The reason there haven’t been any posts this week is that I’m in the Cayman Islands this week. So it seems appropriate that this weeks Underwater Wednesday post is from this weeks images. This one is from yesterday.
I’m editing this in Lightroom on my laptop. So let me know if this looks too over or underdone as my laptop’s display is not the most accurate.
These guys are filter feeders. And when disturbed they pull back into their base.
This tip falls into the category of pretty slick but from a practical standpoint it’s not something that you will do very often. It has to do with outputting custom sized versions of images directly from Bridge/ACR without have to go into Photoshop. This is; it’s a procedure to mimic, in ACR, what can be done in Lightroom’s Export Dialog.
When CS4 was introduced the hot new feature in ACR was the ability to perform localized edits. With this added capability, for many images, there was no compelling reason to bring the image into Photoshop for additional editing. All edits could be completed in ACR.
Until recently I thought that the only way to specify the size of the output was with the Workflow Options link at the bottom middle of the ACR dialog. It looks like a hyperlink and when you click it the Workflow Options dialog opens. This is where you specify how you want your image sent to Photoshop or output directly as a tif or jpg file. In addition to specifying the size the Color Space, Bit Depth, Resolution, and Level of Sharpening can be changed. Read the rest of this entry »
This is another shot from the Nature Close-up class field trip to Ridley Creek Stat Park. What caught my eye on this one is the back lit seed head. I like how the two oof white areas, one in LLHC and the other in the URHC, mimic the color and shape of the seed head. Also the the oof swirls of green worked out well.
(After looking at this for a bit I think that oof white area in the URHC is the diffuser I was using to shade part of the bg. Goes to show you that mistakes can work sometimes.)
A simple composition, just a barrel sponge with a crinoid setting on top. Shot at a slight upward angle to put blue water (and the surface) in the background. The sun ball and the light rays running through the blue background keep the blue from dominating the image.
Shots like this remind us that no matter the type of photography; landscape, sports, portraiture, or even underwater, It’s All About the Light!
Ok, I’ve been a bit tardy in getting this last segment of the series out. Now that the classes I’ve been teaching are winding down things should return to normal. And I should be able to post on a more regular basis. To get you back on track with this series on sharpening in Lightroom (and remember that all of this applies equally to Adobe Camera Raw) here are links to the previous three posts:
Now on to Output Sharpening.
Output sharpening is the final form of sharpening that will be applied to images. The biggest factor affecting the level of sharpening that should be applied for output is the image size; that is, the pixel dimensions of the output file. So output sharpening should only be applied at the end of the process, after the image has be resized for a specific output. Image files destined for display (web site, email, or projection) are typically small in size and only require small degree of sharpening. However, image files intended for print can be fairly large and require a higher degree of sharpening. In addition, output sharpening of print files needs to compensate for the loss of sharpness introduced during the print process due to dot gain–the spreading of ink when it is applied to the paper. This leads to the need for different levels of sharpening for different paper types. Typically files printed on matte papers require more sharpening, because the ink spreads more, than when printed on glossy (or semi-glossy) papers. Read the rest of this entry »
As I mentioned in my last Wildflower Post, last weekend I did a field trip to Ridley Creek State Park with my Chester County Night School Nature Close-up Photography class. For the field trip John Koskulitz was helping out. So when I was not helping students I took the opportunity to shoot some. And at our final classroom session we critiqued some of their images. At the end of the session they want to know if they could see some of the images I shot that morning. I couldn’t show any at the session because I didn’t have them with me. But I think I will post a few over the next week of so and share with everyone.
I keyed this out but have forgotten what it is called so I will have to update this when I get home. I’m down in southern Delaware teaching the Beaches and Wildflowers Workshop. Update: this is Canada Mayflower.
The shooting metadata for this image is:
D200 with 105 macro
1/45 sec @ f/3.5 , ISO 100
Matrix, Aperture Priority, Comp +2/3
After shooting this version I added a 36mm extension tube Read the rest of this entry »
