If you can still find them, check out Clik Elite Adventure Photography Packs. They are well made, have a excellent hip belt suspension. I bought their Escape about a decade ago, as it had a external pocket for a hydration bladder. I could fit my Canon 60D with battery grip and Sigma 150-500 Lens attached. Click Elite has closed their doors, but they made excellent photography centric back packs.

Check out Clikelite.com, they make adventure oriented photography backpacks. Some also have a external bladder sleeve.
They are well made, and have an excellent hip supension system, something l found lacking in most photography backpacks when I was researching them several years ago

Here is a Link to a couple of LED Light Panels I have been considering for use as "Strip Lights" as requested.
This one is not dimmable as far as I can tell - http://www.homedepot.com/p/Pixi-1-ft-x-4-ft-Edge-Lit-LED-FlatLight-Luminaire-FLT14C40MDUP44A/205910403
This one is dimmable - http://www.homedepot.com/p/Elegant-Lighting-1-ft-X-4-ft-36W-4000K-Dimmable-LED-Panel-Light-2-Units-PANEL1X4-D36-40/207163420
Not sure which version has the "Better" Light, the Back Lite or Edge Lite versions, would have to take readings using a 1 degree spot meter on several samples to find out.
I have used some of the PAR LED Flood Lights as well with some success in the past, I use the 7/16 Window Screen Frames with White Ripstop Nylon for the diffusion material, simply use screen spline to hold the ripstop nylon in the frames. Easy to piece together up to 7' x 7' Diffusion Panels. I have also used Hi - Bay 6 Lamp (T8 6500K) Fixtures for lighting as well, the T8 & T5 lamps don't seem to have the Flicker Problems that I experienced with the T12 Lamps.
I have found for me, that it was easier to work with Continuous Light Sources when I was doing Catalog Photography for Automobile & Medium - Light Truck Calipers and Brake Pads. I did the general setups, determined the Exposure Parameters etc. and then when turn it over to production personnel to do the actual bulk of the work (Several Thousand Calipers, and around a 1000 different sets of Brake Pads and Brake Shoes)
One of the requirements for the Calipers was to have no shadows, so those were also "Bottom Lite" through a piece of translucent white acrylic on a piece of 5/8" Plexiglass (some Calipers weighed 60+ pounds)

I am wondering if any Hoggers have tried using the LED Light Panels sold by Home Depot (4000 - 4100K) for Photography?
It would appear as if the 1‘ x 4' could work as a strip light, and I believe that some are also dimmable. I suspect that they might provide a fairly even diffused light source
Not sure if they are "Full Spectrum" or not, and have not seen a CRI Percentage rating for them.
If so what issues if any, did you run across.
I used to do a lot of product catalog photography where I would bottom light the products to eliminate shadows (clients requirement).

You may want to check out the Adventure Photography Back Packs by ClikElite. I bought one of their Escape series seversl years ago. It has an external hydration bladder pocket with drain that is against your back. The waist belt is designed similar to those of quality back packs, that is to say the majority of the weight is carried on your hips, not your shoulders.
I use Platypus Big Mouth Zip Bladders, easy to clean, and load with ice.
I use it when hiking in the Sierra's to photograph waterfalls etc.
It will handle a FF Body (my 60D with Battery Grip is equivalent to FF in size). I can carry my 60D with Sigma 150-500 mounted in this pack.
BTW I have a herniated L5-S1 Disc, so I spent quite a bit of time investigating photography back packs.
Mountain Smith used to have a nice Butt Pack with optional shoulder strap set up, but wouldn't fit my camera with battery grip, but great for shorter hikes traveling light.

Take a look at ClikElite Adventure Series Photography Backpacks, they are well made and some models have a external sleeve for a hydration bladder as well. Their waist belt system places the load on your hips, like a well desgned backpack should.

You might want to check Pearstone Dual Compact Battery Charger to see if they support your battery size. I bought one with the Canon LP 6 Battery Plate Adapters about 4 years ago and it is still working fine. It is rated for Input 100 - 120 VAC, 12 - 24 VDC, Output 1.2 -8.4 VDC 2Amp max. It also has a USB 5VDC 2 Amp max port.
If I remember correctly, I bought it from B & H for around $50.

Does anyone make a quality and reasonably priced backpack that will carry a DSLR with the Tamron or Sigma 150-600 mounted? Thanks.


Check out Click Elite's series of Photography Adventure Packs.
I bought one several years ago to carry my Canon 60D with Battery Grip and Sigma 150-500 attached.

