HDR Software Review: Hydra

So I recently got the oportunity to play with & review  an interesting piece of software (review also featured at http://www.sevenbyfive.net/), Hydra from the company Creaceed. Its an interesting piece of HDR Processing software, with lots of potential but unfortuantely brought down by a few minor faults. 

Enjoy the review below :) :

Firstly, What is HDR?

The term has recently entered the jargon dictionary of most photographers out there is HDR. You hear it mentioned regularly by the guys at Photoshop user, and intensively featured again and again in various magazines at different levels of photography. Almost to the point where it needs no introduction. However everyday the art that is photography sees more and more users pick up an SLR or semi-SLR camera, often overwhelmed by what is available in the market. Brands, Lenses, Techniques, Photoshop etc. For those who have only recently began to dip their feet in high end digital photography, or decided to expand their horizons and try out this "HDR" thats been so raved about one must first delve into what HDR stands for. High Dynamic Range. If you're still as confused about what this all means as you were a moment ago, not to worry. Dynamic range is the range that a light sensory device can attain when capturing and interpreting detail within the light. What this means is that whatever the dynamic range of a device is, defines the amount of detail that can be captured within a specific range of light from zero darkness, to so bright its all white. This is why often in cameras when shooting directly into the sunlight either our family is well lit, and the background is completely white, or our backgrounds are relatively well lit with detail, and our subjects are often obscured in darkness. This is because modern camera's simply cannot process the entire light spectrum from absolute darkness to fully white in the same image, unlike our eyes which perform much better because humans have a much wider dynamic range. In the past to combat this often a sacrifice was needed between light and dark, or in more recent times, using flash to light your subject out of the darker bottom of your camera's dynamic range allowed one to successfully balance backgrounds and foreground. However lighting a subject may not always be the desired solution to a lighting situation. Often in landscape situations there isn’t a subject to light that isn’t the building or landscape. So what do you do, if you're shooting in a cathedral, with light oozing in thru the rafters creating this beautiful scene? Only to realize your camera will only let you expose so that those beam of lights are surrounded by darkness loosing the gorgeous detail that is the cathedral except for what’s lit? Or do you keep the cathedral and blow out those shafts of light. Curse my camera's dynamic range you think! (Or not). You're on location and certainly not equipped to expose for the shafts of light and flash the bajeebers out of that cathedral. So what do you do? Well you do expose for both! Thankfully modern Image processing has come up with a technique (HDR) which allows us to artificially expand our camera's Dynamic range by shooting the same scene at various ranges, and essentially piling the various exposures on top of each other to recreate the scene our eyes gloriously basked in which was being, "under-appreciated" so to speak by our camera. And the best part is, all you need is your camera, and one of many available HDR software available out there. Making it a quick, easy and professional solution to capturing those scenes just as our eyes saw them. Ladies & Gentlemen the magic of HDR

The Software

The HDR Scene has been predominantly dominated by Photomatix with their Lightroom Plug-in, or standalone version. Made easier as such by Lightroom's ability to quickly "merge to HDR" in Photoshop, creating a merged Image in Photoshop which could quickly have the photomatix plug-in filter applied to it, to bring out more customized sections of the dynamic range. Enter "Hydra" another contendant in producing those lovely HDR Images we all love. Available only for Macs in Aperture and Stand-alone flavors (coupled with a lightroom plug-in). Presenting itself in a lovely and what appears to be, simple UI, the software appears to be very promising indeed. Unfortunately this is not the case as its simple interface is essentially its downfall. Like most users who consider themselves computer literate, I quickly delved into the software not interested in going thru guides, or documentation. However I quickly discovered that this would unfortunately be inevitable. With various unexplained modes, buttons, tabs and jargon, I was at a loss of where to begin or what did what.

