutorial therefore not only focuses on creating bit HDR files, but also on converting these into images which can be displayed on your computer, or will look great as a photographic print.
This conversion step is commonly referred to as " tonal mapping. Since creating an HDR image requires capturing a series of identically-positioned exposures, a sturdy tripod is essential. Photoshop has a feature which attempts to align the images when the camera may have moved between shots, however best results are achieved when this is not relied upon.
Make sure to take at least three exposures , although five or more is recommended for optimum accuracy. More exposures allow the HDR algorithm to better approximate how your camera translates light into digital values a.
The doorway example is best-suited with several intermediate exposures, in addition to the two shown previously. It is essential that the darkest of these exposures includes no blown highlights in areas where you want to capture detail.
The brightest exposure should show the darkest regions of the image with enough brightness that they are relatively noise-free and clearly visible. Each exposure should be separated by one to two stops, and these are ideally set by varying the shutter speed as opposed to aperture or ISO speed. We also note another disadvantage of HDR images: they require relatively static subject matter, due to the necessity of several separate exposures.
Our previous ocean sunset example would therefore not be well-suited for the HDR technique, as the waves would have moved significantly between each exposure. Here we use Adobe Photoshop to convert the sequence of exposures into a single image, which uses tonal mapping to approximate what we would see with our eye.
First, we need to combine all exposures into a single bit HDR file:. If your images were not taken on a stable tripod, this step may require checking "Attempt to Automatically Align Source Images" which greatly increases processing time. Once your computer has stopped processing, it will show a window with their combined histogram. Photoshop has estimated the white point, but this value often clips the highlights. You may wish to move the white point slider to the rightmost edge of the histogram peaks in order to see all highlight detail.
This value is for preview purposes only and will require setting more precisely later. Note how the image may still appear quite dark; only once it has been converted into a 16 or 8-bit image using tonal mapping will it begin to look more like the desired result. At this stage, very few image processing functions can be applied to a bit HDR file, so it is of little use other than for archival purposes.
You may want to try adjusting the exposure to have this reveal any hidden highlight or shadow detail. This requires interpretive decisions about the type of tonal mapping, depending on the subject matter and brightness distribution within the photograph.
The tonal mapping method use one of four methods:. Before using any of the above methods, one may first wish to set the black and white points on the image histogram sliders see " Using Levels in Photoshop " for a background on this concept.
Click on the double arrow next to "Toning Curve and Histogram" to show the image histogram and sliders. The remainder of this tutorial focuses on settings related to the "local adaptation" method, as this is likely the most-used, and provides the greatest degree of flexibility.
In contrast to the other three conversion methods, the local adaptation method does not necessarily retain the overall hierarchy of tones. Something went wrong.