I have a bad back so it was important for me to have a good hip support waist belt support sysrem. I also wanted a pack that would take a water blader as well for hydration which some of their models do.
The seleeve for the bladder on mine is external to the gear compartments, with a built in external draiin.
Well paded & adjutable, materials are all high quality.
At the time Click Elite were the only Photography Back Packs that I found built with the load carring features of true Back Packs.
I believe I bought mine from B&H.

At what percentage of the image size (1-100%) is considered optimal for judging the sharpness of a image on a monitor?
Camera is Canon 60D (18 MP), Images are Large RAW, monitors are 23" - 27", differen't computers.
Monitors are set for 1080 x 1920 resolution.
I know that the images appear sharper at 25% than they do at 100%.
Off hand I don't remember the exact Pixel Count of images, but believe it is roughly 4,700 x 3,500.
Typically look great at 25 -30% but soft at 100% +

I have been doing some research on line and believe that I have found the underlying reasoning.
It is similar to taking a image sized to be 1" x 1" @ 72 DPI and printing it at 3" x 3", the resulting jaggies (pixelization) in the image would make it appear terrible.
I believe that current monitors, like their CRT predecesors have a "Dot Pitch" or equivalent specificarion.
If you exceed 1 image pixel per Dot Pitch, you end up with an effect similar to pixelization when printing.
The more image pixels per Dot Pitch, the smoother/sharper the image appears as well as the greater the viewing distane, the smoother/sharper the image appears.
I also ran across some comments that percentages other then those divisible by 2 or multiples of 2, can induce jaggies (no explination as to why).

I am refering to my culling process for "keepers". I am not "pixel peeping". I am curious as to what others do in their selection process.
I believe that monitors are typically considered to display at 72 or 96 ppi and I am assuming that.what I am refering to as softness is "Pixelation"
akin to the "Jaggies" effect when a raster image is enlarged to much.
When applying sharpening to an image, I do so at 100%.
I also understand that the viewing distance is also a factor in the perceived image sharpness, the same as it is with prints.

I am passionate about photography and hiking and have been trying without success to find a bag to carry a full frame DSLR, couple of lenses, a hydration pack and some survival gear. Appreciate any suggestions.


Check click elite's web site for their back packs, many of them include a external sleeve with drain for a hydration bladder up to 3 liter if I remember correctly.
Great quality, hip suspension system like quality back packs.
I believe I bought their Adventore Model several years ago, it fits a Full Frame DSLR.

PaintShop Pro is an Digital Darkroom Editor, Corel also has a product called AfterShot Pro which is more akin to Lightroom.
They are frequently on sale from Corel's Web Site.
I have found that AfterShot Pro is faster than lightroom, and you don't have to restart the program when you change catalogs.
I believe AfterShot Pro is currently Version 2 and is 64 Bit.
PaintShop Pro's features place it between Adobe's Elements & Photoshop.
Paintshop Pro has a scripting language which allows you to create "actions" not only by recording key strokes, but by coding.

Is there some help for me out there??


I am assuming that you are interested in camera specific information, Blue Crane Digital probably has a Canon T3i video tutorial, there were (2) DVD's for my Canon 60D, also I would check Amazon for a T3i Compact Field Guide by David Busch (I like the Kindle or PDF versions and keep them on my Infinity tablet), I have the one for my 60D, it explains not only the "How" but also the "Why" for many of the settings.
Also check Lynda.com & Kelbyone.com for tutorials specific to your camera. Both sites also have many tutorials related to photography in general as well as Photoshop & Lightroom.
You can also find video clips on YouTube for your camera as well as tutorials on photography and photography software.
Personally I find the Video CBT (Computer Based Training) Tutorials are better for showing/demonstrating many of the more subtle aspets of photography than books in many cases.
Canon's Web Site also has some video clips on camera features & their software.
I also like Digital Photography School's Web Site, and have about a dozen or so books from various authors sold on the site. One of the authors has a very good book on Canon's DPP Program on his site.

People learn differently, you may want to check out the camera specific videos from Blue Crane Digital (bluecranedigital.com). When I was first learning how to use my Canon 60D I bought both DVD's for my camera to help shorten my learning curve. Since photography is a video medium, l find video/CBT (Computer Based Training) a better method than reading a book for somethings, such as explanations of differences in lighting effects.
You might also check out Lynda.com & kelbyone.com web sites for videos on photography. There are also aftermarket books for your camera that explain the Why for the various settings, not just the How as the manufacture's manual does.
There are also short videos on YouTube as well.