Being a heavyweight lightroom user my first priority was to install the advertised lightroom plug-in. This was unfortunately not explained and took me about 30 minutes of scouring their website and Google before figuring out there was an install option located inside hydra’s file menu. Having accomplished such, I went into Lightroom, and selected six of the images from my recent trip (a landscape) to convert to HDR. As opposed to using the “merge to HDR in Photoshop” function, Hydra requires you to use the export panel to make use of its plug-in. So I dutifully exported the Images, using the originals to maintain maximum dynamic range and under Hydra options I set it to Tiff8 Simply because my computer is old and rickety.

Once Inside Hydra I was greeted by an artful UI, Displaying the Images I had chosen on the left with a “result” large central Image.

Not knowing what was obviously available I clicked Render, assuming it would bring up some dialog boxes of some kind. I quickly discovered it was the render button, producing a grayed out jpeg, similar to the initial image you get when “exporting to HDR” in Photoshop. However considering the framework of the software I don't think that's what was supposed to come out.

Upon my second trial and doing some reading on the website I discovered that the little dialog box to the right (the transparent one) is the software’s control panel and where all the fun happens. If you see there are four options along the top, Import, Align Merge (or fusion) and Pro.

For the purposes of the review I tried out the Align option and found it to be a nice addition in being able to fine-tune the software’s align feature, however I eventually left it on automatic as I found it did a pretty good job of aligning the Images.

The Merge button is essentially the most important one in the software, transforming the tool dialog into the sliders that give your image that HDR look. And of course leading to the confusion.

Initially this is what you will get

This left me quite stumped, as it appeared a little too simple. And Upon investigating the three methods in the dropdown box to and finding them to be independent of each other, I was confused as to how to get the results I wanted. That's what the final pro button is for.

Opening up options more closely tuned to those available in photomatix.

The rest is simply a matter of playing with the modes (HDR & 8Bit) and shifting the sliders to get a desired result. Something, which is also not clearly outlined (I.e. what do I play with for a specific outcome)

Image Critique

Below are the 7 Images I used to produce the final HDR Image (3 Stops Below, Above plus the “correctly” metered Image)

And this is the final Image I outputted from Hydra

As you can see the colors are considerably more punchy, and I have managed to retain most if not all of the detail from the previous Images.

The software manages to produce Images in a variety of output options form TIFFS to PSD’s to simple Jpeg’s making it easy to incorporate into any workflow. The quality of the Images are of a high enough caliber to compete with Photomatix, although it may not be as visible thru these Images due to the compression for web, but Noise Levels are low, and detail and sharpness is well maintained, as well as colors.

Conclusion

Overall Hydra is a sturdy and well-rounded piece of software with lots of potential in producing incredible HDR Images. Its biggest flaw would be its UI and its inability to properly explain itself. Some work in explaining what each slider does In Software (even a first time “what does this do” dialog box which opens the first time (and every progressive time unless the checkbox do not open anymore) with some explanations would go a long way in making this more user friendly than it already is. Everything is laid out in front of the user, in an easy to view format, it just needs some clarifications and tooltips. Overall a descent piece of software

Bringing 2009 to a close

Well its been a couple of days since my last post, it seems that living in a Salon/Tv room with family coming out ones ears is apparently not the most blog-inspiring situation...at least not for me anywais. Whilst I love my family dearly theres only so much chaos one can take. Finally they have left, heading back to Europe :(. I am able to return to my daily routine and most importantly my room.

As I'm sure most if not all (I'd be worried if it wasnt all) of you have realised we have only just recently entered not only a new year but a new decade! This brings about a lot of change in the way people are viewing the new year, as everything we do for a first time particularly as a trendsetter has the potential to mark the outcome of not just our year but the next ten years! I find it particularly interesting that it was at the begining of this last decade that I found myself first coming to the Philippines to study...and yet here I am once again ten years later. One can only marvel at the co-incidences of the world. I wonder where I'll be when we hit 2020.

