This image of a huge breaking wave was created at 7:23 am on April 1, 2012 just north of Morro Rock with the with the tripod-mounted Canon 800mm f\/5.6L IS lens<\/a> and the Canon EOS-1D Mark IV<\/a>. ISO 400. Evaluative metering +1 2\/3 stops: 1\/800 sec. at f\/5.6 in Manual mode. <\/p>\n

Keep or Delete?<\/h3>\n

Would you keep or delete the image above? Before you answer, there are several important concepts to understand:<\/p>\n

1-With images of over-all light-toned scenes made when the sun is at less than full strength you generally need to add at least two stops of light to get some data half way into the right most box of the histogram. <\/p>\n

2-When you expose such images properly they will (properly) look washed out on the back of your camera and then again on your computer monitor. <\/p>\n

3-Such properly exposed digital images have huge potential. <\/p>\n

4-The reason that you need to expose to the right in these low light\/overall light-toned situations is to produce files with the greatest amount of information. If you do not believe me, simply photograph the pre-dawn sky at -1 stop and then again at +3 stops. Now download the images and compare the file size…. Let me know what you learn. <\/p>\n

The optimized image that I created from the image above appears below and was first published in this recent blog post: “Frozen and Battered.” If you missed that one click here<\/a>. <\/p>\n\n\n\n

This is the optimized image created from the image capture above. <\/p>\n<\/td>\n<\/tr>\n<\/table>\n

Magic?<\/h3>\n

Nope. There was no magic involved. The image was converted in ACR as described in detail in Digital Basics<\/a>. Note: if you set the Black point by moving the Black slider to the right while holding down the Alt key (the Command key for Mac) and your image looks too dark or too contrasty simply move it back to the left to taste. <\/p>\n

After converting the RAW file to a TIFF and bringing it into Photoshop I brought the image into NIK Color Efex Pro. I ran Tonal Contrast at 80% and Detail Extractor at 50%. I guess that that might qualify as magic as it really juiced up the image. I used a large soft brush to erase the NIK effects from the sky; you almost never want to run Detail Extractor on the sky and the same is usually true of Tonal Contrast….<\/p>\n

BTW, though I saw the top image while looking at the back of the camera I saw the optimized image in my mind’s eye. Heck I visualized it as I looked through the viewfinder. And even though the image on the back of the camera looked totally washed out I loved it from the moment I saw it :). <\/p>\n

ps: I kept it!<\/p>\n

Shopper’s Guide<\/strong><\/h3>\n

Below is a list of the gear used to create the images in today’s post. Thanks a stack to all who have used the Shopper’s Guide links to purchase their gear as a thank you for all the free information that we bring you on the Blog and in the Bulletins. Before you purchase anything be sure to check out the advice in our Shopper’s Guide<\/a>. <\/p>\n

Canon 800mm f\/5.6L IS lens.<\/a> Right now this is my all time favorite super-telephoto lens.
\nCanon EOS-1D Mark IV professional digital camera body.<\/a> The very best professional digital camera body that I have ever used.<\/p>\n

And from the BAA On-line Store:<\/strong><\/h2>\n

LensCoats<\/a>. I have a LensCoat on each of my big lenses to protect them from nicks and thus increase their re-sales value. All my big lens LensCoat stuff is in Hardwood Snow pattern.
\nLegCoat Tripod Leg Covers.<\/a> I have four tripods active and each has a Hardwood Snow LegCoat on it to help prevent further damage to my tender shoulders \ud83d\ude42 And you will love them in mega-cold weather….
\nGitzo GT3530LS Tripod.<\/a> This one will last you a lifetime.
\nMongoose M3.6 Tripod Head.<\/a> Right now this is the best tripod head around for use with lenses that weigh less than 9 pounds. For heavier lenses, check out the Wimberley V2 head<\/a>.
\nCR-80 Replacement Foot for Canon 800<\/a>. When using the 800 on a Mongoose as I do, replacing the lens foot with this accessory lets the lens sit like a dog whether pointed up or down and prevents wind-blown spinning of your lens on breezy days by centering the lens directly over the tripod.
\n Double Bubble Level.<\/a> You will find one in my camera’s hot shoe whenever I am not using flash.
\nThe Lens Align Mark II.<\/a> I use the Lens Align Mark II pretty much religiously to micro-adjust all of my gear an average of once a month and always before a major trip. Enjoy our free comprehensive tutorial here.<\/a>
\nBreezeBrowser<\/a>. I do not see how any digital photographer can exist without this program.<\/p>\n","protected":false},"excerpt":{"rendered":"