Anywho my close to 2009 was rather less glamorous than I would have liked. It involved a small family Dinner and then a sitting (or in my case frantically running around with a tripod to shoot the fireworks) and viewing of the fireworks, and then a return home, where my newly gifted xbox ruled my hours until the wee morning. Fun I know, but the option of partying the night away was rather difficult at this point. Something I hope will result differently next year.

Over the next few days I will be posting up the few remaining sets and posts of 2009 before I close it up with an annual review post & video so keep your eyes peeled folks!

2008 began quite slowly for me as a photographer, but with two particularly important shooting oportunities. One beeing my trip to paris producing a vivid new environment for me to shoot in, resulting in some of my fave images of the year. I was also able to have my first proper photoshoot after having joined the NAPP and benefiting from the ounces of knowledge made available to me. throughout the month the only other memorable shoot was the opportunity to shoot the 3 kings celebrations as they passed the floats through the streets.

three kings/xmas celebrations





Febuary and March were rather slow months for me as a photographer, the only pictures beeing results of "work". In Febuary aside from a party at my dorm that I was asked to photograph and som other random social portraits I was devoid of proper shooting oportunities. However despite that I was quite happy with the results of some of the images from the party proving my slow but steady mastering of flash photography.



March As I mentioned was devoid of photography minus some portraits for Asian woman of Director Imtiaz ali and actress Karen David. which due to ownership issues I cannot at present post.

In April my photography picked up considerably, with some shooting done at the local airport, portobello road market, and of course Photoshop world! bringing to me my latest upgrade in photography my new camera body the 40D! and my Pocket Wizards and additional strobes giving me full power on off camera flash photography, and of course my first oportunity to try it out, the photoshoot I did with my cousin in the tight confines of my room which ended up producing some rather impressive images.



May once again slowed down due to the increasing ammount of deadlines and procrastination, however that didnt stop me from my seccond photoshoot making use of my off camera strobes



June
In June the photos began to pick up once again as I was home for the summer. I also took the oportunity to organise a sunrise photoshoot on the beach which turned out brilliantly!

July Continued with my photography, however this time it was based more on clearing backlog from previous months and some heavy duty photoshop studies. However despite that I managed to arrange a little shoot to help me try and shoot jewellry in a fashion context. This is the month that I also began my travel to the US stopping by LA and in August New York. I was also able to shoot at the salon de comic de benalmadena in malaga extending my networking into the local anime community.



August Began in New York a gorgeous city for photography, with oportunities cropping up left and right. However what followed, the city of pittsburgh proved to be the complete oposite as it always does. However thanks to Model Mayhem I was able to meet with a lovely model who introduced me to an artists hangout, a brilliant photoshoot and her husbant another fellow photographer.


September brought the beggining of the end of summer. I was also able to work under Nacho Alcala a National Geographic photographer who although having only met him twice was able to greatly open my photographic eyes. I hope to meet him more often upon my return to malaga. Aditionally I also spent a weekend in madrid, proving to be very exhausting and usefull as I met Hitesh Sawlani (www.hitkaiser.com) and his merry band of photographers to go and shoot a classic motorbike run and the famous anual white night of madrid!




October brought the return to uni and a frantic house hunt/move in leaving little time for photography except for a shoot for Asian Woman of renowned Bollywood film director Karan Johar
November brought me back to the studio as my friend Lavina volunteered to do a shoot with me, resulting in much better shots than I had anticipated. Certainly since my last time in the studio which was January.

December the last and final month of the year has been quite photo heavy, with me making a trip up to bristol, adn finally making my first trip with the London Photo and graphics meetup group and an anime group which I meet weekly, as their oficial photographer designer (North East london anime society). The London Photo and Graphics meetup went extremely well and I hope to frequent it much more in the comming year.



In Conclusion 2008 has certainly been an impressive year in terms of my photography. With the resources made available to me and the oportunities to shoot i feel I have made leaps and bounds in the quality of my photography. Something that I hope will continue in the comming year.
